2012-11-27Drop duplicate files that prevent building without ramstage.aStefan Reinauer
When dropping ramstage.a duplicate symbols in ramstage will start breaking the build. Hence drop all the duplicate functions implemented by mainboards that have those functions in generic or component code already.

2012-11-27build system: Eliminate special case for c_startPatrick Georgi
c_start.o has a special case in the build system, which we can eliminate, somewhat simplifying the build. To ensure that the entry point is at the beginning, introduce a new section .textfirst that is placed appropriately. In principle the ENTRY() definition in the linker script should be enough, but better be safe.

2012-11-27Get rid of drivers classPatrick Georgi
The use of ramstage.a required the build system to handle some object files in a special way, which were put in the drivers class. These object files didn't provide any symbols that were used directly (but only via linker magic), and so the linker never considered them for inclusion. With ramstage.a gone, we can drop this special class, too.

2012-11-27Drop ramstage.aPatrick Georgi
ramstage.a has two issues: 1. duplicate source filenames don't survive the ar(1) treatment properly (so files aren't considered) 2. ld doesn't resolve symbols if it isn't forced to, in particular no overrides of weak symbols Downside: The resulting binaries get slightly larger. Link time optimizations should fix that, as would tighter rules in the build system (to not compile unused code in the first place).

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.

Also, the stack is poisoned, which is a good way to catch programming errors -- code should never count on auto variables being zerod. The stack bases are recorded in a new array, stacks. At the end, when all APs are initialized, the stacks are walked and the lowest level of the stack that is reached is printed. Build and boot and look for output like this: CPU1: stack allocated from 00148000 to 00148ff4:\ lowest stack address was 00148c4c CPU2: stack allocated from 00147000 to 00147ff4:\ lowest stack address was 00147c4c CPU3: stack allocated from 00146000 to 00146ff4:\ lowest stack address was 00146c4c Note that we used only about 1K of stack, even though in this case we allocated 4K (and in the main branch, we allocate 32K!)

2012-11-12ELOG: Support for non-memory mapped flashDuncan Laurie
If the event log is stored in flash that is not memory mapped then it must use the SPI controller to read from the flash device instead of relying on memory accesses. In addition a new CBMEM ID is added to keep an resident copy of the ELOG around if needed. The use of CBMEM for this is guarded by a new CONFIG_ELOG_CBMEM config option. This CBMEM buffer is created and filled late in the process when the SMBIOS table is being created because CBMEM is not functional when ELOG is first initialized. The downside to using CBMEM is that events added via the SMI handler at runtime are not reflected in the CBMEM copy because I don't want to let the SMM handler write to memory outside the TSEG region. In reality the only time we add runtime events is at kernel shutdown so the impact is limited. Test: 1) Test with CONFIG_ELOG_CBMEM enabled to ensure the event log is operational and SMBIOS points to address in CBMEM. The test should involve at least on reboot to ensure that the kernel is able to write events as well. > mosys -l smbios info log | grep ^address address | 0xacedd000 > mosys eventlog list 0 | 2012-10-10 14:02:46 | Log area cleared | 4096 1 | 2012-10-10 14:02:46 | System boot | 478 2 | 2012-10-10 14:02:46 | System Reset 3 | 2012-10-10 14:03:33 | Kernel Event | Clean Shutdown 4 | 2012-10-10 14:03:34 | System boot | 479 5 | 2012-10-10 14:03:34 | System Reset 2) Test with CONFIG_ELOG_CBMEM disabled to ensure the event log is operational and SMBIOS points to memory mapped flash.

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.

2012-11-12SPI: Configure Software Sequence SPI Freq to match descriptorDuncan Laurie
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.

2012-11-12oprom: Ensure that mode information is valid before putting it in the tables.Gabe Black
At least when CONFIG_CHROMEOS is turned on, it's possible for CONFIG_FRAMEBUFFER_KEEP_VESA_MODE to be set but for there not to be any valid information to put into the framebuffer coreboot table. That means that what's put in there is junk, probably all zeroes from the uninitialized global variable the mode information is stored in (mode_info). When a payload uses libpayload and turns on the coreboot framebuffer console, that console will attempt to scroll at some point and decrease the cursor's y coordinate until it is less than the number of rows claimed by the console. The number of rows is computed by taking the vertical resolution of the framebuffer and dividing it by the height of the font. Because the mode information was all zeroes, the coreboot table info is all zeroes, and that means that the number of rows the console claims is zero. You can't get the unsigned y coordinate of the cursor to be less than zero, so libpayload gets stuck in an infinite loop. The solution this change implements is to add a new function, vbe_mode_info_valid, which simply returns whether or not mode_info has anything in it. If not, the framebuffer coreboot table is not created, and libpayload doesn't get stuck.
