2011-10-13Reorder x86's post relocation memory layoutGabe Black
This changes the layout in decreasing addresses from: 1. Stack 2. Sections in the image 3. Heap to 1. Sections in the image 2. Heap 3. Stack This allows the stack to grow significantly more since it isn't constrained by the other u-boot areas. More importantly, the generic memory wipe code assumes that the stack is the lowest addressed area used by the main part of u-boot. In the original layout, that means that u-boot tramples all over itself. In the new layout, it works. BUG=chrome-os-partner:6194 BUG=chrome-os-partner:6195 TEST=Booted on Stumpy.

This way when that dram "banks" are displayed, there's some useful information there. The number of "banks" we claim to have needs to be adjusted so that it covers the number of RAM e820 regions we expect to have/care about. This needs to be done after "RAM" initialization even though we always run from RAM. The bd pointer in the global data structure doesn't automatically point to anything, and it isn't set up until "RAM" is available since, I assume, it would take too much space in the very constrained pre-RAM environment.

2011-10-03Process all cbmem table references consistently.Vadim Bendebury
A few CBMEM table entries are included in coreboot to let u-boot discover the locations of those entries. They all are passed using the same structure within coreboot table. This patch makes use of that structure for all communicated entries (timestam, console and MRC cache). It does not make sense to keep types of pointers in the sysinfo table, as nobody but the respective users of those fields use the types. Let's keep the pointers as void *, this also allows to reduce the amount of include files in systinfo.h and hide the timestamp structures in timestamp.c. BUG=chrome-os-partner:4200 TEST=manual . build the new firmware and program it on a stumpy . restart the machine . after it comes up to ChromeOS, run the cbmem.py utility Observe that timstamp values are displayed, and there is an entry with index 1000 (added by u-boot to the coreboot timestamp table).

2011-09-28Track whether u-boot was warm or cold booted, and implement is_processor_resetGabe Black
Code which determined whether u-boot on x86 was warm or cold booted (really if it started at the beginning of the text segment or at the ELF entry point) was partially implemented, and the result was simply dropped when leaving the assembly part of initialization. This change completes the implementation, plumbs the result through to the global data structure, and implements is_processor_reset to check the value there. BUG=chrome-os-partner:5252 TEST=Built and did a twostop boot on Alex. The firmware was resigned using the command below so that the RW firmware would be used. When is_processor_reset was hardcoded to return true all the time, u-boot would go into recovery mode.

2011-09-26Enable coreboot timestamp facility support in u-boot.Vadim Bendebury
This change turns on the code which allows u-boot to add timestamps to the timestamp table created by coreboot. Since u-boot does not use the tsc_t like structure to represent HW counter readings, this structure is being replaced by 64 bit integer. The timestamp_init() function is now initializing the base timer value used by u-boot to calculate the HW counter increments. Timestamp facility is initialized as soon as the timestamp table pointer is found in the coreboot table. The u-boot generated timer events' ID will start at 1000 to clearly separate u-boot events from coreboot events in the timer trace. BUG=chromium-os:20733 TEST=manual A Python script was used to retrieve the CBMEM timestamp table while running CromeOS. The script will later be submitted into the ChromeOS tools directory. The following output was generated by the script: localhost ~ # /var/vbendeb/cbmem.py id 1, value 804,824,023 id 2, value 7,846,816,530 id 1000, value 19,356,528,758 Change-Id: I48c46e7b5cd2b2601d12465e0d8946152f31126e Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Reviewed-on: http://gerrit.chromium.org/gerrit/8274 Reviewed-by: Stefan Reinauer <reinauer@google.com>
