* More debug command cleanup to save spaceRandall Spangler2012-05-211-43/+32
| | | | | | | | | | (saves another 1.5KB) BUG=none TEST=(run the commands) Change-Id: Id3ca58528fa68a4cec606edf2b98b9af38ac228f Signed-off-by: Randall Spangler <rspangler@chromium.org>
* Add LM4 support for hard resetRandall Spangler2012-05-211-5/+13
| | | | | | | | | | | | (And add STM32 support for disabling interrupts before reset, which got missed before.) Signed-off-by: Randall Spangler <rspangler@chromium.org> BUG=chrome-os-partner:7470 TEST=from console, "reboot", then "reboot hard" Change-Id: Ib98792abc0c91a01e2230b419fc876052380655a
* Fix partition address when flash base is not zeroVincent Palatin2012-05-181-3/+3
| | | | | | | | | | | | | On chips where CONFIG_FLASH_BASE is not 0 (e.g. stm32), the reset vector address check in system_run_image_copy would fail because we are comparing an absolute address against a flash offset. Signed-off-by: Vincent Palatin <vpalatin@chromium.org> BUG=chrome-os-partner:8865 TEST=on Daisy, type "sysjump B" in EC console. Change-Id: Ib79677fb926a37fcf32f4aac013dc36b086f4464
* de-LPCify the EC host interfaceVincent Palatin2012-05-151-31/+31
| | | | | | | | | | | | | Preparatory work to use common host command code between ARM and x86. Just rename constants, do not change the binary API.

* Slightly update the host commands APIVincent Palatin2012-05-141-6/+9
| | | | | | | | | | | | | | | | | | | | Preparatory work to use common host command code between ARM and x86. Every command sends back explicitly the size of the response payload. The size of the response defaults to 0 ond can be updated. Add a protocol version number returned as command 0x00 to help with backward compatibility. move a couple of function from lpc specific header to host commands to be able to implement them for the I2C link.

* Maintain timer value across sysjumps and clean up init debug outputRandall Spangler2012-05-111-1/+1
| | | | | | | | | | | This helps us keep track of how long vboot is taking on the EC.

* Add header_size in struct jump_data.Louis Yung-Chieh Lo2012-05-031-1/+38
| | | | | | | | | | | | | | | | The position of jump_tags was shifted every time a new field was added to struct jump_data. This broke the sysjump hook badly. To make this more scalable, add a header_size field in struct jump_data. Then the new code can always prepend (or reduce if jump_data becomes smaller) some spaces between jump_data and jump_tags. BUG=chrome-os-partner:9447 TEST=EC upgrade from EC 517 (2231) to this version, and keyboard keeps working. Note that EC 526 (2235) to this version is not working because we have no way to identify that header version change. Change-Id: If1b506c6f7d22e5affaaf8ada15990f60d2f957a
* Enhance LPC EC REBOOT reset command to allow to request recoveryVadim Bendebury2012-04-301-19/+41
| | | | | | | | | | | | | | | | | | | | | | When the host reboots the EC it should be able to request the EC to force recovery mode after reset. This is achieved by extending the REBOOT EC command with a bitmask byte, with bit 0 dedicated to recovery request. So, when BIOS on the way up determines that recovery is requested, but the EC is not running from the RO space, the BIOS would reset the EC forcing it to run from RO and to request recovery mode through the LPC bitmask. Then BIOS will restart itself ensuring that the system comes up in consistent state. Some refactoring was also done to make the code a bit more compact. BUG=chrome-os-partner:9040 TEST=manual . tested along with coreboot changes (test described in the coerboot CL).

* Refactor async console outputRandall Spangler2012-04-241-29/+32
| | | | | | | | | | | | | | | | | | This adds a 'ch' command which prints/sets which channels are active This handles all the async output; the remaining debug commands will be refactored to use ccprintf() / ccputs() in a followup CL. Signed-off-by: Randall Spangler <rspangler@chromium.org> BUG=chrome-os-partner:7464 TEST=manual ch --> all channels active ch 0x100 -> just port80 active powerbtn -> system boots; only port 80 codes shown on console Change-Id: I9efc43acec919b62b78c2c82c61946d32380adfe
* Implement HOOK_SYSJUMP and use it to preserve LPC host event maskRandall Spangler2012-04-191-11/+102
| | | | | | | | | | | | | | | | | | | | This also changes shared_mem to use all the remaining RAM, instead of reserving a fixed-size buffer.

* flash write and erase commands protect the active image.Louis Yung-Chieh Lo2012-03-271-0/+31
| | | | | | | | | | | | | | | Comapre the range to be write (erase) with the range of active image. If overlap, return error to indicate the access denied. Note that we actually protect only runtime code and ro data. FMAP is intentional unprotected so that flashrom can update to new map before jumping. Since the vector table and init code are in the same erase page, they are unprotected as well. BUG=chrome-os-partner:7478 TEST= Change-Id: Icb5cc89836432a11cef80e18eb66bb39a6c9b1d9

| | | | | | | | | | | | | | | | | Now that we can jump directly to other images, we don't need this. We jump to image A by default, unless the recovery button or signal is asserted.

* Support warm reboot from one EC image to another.Randall Spangler2012-03-191-23/+123
| | | | | | | | | | | | | | | | | | | | | This is necessary at init-time for verified boot to jump from RO to one of the RW images. It's also used by factory EC update to update one image and then jump to the updated image to finish the update. In this case, the x86 does NOT reboot.

* More cleanup of board/chip configs and initializationRandall Spangler2012-03-191-0/+263
More modules can be disabled individually through CONFIG_ defines. Reordered early module pre-init and init, and added comments to explain why things are ordered in main() the way they are. Fixed a few assorted init-related bugs along the way, like st32m keyboard scan double-initializing.
