This change adds a send_done call at the end of show_fw_ver. With this
change Cr50 will set the state to rx_idle after every usb_update -f
call.
Cr50 cannot process any vendor commands unless the updater state is
idle. After a vendor command is sent cr50 wont set the state to idle
unless it receives a send_done call. It will also reset the state if it
sees that it has been more than 5 seconds since the last transfer.
In the current state you cannot use usb_updater -f back to back because
usb_updater doesn't call send_done through the -f path. If you wait 5
seconds between calls, then it will work. If the call fails and you keep
retrying waiting less than 5 seconds between calls, then it will fail
forever. The last transfer time will get reset with each call and Cr50
will never reach the timeout to reset the usb_update state to idle.
BUG=none
BRANCH=cr50
TEST=run 'sudo ./usb_updater -f && sudo ./usb_updater -f'. Verify both
calls succeed.

The BIOS had the tablet mode device enabled in CL:439308, however
the corresponding change to the EC never was done. Therefore, powerd
was monitoring the tablet mode device which always reported tablet
mode because it wasn't reading the real state. As such the keyboard
and trackpad were never being unhibited by powerd. Ensure the EC
config matches the BIOS changes so that the correct state is properly
reported.

When the charge ramp task starts, it starts up in the DISCONNECTED
state. From this state, it's possible to set the input current limit to
0 mA. However, upon task start, we shouldn't take any action until we
have valid values from a new charge supplier or a supplier leaving.
This commit changes the charge ramp task to not touch the input current
limit until the charge ramp state changes or the desired input current
changes at least once.

Previous boards that implemented tcpc layer on chip didn't support
variable Rp values. However, servo_v4 can present any of the 3
possible Rp values and therefore the voltage thresholds that are used
to determine a no-connect or Ra attach status need a way to be set
based on the Rp value that's current attached to a given CC line.
- Added port and cc line selection to both the CC_NC and CC_RA macros
and now check if they are already defined before being defined in
usb_pd_tcpc.c.
- Defined each of these macros in board.h to use a function that's
able to select the threshold based on the current Rp configuration.

This CL adds support for the DUT port to advertise different current
levels via the Rp resistor selection. The default setting is USB (500
mA).
The board_manage_chg_port function relies on the off->on transitions
only occurring when the CHG port is in a steady state condition. When
the charger being used supports PD messaging, the entry point
pd_set_input_current_limit() which is called after receiving a PS_RDY
message. For TypeC only chargers, the entry point is
typec_set_input_current_limit() which is called from SNK_DISOVERY
after only after the max number of hard reset attempts have been
attempted. This is intended to prevent this entry point from being
called when a USB PD charger is connected and the CHG port enters
SNK_DISCOVERY.
When the CHG port Vbus transitions from off->on, a src_pdo is updated
to reflect the current contract on the CHG port and this src_pdo can
then be used by the DUT port when either a new connection is done or
to update it's existing contract.

port. In each case verified that the DUT renegotiates to the 20 and
15V level respectively. Repated the test with Guppy and verifed that
VBUS is at 5V 3A. When Guppy is removed, then the DUT connection
reverts back to the host as the VBUS source.

Add a flash driver for the STM32L4 family.
For write and erase, the code is very similar to other variants
excepted the 'normal' writes need to be perform 2 aligned
32-bit words at a time.
Option bytes are a sligthly easier business since the hardware deals
with the option bytes page preserving and erasing for us.
For the write-protection, the STM32L4 is slightly different from the
other variants. The write-protection granularity is still a 2-kB block
(2kB here) but instead of having a 'bitmap' of the protected blocks, it
defines 2 write-protection ranges (WRP1AR and WRP1BR).
For the EC code base, we are using WRP1AR to protect the Read-Only
regions and WRP1BR to protect the Rollback and RW regions (if they
exist).

