2013-02-11Supermicro H8QGI: Substract 1 from MMCONF range limitKonstantin Aladyshev
MMCONF space is defined by two config parameters: MMCONF_BASE_ADDRESS (0xF800 0000) MMCONF_BUS_NUMBER (64) Coreboot allocates 1MB per bus, so MMCONF limit should be: 0xF800 0000 + 64*(0x0010 0000) - 1 = 0xFBFF FFFF Current code does not have (-1) component, this makes MMCONF limit equal 0xFC00 FFFF. Not 0xFC00 0000, because according to BKDG lower two bytes of MMIO limit always equal 0xFFFF: MMIOLimit = {MMIOLimitRegister[47:16], FFFFh}. Add (-1) to correct this issue. No functionality change has been experienced. The five times slower RAM speed compared to the proprietary vendor BIOS still remains.

2013-02-11AMD SB900: fix warningsMartin Roth
Add a prototype to a .h file Remove an unused file (GppHp.c) from the build by deleting it from the makefile. I left the file since this is vendorcode. This is the code for PCIe hotplug. Inside GppHp.c, make functions not called from outside static. This obviously isn't important since the file isn't used, but for the sake of the cleanup I thought I'd go ahead with it... This was tested with the torpedo build.

2013-02-11armv7/exynos5250/snow: deprecate CONFIG_{RAMBASE,RAMTOP}David Hendricks
RAMBASE and RAMTOP are leftovers from the x86 port and do not apply the same way on ARM platforms. On x86 they refer to the low memory region where coreboot tables reside. However on ARM we don't have such a region which is architecturally defined. So instead we'll use the CPU-defined DRAM base address and the mainboard-defined DRAM size. This also has the pleasant side-effect of fixing the coreboot tables to not clobber ramstage code...

The common part of the bootblock resets the nvram data if it's found to be invalid. Since that code is compiled with romcc in i386 mode, there's a shortage on registers. Try to reduce the strain by doing things smarter: cmos_write_inner is the same as cmos_write, just that it doesn't check if the RTC is disabled.

2013-02-06exynos/snow: Move core/memory clock-related and board ID codeDavid Hendricks
This patch moves ARM core and DRAM timing functions around to simplify the dependencies for system_clock_init(). The original code was architected such that the system_clock_init() function called other functions to obtain core and memory timings. Due to the way memory timing information must be obtained on Snow, which entails decoding platform-specific board straps, the bottom- up approach resulted in having the low-level clock init code implicitly depend on board and vendor-specific info: main() ->system_clock_init() -> get_arm_ratios() -> CPU-specific code -> clock_get_mem_timings() -> board_get_revision() -> read GPIOs (3-state logic) -> Decode GPIOs in a vendor-specific manner -> Choose memory timings from module-specific look-up table ...then proceed to init clocks ...come back to main() The new approach gathers all board and vendor-specific info in a more appropriate location and passes it into system_clock_init(): main() -> get_arm_ratios() -> CPU-specific code -> get_mem_timings() -> board_get_config() -> read GPIOs (3-state logic) -> Decode GPIOs in a vendor-specific manner -> Choose memory timings from module-specific look-up table -> system_clock_init() ...back to main() Change-Id: Ie237ebff76fc2d8a4d2f4577a226ac3909e4d4e8 Signed-off-by: David Hendricks <dhendrix@chromium.org> Reviewed-on: http://review.coreboot.org/2271 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>

2013-02-04exynos/snow: get rid of board-specific arbitration codeDavid Hendricks
Snow's AP, EC, PMU, and smarty battery share a bus. Both the AP and EC can act as a master, so to avoid conflicts an arbitration mechanism consisting of two GPIOs is used. By default, the AP "owns" the bus unless it is off (in which case the EC doesn't monitor the arbitration pins). This means the boot firmware does not need to worry about these lines. The payload may if it needs to communicate with the EC, though. In any case, board-specific bus arbitration logic does not belong in a low-level driver that is supposed to be generic for an entire CPU family. If the payload needs to talk to the EC, we'll deal with it there.

