2013-02-26Revert "AMD S3: Program the flash in a bigger data packet"Dave Frodin
This reverts commit ca6e1f6c04c96c435bdbf30a1b88cab0e5be330b. The packet size changes ends up corrupting the flash when booting Persimmon. I did figure out that the maximum number of bytes that can be sent is actually 8 bytes according to the sb800 spec. There must be additional problems beyond that since setting the packet size to 8 still causes problems.

2013-02-21AMD S3: Introduce Kconfig variable 'S3_DATA_SIZE'Zheng Bao
Currently the size of the volatile storage for S3 reserved in the image is hardcoded to 32768 bytes. Make that configurable by introducing the Kconfig 'S3_DATA_SIZE'. As the storage space is needed for storing non-volatile, volatile and MTRR data, add a check if the size is big enough.

2013-02-20ARMV7: minor tweaks to inter-stage calling and payload handling.Ronald G. Minnich
Payloads, by design, can return. There's lots of mechanism in the payload code to support it, and the chooser payload relies on it. Hence, we should not mark the function call in exit_stage as noreturn. Not all ARM have unified caches, and it's not always easy to tell what to do. So we are very paranoid. Before we call between stages, we should carefully flush the dcache to memory and invalidate the icache. This may be more than is necessary on all architectures but it doesn't really hurt for the most part. So compile cache management code into all stages, and call the flush dcache/invalidate icache from all stages. Change-Id: Ib9cc625c4dfd2d7d4b3c69a74686cc655a9d6484 Signed-off-by: Ronald G.

2013-02-08console: Revise serial console configuration names.Hung-Te Lin
The console drivers (especially serial drivers) in Kconfig were named in different styles. This change will rename configuration names to a better naming style. - EARLY_CONSOLE: Enable output in pre-ram stage. (Renamed from EARLY_SERIAL_CONSOLE because it also supports non-serial) - CONSOLE_SERIAL: Enable serial output console, from one of the serial drivers. (Renamed from SERIAL_CONSOLE because other non-serial drivers are named as CONSOLE_XXX like CONSOLE_CBMEM) - CONSOLE_SERIAL_UART: Device-specific UART driver. (Renamed from CONSOLE_SERIAL_NONSTANDARD_MEM because it may be not memory-mapped) - HAVE_UART_SPECIAL: A dependency for CONSOLE_SERIAL_UART. Verified to boot on x86/qemu and armv7/snow, and still seeing console messages in romstage for both platforms.

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>

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.

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.

2013-01-04make early serial console support more genericDavid Hendricks
This patch makes pre-RAM serial init more generic, particularly for platforms which do not necessarily need cache-as-RAM in order to use the serial console and do not have a standard 8250 serial port. This adds a Kconfig variable to set romstage-* for very early serial console init. The current method assumes that cache-as-RAM should enable this, so to maintain compatibility selecting CACHE_AS_RAM will also select EARLY_SERIAL_CONSOLE. The UART code structure needs some rework, but the use of ROMCC, romstage, and then ramstage makes things complex. uart.h now includes all .h files for all uarts. All 2 of them. This is actually a simplifying change. Change-Id: I089e7af633c227baf3c06c685f005e9d0e4b38ce Signed-off-by: David Hendricks <dhendrix@chromium.org> Signed-off-by: Ronald G.

2012-12-12Claim the SPI bus before writes if the IMC ROM is presentMartin Roth
The SB800 and Hudson now support adding the IMC ROM which runs from the same chip as coreboot. When the IMC is running, write or erase commands sent to the spi bus will fail, and the IMC will die. To fix this, we send a request to the IMC to stop fetching from the SPI rom while we write to it. This process (in one form or another) is required for writes to the SPI bus while the IMC is running. Because the IMC can take up to 500ms to respond every time we claim the bus, this patch tries to keep the number of times we need to do that to a minimum. We only need to claim the bus on writes, and using a counter for the semaphore allows us to call in once to claim the bus at the beginning of a number of transactions and it will stay claimed until we release it at the end of the transactions. Claim() - takes up to 500ms hit claim() - no delay erase() release() claim() - no delay write() release() Release() Change-Id: I4e003c5122a2ed47abce57ab8b92dee6aa4713ed Signed-off-by: Martin Roth <martin@se-eng.com> Reviewed-on: http://review.coreboot.org/1976 Tested-by: build bot (Jenkins) Reviewed-by: Patrick Georgi <patrick@georgi-clan.de>