The pstate structure is written using the low-level
flash_physical_write() function. As a consequence, it is supposed to
meet the CONFIG_FLASH_WRITE_SIZE alignment constraint.
Add a build-time assertion to avoid silent failures.
Slightly decrease the maximum size of the serial number string, so the
structure has a natural 32-byte alignment which is compatible with a
large number of platforms (including STM32L4 which requires 64-bit
alignment).
Of course, this change is not fully backward-compatible.

The cr50 code might need access to certain variables stored in the TPM
NVMEM. In particular the upcoming FWMP support will require reading
the NVMEM FWMP space.
This patch adds a generic function which allows to access TPM NVMEM
spaces. The implementation was borrowed from NV_REad.c in the tpm2
tree, the only difference being that the location, if present, is read
unconditionally, without checking access controls.
The API accepts the NVMEM index in Chrome OS scope and maps it into
TPM2 specification's NVMEM index space based at HR_NV_INDEX. The
definitions are included straight from the tpm2 tree.

randomly change. This seems the cause of b:35648317.
We enabled IADP to fix b:35647661 initially and also followed
the vendor's recommendation. However, the issue is only
reproducible on the particular board which was used for power
measurement and we did not see the issue on other boards with
IADP disabled.
Also the vendor assumed our EC doesn't control IBUS_LIM_SET
and ICC_LIM_SET. (I think they assumed like other thier customers
our EC controls ILIM by DAC connected to IADP/RESET pin.) If ILIM
is not set by EC and IADP is disabled, the system would brownout
because ILIM stays at 128mA. Therefore, it was (mistakenly)
recommended that our EC should keep IADP enabled.
Cros EC configures IBUS_LIM_SET and ICC_LIM_SET dynamically thus
the above concern does not apply.
We also found that we have too much noise on IADP/RESET pin. The
noise is not big enough to cause the chip to reset but it's big
enough to cause ILIM to fall in 128mA zone. We think this is why
the boards fail to boot from battery cutoff or no battery.
(Contrary to the vendor's explanation, it seems IADP/RESET pin
continusouly affects ILIM not only in the early chip power-up
period.)
BUG=b:35648317
BRANCH=none
TEST=Booted two Electro and two Snappy from 1) dead battery 2) no
battery 3) battery cutoff.

We are still building two images - for prod and dev fused H1 chips.
This requires different pairs of RO images and calls for using
different keys when signing RW images.
Each produced image is of 512K bytes in size, the ROs are paced at
offsets 0 and 0x40000, the RWs at offsets 0x4000 and 0x4000.
The signed ROs come from their respective source, their processing is
limited to converting into binary format and verifying that their key
signatures match image designation (prod vs dev).
The RWs binaries are derived from RW elf files which are the result of
running 'make BOARD=cr50'. The elves are converted into binary format
and signed, the bs script is used for that.
The bs script is modified to accept the destination file name from the
shell variable, to detect signing failures (resulting in zero sized
binaries), and to fix error reporting.
The new script create_released_image.sh expects exactly six command
line parameters:
<prod RO A>.hex <prod RO B>.hex <dev RO A>.hex <dev RO B>.hex \
<RW.elf> <RW_B.elf>
and generates two cr50 binary images.
The generated images are placed in the directory named cr50.r<ro
vers>.w<rw vers> (the versions are retrieved from the binaries using
usb_updater), and then placed in the tarball with the same base name.
This naming convention is imposed by the ebuild pulling in the tarball
from the binary component server (BCS).
On the successful completion the script prints out commands which can
be used to upload the new tarball to the BCS.
BRANCH=none
BUG=b:35587234
TEST=ran the script to generate the r0.0.10.w0.0.18 release, verified
that all components of both imagea are properly signed (are
bootable and the key signature matches the prod/dev convention).