For ARM platform, the bootblock may need more C source files to initialize UART / SPI for loading romstage. To preventing making complex and implicit dependency by using #include inside bootblock.c, we should add a new build class "bootblock". Also #ifdef __BOOT_BLOCK__ can be used to detect if the source is being compiled for boot block. For x86, the bootblock is limited to fewer assembly files so it's not using this class. (Some files shared by x86 and arm in top level or lib are also changed but nothing should be changed in x86 build process.)

The do_div code has a nice optimization in it when it is called with constants. The current highly generalized use of it defeats those optimizations and causes trouble on ARM, resulting in a complex and buggy code path. Since we only need to print in bases 8, 10, and 16, do a minor restructuring of the code so that we call do_div with constants. If you need base 2, print in base 16 and do it in your head. :-) This fixes an ongoing problem with ARM, will not harm X86, and will help PPC should we ever want to support it again. Plus, I don't have to ever try to understand the div64 assembly and where it's going wrong :-) Change-Id: I6a480011916eb0834e05c5bb10909d83330fe797 Signed-off-by: Ronald G.

2013-01-30Extend CBFS to support arbitrary ROM source media.Hung-Te Lin
Summary: Isolate CBFS underlying I/O to board/arch-specific implementations as "media stream", to allow loading and booting romstage on non-x86. CBFS functions now all take a new "media source" parameter; use CBFS_DEFAULT_MEDIA if you simply want to load from main firmware. API Changes: cbfs_find => cbfs_get_file. cbfs_find_file => cbfs_get_file_content. cbfs_get_file => cbfs_get_file_content with correct type. CBFS used to work only on memory-mapped ROM (all x86). For platforms like ARM, the ROM may come from USB, UART, or SPI -- any serial devices and not available for memory mapping. To support these devices (and allowing CBFS to read from multiple source at the same time), CBFS operations are now virtual-ized into "cbfs_media". To simplify porting existing code, every media source must support both "reading into pre-allocated memory (read)" and "read and return an allocated buffer (map)". For devices without native memory-mapped ROM, "cbfs_simple_buffer*" provides simple memory mapping simulation. Every CBFS function now takes a cbfs_media* as parameter. CBFS_DEFAULT_MEDIA is defined for CBFS functions to automatically initialize a per-board default media (CBFS will internally calls init_default_cbfs_media). Also revised CBFS function names relying on memory mapped backend (ex, "cbfs_find" => actually loads files). Now we only have two getters: struct cbfs_file *entry = cbfs_get_file(media, name); void *data = cbfs_get_file_content(CBFS_DEFAULT_MEDIA, name, type); Test results: - Verified to work on x86/qemu. - Compiles on ARM, and follow up commit will provide working SPI driver.

2013-01-29Exynos5250: make vendor enums in the timing array more debuggable.Ronald G. Minnich
The timing array is crucial to proper operation of DRAM. Getting a valid pointer to it is hence very important. Unfortunately, the constants chosen for the vendor were '1', and '2', (this in a 32-bit word) which in a debug print makes it almost impossible to tell if you've got a misaligned pointer. Note: coreboot people did not choose them :-) So, give them values which are extremely unlikely to occur elsewhere in the array (or in memory, for that matter). Given the frequency with which this check occurs, i.e. once, I would much prefer strings but I expect I'd get shouted down on that one. Constants in this case are an almost useless optimization but we'll go with them for now. Note no space is saved by not using strings: there's an entire function somewhere devoted to mapping the enum to a string! Debug prints of pointers to structs in this array are now far more useful than they were. See snarky comment in the code (left there to make sure nobody gets tempted to get fancy again). Comment now less snarky. This is tested on google snow to the point that the DRAM works. Change-Id: I30bc44719f321f791fd82ded60e29393399d9e3d Signed-off-by: Ronald G.
