2013-02-25AMD Southbridge: Add RTC init to lpc_initMike Loptien
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. By setting the Date Alarm register to 0x00, it does not get evaluated along with the seconds, minutes, and hours when running 'fwts s3'. Information about fwts (Firmware Test Suite) can be found here: https://wiki.ubuntu.com/Kernel/Reference/fwts This is the same edit made to the CIMX SB800 titled 'AMD/Persimmon: Add RTC init to CIMX SB800' with commit ID: c4d3d which can be viewed here: http://review.coreboot.org/#/c/2488/ Change-Id: Iddb7a3cbabe736b511cde03d7dc0a4a0b1c7fd90 Signed-off-by: Mike Loptien <mike.loptien@se-eng.com> Reviewed-on: http://review.coreboot.org/2510 Reviewed-by: Martin Roth <martin.roth@se-eng.com> Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org> Tested-by: build bot (Jenkins) Reviewed-by: Dave Frodin <dave.frodin@se-eng.com>

Currently the size of the volatile storage for S3 reserved in the image is hardcoded to 32768 bytes. Make that configurable by introducing the Kconfig 'S3_DATA_SIZE'.

There was already a special case for the SPI base address in lpc_set_resources for southbridge/amd/cimx/sb800 and southbridge/amd/agesa/hudson, but it needed to be modified to keep from killing the IMC rom during initialization. As soon as the BAR is disabled by setting the new base address, the IMC dies. The fix is to make sure it's still enabled when setting the new base address instead of setting the new address then re-enabling it. Change the name SPIROM_BASE_ADDRESS to SPIROM_BASE_ADDRESS_REGISTER to more accurately describe what we're using.

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: 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.

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.

2012-07-26ELOG: Support GSMI in CPT/PPT southbridge SMI handlerDuncan Laurie
In order to support the GSMI interface the SMI handler needs to find and use the state save area from the same CPU that initiated the SMI. In this case it is a synchronous SMI resulting form an IO write to port 0xB2. To find the right CPU state save area iterate over the region until the "IO Misc Info" field reports the expected value and then proceed to use that state save area. This is needed because the coreboot SMI handler only executes on one core, and that core is non-deterministic. It is likely that the core executing the C SMM handler is not the same one that actually did the IO write to 0xB2 and generated the SMI. The GSMI parameter buffer is passed as a pointer to EBX in the tate save area, and the GSMI command is extracted from EAX before it is used as the return value. This interface is tested by enabling CONFIG_GOOGLE_GSMI in the kernel and generating events and verifying that they end up in the event log. 159 | 2012-06-23 16:22:45 | Kernl Event | Clean Shutdown 184 | 2012-06-23 17:14:05 | Kernl Event | Oops 185 | 2012-06-23 17:14:05 | Kernl Event | Panic Change-Id: Ic121ea69e9f50c88467c435e095c3e3629989806 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1317 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2012-07-24CPU: Set flex ratio to nominal TDP ratio in bootblockDuncan Laurie
CPUs with configurable TDP will run the TSC at the max non-turbo ratio for the maximum TDP value, which can cause issues if another TDP is desired. To deal with this we set the flex ratio to the nominal TDP ratio early in the boot and then configure the Soft Reset Data registers so the PCH can tell the CPU what frequency to run at after a reset. This is done very early in the bootblock because it is necessary to reset the system after setting a flex ratio. The end result is that the TSC will now increment at the max non-turbo frequency for the nominal TDP. On some system with 1.8GHz CPU ensure that the kernel detects the CPU speed as ~1800mhz rather than ~2300mhz: > dmesg | grep "MHz processor" [ 0.004000] Detected 1795.801 MHz processor.
