This has been bothering me literally for years: once in a while there
would be tons of files in /tmp directory named tmpXXXXXX where XXXXXXX
is some random string.
Finally, it became clear that the files are generated when 'make
buildall -j' is called in the ec directory. Next step - it looks like
one of the culprits is building for board named 'chell'. Indeed, this
board uses its own version of cmd_obj_to_bin make function, which,
among other things invokes the pack_ec script to pack the image.
The script was creating temporary files and leaving them behind.
This patch makes the name pattern of the temp files better
recognizable, juts in case, and makes sure that the files are deleted
once they are not needed.
BRANCH=none
BUG=none
TEST=invoking 'make buildall -j' still succeeds but does not result in
leaving temp files behind.

The MEC1322 is optimized for 96k code RAM and 32k data RAM, therefore
the default MEC1322 boards should follow this.
On GLaDOS and Kunimitsu, we cannot fit all of the data in data RAM,
therefore we adjust this boundary slightly.
This should not be moved further as this represents when we are truly
out of space.
128k image:
-3k loader
-1k for shmem/panic info
-24k RAM for RO/RW
-100k for RO/RW .text and .rodata

1. No need for loader data ram
2. 97K code size
3. shifting down RO/RW image location in RAM by 1Kbyte.
(loader code space: 4k to 3k)
BUG=none
TEST=1. build image with big code additions.(like low power idle patch)
and check if there is flash size related error message.
2. check if EC's RO image can boot from loader.
3. use EC console command, "sysjump RO/RW" and check if it works.
4. Verified in Cyan and Kunimitsu.

mec1322 only has 96KB program memory, vs 256KB
flash space on lm4.We no longer have enough program
memory to load both RO and RW at boot. We'll want to
implement a small loader program that will load either
RO or RW from flash, and then jump to the loaded image.
CONFIG_FW_INCLUDE_RO is enabled to include RO image into
the build.
pack.py script is altered to load the (lfw + R)O on boot.
Software sync is not added.Distinguish between
RO/RW is yet to be added.
flash_ec is altered to support padding 0xFFs to 256k ec.bin
to match the size of the SPI flash of the board.
BUG=chromium:37510
BRANCH=None
TEST=Make -j buildall,Verified ec.bin to be 256k.
Verified RW image at offset 0h and (lfw + RO) at offset 2000h.
On boot sysjump to lfw. lfw checks in shared SRAM (currently RO)
and jumps to RO image.

The current header location is too large for small SPI flash chips.
Since this value is only used for private EC SPI, it doesn't really
matter what it is. Let's just move it to 0x0.
Note that this doesn't affect shared SPI case, as we need a more
sophisticated packer for that.

For boards without a shared SPI, it's reasonable to use a SPI flash
smaller than 1MB. Change the script to allow this.

Adding two signing keys:
- A dev key used to sign header. We have confirmation from Microchip
that we can check in this key.
- A key to sign payload. This can actually be an arbitrary key as long
as the header and the payload are in sync. Adding a key here just
for convenience.

This script is needed for packing EC binary into SPI flash for MEC1322.
This includes adding tag and header at appropriate location and signing
the image. Signing key, for obvious reason, is not included here until
we are sure what key we want to check in.
