2013-02-27smm: Update rev 0x30101 SMM revision save stateAaron Durbin
According to both Haswell and the SandyBridge/Ivybridge BWGs the save state area actually starts at 0x7c00 offset from 0x8000. Update the em64t101_smm_state_save_area_t structure and introduce a define for the offset. Note: I have no idea what eptp is. It's just listed in the haswell BWG. The offsets should not be changed.

Adding RTC init code to the Southbridge initialization code in 'lpc_init'. This initializes the RTC so that the Date Alarm register is set to a valid value (0x00) at startup.

2012-12-12Claim the SPI bus before writes if the IMC ROM is presentMartin Roth
The SB800 and Hudson now support adding the IMC ROM which runs from the same chip as coreboot. When the IMC is running, write or erase commands sent to the spi bus will fail, and the IMC will die. To fix this, we send a request to the IMC to stop fetching from the SPI rom while we write to it. This process (in one form or another) is required for writes to the SPI bus while the IMC is running. Because the IMC can take up to 500ms to respond every time we claim the bus, this patch tries to keep the number of times we need to do that to a minimum. We only need to claim the bus on writes, and using a counter for the semaphore allows us to call in once to claim the bus at the beginning of a number of transactions and it will stay claimed until we release it at the end of the transactions. Claim() - takes up to 500ms hit claim() - no delay erase() release() claim() - no delay write() release() Release() Change-Id: I4e003c5122a2ed47abce57ab8b92dee6aa4713ed Signed-off-by: Martin Roth <martin@se-eng.com> Reviewed-on: http://review.coreboot.org/1976 Tested-by: build bot (Jenkins) Reviewed-by: Patrick Georgi <patrick@georgi-clan.de>

2012-11-14SMM: Avoid use of global variables in SMI handlerDuncan Laurie
Using global variables with the TSEG is a bad idea because they are not relocated properly right now. Instead make the variables static and add accessor functions for the rest of SMM to use. At the same time drop the tcg/smi1 pointers as they are not setup or ever used. (the debug output is added back in a subsequent commit) Change-Id: If0b2d47df4e482ead71bf713c1ef748da840073b Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1764 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2012-11-14SMM: Extract function for finding save state nodeDuncan Laurie
This is currently used by the ELOG GSMI interface but is a good way to pass data to SMM so move the current searching code to a separate function and make it a bit more versatile with the checks it does to find a match so it can be used in other situations.

2012-11-14SMM: Restore GNVS pointer in the resume pathDuncan Laurie
The SMM GNVS pointer is normally updated only when the ACPI tables are created, which does not happen in the resume path. In order to restore this pointer it needs to be available at resume time. The method used to locate it at creation time cannot be used again as that magic signature is overwritten with the address itself. So a new CBMEM ID is added to store the 32bit address so it can be found again easily. A new function is defined to save this pointer in CBMEM which needs to be called when the ACPI tables are created in each mainboard when write_acpi_tables() is called. The cpu_index variable had to be renamed due to a conflict when cpu/cpu.h is added for the smm_setup_structures() prototype.

Right now coreboot's build process produces images that are not booting on actual hardware because they are smaller than the actual flash device and also don't have an IFD nor an ME firmware in them. In order to produce bootable images, you needed a wrapper script / extra step until now. With this change, the resulting coreboot.rom is actually bootable.

2012-11-12SPI: Add early romstage SPI driver using hardware sequencingDuncan Laurie
This is a basic romstage driver that can be used for the MRC cache code on systems where we do not have the MRC cache stored in a flash region that is memory mapped. It uses the hardware sequencing interface to avoid having to know anything about the flash chip itself. BUG=chrome-os-partner:15031 BRANCH=stout TEST=manual: this was tested with debug code added to romstage that attempted to read the MRC cache at offset 0x3e0000.

2012-11-12SPI: Fix and enable Fast Read supportDuncan Laurie
- Fix handling of 5-byte Fast Read command in the ICH SPI driver. This fix is ported from the U-boot driver. - Allow CONFIG_SPI_FLASH_NO_FAST_READ to be overridden by defining a name for the bool in Kconfig and removing the forced select in southbridge config - Fix use of CONFIG_SPI_FLASH_NO_FAST_READ in SPI drivers to use #if instead of #ifdef - Relocate flash functions in SMM so they are usable. This really only needs to happen for read function pointer since it uses a global function rather than a static one from the chip, but it is good to ensure the rest are set up correctly as well.

Right now the SPI bus is getting set to 20mhz for transactions initiated with the software sequence interface. In order to be able to do reasonable fastread/write/erase we can bump this up to a higher value at boot before it gets locked at 20mhz. To do this read out the speed set in the SPI descriptor for hardware sequencing and apply it to software sequencing.
