2012-11-12Avoid using hardcoded values in MRC cache codeVadim Bendebury
The MRC cache code, as implemented, in some cases uses configuration settings for MRC cache region, and in some cases - the values read from FMAP. These do not necessarily match, the code should use FMAP across the board. This change also refactors mrccache.c to limit number of iterations through the cache area and number of fmap area searches.

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.

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.

- 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.

2012-11-12oprom: 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.

2012-11-12Utility to dump boot timing tableVadim Bendebury
Coreboot and u-boot create a table of timestamps which allows to see the boot process performance. The util/cbmem/cbmem.py script allows to access the table after ChromeOS boots up and display its contents on the console. The problem is that shipping images do not include Python interpreter, so there is no way to access the table on a production machine. This change introduces a utility which is a Linux app displaying the timestamp table. Conceivably the output of this utility might be included in one of the ChromeOS :/system sections, so it was attempted to write this procedure 'fail safe', namely reporting errors and not continuing processing if something goes wrong. Including of coreboot/src .h files will allow to keep the firmware timestamp implementation and this utility in sync in the future. Test: . build the utility (run 'make' while in chroot in util/cbmem) . copy `cbmem' and 'cbmem.py' to the target . run both utilities (limiting cbmem.py output to 25 lines or so) . observe that the generated tables are identical (modulo rounding up of int division, resulting in 1 ns discrepancies in some cases) localhost var # ./cbmem 18 entries total: 1:62,080 2:64,569 (2,489) 3:82,520 (17,951) 4:82,695 (174) 8:84,384 (1,688) 9:131,731 (47,347) 10:131,821 (89) 30:131,849 (27) 40:132,618 (769) 50:134,594 (1,975) 60:134,729 (134) 70:363,440 (228,710) 75:363,453 (13) 80:368,165 (4,711) 90:370,018 (1,852) 99:488,217 (118,199) 1000:491,324 (3,107) 1100:760,475 (269,150) localhost var # ./cbmem.py | head -25 time base 4249800, total entries 18 1:62,080 2:64,569 (2,489) 3:82,520 (17,951) 4:82,695 (174) 8:84,384 (1,688) 9:131,731 (47,347) 10:131,821 (89) 30:131,849 (27) 40:132,618 (769) 50:134,594 (1,975) 60:134,729 (134) 70:363,440 (228,710) 75:363,453 (13) 80:368,165 (4,711) 90:370,018 (1,852) 99:488,217 (118,199) 1000:491,324 (3,107) 1100:760,475 (269,150) Change-Id: I013e594d4afe323106d88e7938dd40b17760621c Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Reviewed-on: http://review.coreboot.org/1759 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>

2012-11-08RTC: Don't clear pending interrupt in resume pathDuncan Laurie
The linux kernel relies on the RTC reporting pending interrupts if the RTC alarm was used to wake the system. If we clear these flags here then the rtc-cmos driver in the kernel will think that no interrupts are pending and will not re-start the timerqueue to handle the alarm timerqueue node. This flag doesn't exist in SMM but the rtc code is compiled there. Since rtc_init() is not called by SMM it is guarded with an ifdef. I performed several thousand suspend/resume cycles without seeing an issue where hwclock was unable to read from /dev/rtc. There still is a potential kernel issue where the timerqueue can stall but this makes that much less likely to happen on resume.

If you call cbfstool like this: cbfstool coreboot.rom create 8192K bootblock.bin 64 0x700000 it will now create an 8M image with CBFS covering the last 1M of that image. Test: cbfstool coreboot.rom create 8192K bootblock.bin 64 0x700000 creates an 8M image that is 7M of 0xff and 1M of CBFS.

Until now, the MRC cache position and size was hard coded in Kconfig. However, on ChromeOS devices, it should be determined by reading the FMAP. This patch provides a minimalistic FMAP parser (libflashmap was too complex and OS centered) to allow reading the in-ROM flash map and look for sections. This will also be needed on some partner devices where coreboot will have to find the VPD in order to set up the device's mac address correctly. The MRC cache implementation demonstrates how to use the FMAP parser.

Now, all bridges and devices are trained on the device 0.0 enable. After PCIe init, the PCIe ports with devices are on and the PCIe ports without devices are off. so resources may be allocated correctly during the rest of the PCI scan. But if the devicetree was being used to enable/disable devices after initialization, the problems would arise. Take a look at the serial log: do_pci_scan_bridge for PCI: 00:02.0 PCI: pci_scan_bus for bus 01 PCI: pci_scan_bus returning with max=001 do_pci_scan_bridge returns max 1 do_pci_scan_bridge for PCI: 00:03.0 PCI: pci_scan_bus for bus 02 PCI: pci_scan_bus returning with max=002 do_pci_scan_bridge returns max 2 do_pci_scan_bridge for PCI: 00:04.0 PCI: pci_scan_bus for bus 03 PCI: pci_scan_bus returning with max=003 do_pci_scan_bridge returns max 3 PCI bridge 02.0, 03.0 and 04.0 are not inserted devices, but these bridges are still scanned.

There are four mainboards using agesa family15 code: Supermicro h8scm and h8qgi, Tyan s8226 and AMD dinar. All of these boards' PCI domain starts from 0x18.0. Take h8scm as an example, PCI devices from 0.0 to 0x14.5 is under 0x18.0. Now, the PCI domain's scan bus function stats from 0.0. This would result to the PCI devices be scanned twice. Because when the function run to device 18.0, it would scan from 0.0 again. This issue would result to 2 problems: 1) PCI device may be assigned two different PCI address. If this happenned on VGA device, coreboot maybe not load vga bios correctly. 2) coreboot initializes rd890's IO APIC twice. So this patch scans from 0x18.0 and could resolve the problems above.
