2012-03-31Add support for RAM-less multi-processor initKyösti Mälkki
For a hyper-threading processor, enabling cache requires that both the BSP and AP CPU clear CR0.CD (Cache Disable) bit. For a Cache-As-Ram implementation, partial multi-processor initialisation precedes raminit and AP CPUs' 16bit entry must be run from ROM. The AP CPU can only start execute real-mode code at a 4kB aligned address below 1MB. The protected mode entry code for AP is identical with the BSP code, which is already located at the top of bootblock. This patch takes the simplest approach and aligns the bootblock 16 bit entry at highest possible 4kB boundary below 1MB. The symbol ap_sipi_vector is tested to match CONFIG_AP_SIPI_VECTOR used by the CAR code in romstage. Adress is not expected to ever change, but if it does, link will fail.

2012-03-30MTRR: add alternate allocation method for odd memory mapsDuncan Laurie
With >= 4GB memory installed we get a memory map split in the middle due to remap that has boundaries that are inconveniently aligned for MTRRs due to the various UMA regions. 0000MB-2780MB 2780MB RAM (writeback) 2780MB-2782MB 2MB TSEG (uncached/SMRR) 2782MB-2784MB 2MB GFX GTT (uncached) 2784MB-2816MB 32MB GFX UMA (uncached) 2816MB-4096MB 1280MB EMPTY (N/A) 4096MB-5368MB 1272MB RAM (writeback) 5368MB-5376MB 8MB ME UMA (uncached) The default MTRR allocation method of trying to cover everything with one MTRR and then carve out a single uncached region does not work for the GPU aperture which needs write-combining type, and it also has issues trying to cover the uneven boundaries in the avaiable variable MTRRs. My goal was to make a minimal set of changes and avoid modifying behavior on existing systems with an algorithm that is not always optimal for a typical memory layout. So the flag 'above4gb=2' will change these allocation behaviors: 1) Detect the number of available variable MTRRs rather than limiting to hardcoded value. We need every last MTRR. 2) Don't try to cover all RAM with one MTRR, instead let each RAM region get covered independently. 3) Don't assume uma_memory_base is part of the last region and increase the size of that region. In this case the UMA region is carved out from the lower memory region and it is already declared as part of the ram region. 4) If a memory region can't be covered with MTRRs >= 16MB then instead make a larger region and trim it with uncached MTRRs.

2012-03-30Prepare the BIOS data areas before device init.Duncan Laurie
Since we do not run option roms in normal mode nothing was initializing the BDA/EBDA and yet Linux depends very much on it having sane values here. For the most part the kernel tries to work around this not being initialized, but every once in awhile (1/300 boots or so) it would end up reading something that looked sane from BDA but was not and then it would panic. In this change the EBDA is unconditionally setup before devices are initialized. I'm not set on the location in dev_initialize() but there does not seem to be another place to hook it in so that it runs just once for ALL platforms regardless of whether they use option roms or not. (possibly hardwaremain?) The EBDA setup code has been moved into its own location in arch/x86/lib/ebda.c so it can be compiled in even if the option rom code is not. The low memory size is still set to 1MB which is enough to make linux happy without having to hook into each mainboard to get a more appropriate value. The setup_ebda() function takes inputs so it could be changed for a mainboard if needed. OLD/BROKEN would read garbage. Examples from different boots: ebda_addr=0x75e80 lowmem=0x1553400 ebda_addr=0x5e080 lowmem=0x3e51400 ebda_addr=0x7aa80 lowmem=0x2f8a800 NEW/FIXED now reads consistent values: ebda_addr=0xf6000 lowmem=0x100000 Change-Id: I6cb79f0e3e43cc65f7e5fe98b6cad1a557ccd949 Signed-off-by: Duncan Laurie <dlaurie@google.com> Reviewed-on: http://review.coreboot.org/769 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2012-03-29Add support for enabling PCIe Common Clock and ASPMDuncan Laurie
These are guarded by individual Kconfig entries. The deprecated CONFIG_PCIE_TUNING defines have been removed in favor of using specific config options. This is the generic half, there is board-specific pieces still to come that tune before and after ASPM is enabled.

2012-03-29Refactor publishing CBMEM addresses through coreboot table.Vadim Bendebury
We need to provide u-boot access to several different CBMEM sections. To do that, a common coreboot table structure is used, just different tags match different coreboot table sections. Also, the code is added to export CBMEM console and MRC cache addresses through the same mechanism.

2012-03-29Add timestamp table pointer to the coreboot table.Vadim Bendebury
This change exports the timestamp table pointer through coreboot table to make it possible for u-boot to add timestamps to the table. Inclusion of cbmem.h allows to drop external declarations in coreboot_table.c.

2012-03-29Introduce utility for parsing CBMEM contents.Vadim Bendebury
This is a python script which is supposed to run on a target which is controlled by coreboot. The script examines top of memory looking for the CBMEM signature at addresses aligned at 128K boundary. Once the script finds the CBMEM, it iterates through the CBMEM table of contents and parses two entries: the timestamps and the console log. This submission is just a template to build upon to create a utility for displaying CBMEM information while running Linux on the target.

2012-03-29CBMEM CONSOLE: Add CBMEM console driver implementation.Vadim Bendebury
The CBMEM console driver saves console output in a CBMEM area, which then is made available to Linux applications for perusing. There are some system limitations which need to be worked around to achieve this goal: - some console traffic is generated before DRAM is initialized, leave alone CBMEM initialized. - after the RAM based stage starts, a lot of traffic is generated before CBMEM is initialized. As a result, the console log lives in three different places - the bottom of the cache as RAM space, the CBMEM buffer (where it is expected to be) and a static buffer used early in the RAM stage. When execution starts (in the cache as RAM mode), the console buffer is allocated at the bottom of the cache as RAM memory address range. Once DRAM is initialized, the CBMEM structure is initialized, and then the console buffer contents are copied from the bottom of the cache as RAM space into the CBMEM area right before the cache as RAM mode is disabled. The src/lib/cbmem_console.c:cbmemc_reinit() takes care of the copying. At this point the cache as RAM memory is about to be disabled, but the ROM stage is still going generating console output. To make sure this output is not lost, cbmemc_reinit() saves the new buffer address at a fixed location (0x600 was chosen for this), and the actual "printing" function checks to see if the RAM is already initialized (the stack is in RAM), and if so, gets the console buffer pointer from this location instead of using the cache as RAM address. When the RAM stage starts, a static buffer is used to store the console output, as the CBMEM buffer location is not known. Then, when CBMEM is reinitialized, cbmemc_reinit() again takes care of the copying. In case the allocated buffers are not large enough, the excessive data is dropped, and the copying routine adds some text to the output buffer to indicate that there has been data lost and how many characters were dropped.