With the rest of support in place, this patch adds code which would
corrupt the headers received during firmware updates.
The VENDOR_CC_TURN_UPDATE_ON vendor command will be required to enable
the new images.
Care should be taken that other commands operating on the inactive
image header do not do anything with it before it was enabled, some
code is being added for that.
The minor RW version is being bumped up to 19 to clearly indicate that
the device is expecting the vendor command to enable the new image
(this is used by usb_updater when downloading the image without the -p
or -u command line options).
BRANCH=cr50
BUG=b:35580805
TEST=verified that the new image can be installed and started by the

With the upcoming availability of the downloaded header corruption,
there needs to be a mechanism for usb_updater to restore the corrupted
header, so that the downloaded code can run right away.
This patch separates image download and reset functionality. Download
happens as before, and the UPGRADE_DONE PDU is sent immediately once
image transfer completes. This puts the receive state machine into the
idle state and allows to send other commands.
The reset function is different for the target supporting protocol
versions 5 and above. The only command version 5 recognizes is the
indirect reboot command (the UPGRADE_DONE PDU sent the second time in
a row). For protocol version 6 and above the reset could be immediate
or posted, and for targets running RW version 19 or above the command
to restore the corrupted header is required.
When running on the target the command to restore the corrupted header
would be generated by the AP firmware on the reboot.
BRANCH=cr50
BUG=b:35580805
TEST=with the next patch of the series applied observed the corrupted
header properly restored and the device rebooted.

The upcoming move of the Cr50 firmware update to the background
requires postponing the activation of the newly uploaded Cr50 image to
a later point in time, when the AP is ready to switch to start using
the new Cr50 image.
The suggested way of achieving it is as follows: when downloading the
new image, the current Cr50 code modifies the header's 'image_size'
field, setting its top bit to 1. This both makes the size invalid and
guarantees that the new image would not verify on the following Cr50
restarts.
When the AP is ready to switch to running the new Cr50 image, it will
send a vendor command, which would trigger the currently running Cr50
image to restore the other image's size field. This vendor command
would also communicate the timeout for the Cr50 to wait before
rebooting, if there has been at least one header (ro or rw) restored.
Rebooting the Cr50 would trigger rebooting the AP, resulting in the
entire system running the updated firmware.
Response sent to the AP will indicate if there has been a header
restored and the reboot is indeed upcoming, this would allow the AP to
quiesce the state of the device to handle the reboot gracefully.

In order to support waking from Deep S3 the trackpad interrupt
is routed to the EC.
The EC needs to enable this interrupt when going into S3, and
disable it otherwise.
It also needs to filter events and only wake the system when it
is not in tablet mode.
This is accomplished with the following rules:
1) Enable trackpad wake in S0->S3 transition, if !tablet_mode
2) Disable trackpad wake in S3->S5 transition
3) Disable trackpad wake in S3->S0 transition
4) Disable trackpad wake when entering tablet mode in S3
5) Enable trackpad wake when lid angle is <180 degrees and in S3
And finally a check in the trackpad interrupt itself to ensure that
it only sends the wake event if not in tablet mode.
The function to enable or disable trackpad wake uses a static variable
to keep track of the enable state because when enabling the GPIO for
wake it first clears pending events and if multiple transitions are
happening (suspending, plus lid angle rotation) this can get called
multiple times in quick succession.
Currently a placeholder KEY_PRESSED event is used to wake the AP
since we do not have device specific events. Fixing this behavior
is tracked in b/36024430.
BUG=b:35587072
BRANCH=none
TEST=manual testing on eve P1b:
1) ensure that trackpad wake in clamshell mode works
2) ensure that trackpad wake in tablet mode does not waork
3) ensure that if in S3 during transition to or from tablet
mode the wake event is enabled appropriately

PS8751 does not restore all register contents when resuming
from low power mode. This change makes tcpm call board_init
when it stops auto-toggling so that register contents can be
restored.
BUG=b:35585399
BRACH=none
TEST=On Snappy, the board_init funciton is called every time a device
is plugged in and register contents are restored.

Let's split the usb headers in 3 different parts, instead of having
usb_descriptor.h pull in usb_hw.h and usb_api.h.
- usb_api.h: EC functions related to usb (e.g. connect/disconnect)
- usb_descriptor.h: common USB names and structures
- usb_hw.h: Functions required for interactive with EC's USB HW
