2013-02-04exynos5250: make lowlevel_init_c.c benignDavid Hendricks
This file has mostly (but not entirely) been replaced by coreboot stage files. We'll keep it around for a bit longer as a reference, but in the meantime we'll stop compiling it as to avoid comptilation issues as we change other parts of the code.

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.

Examples of this typically include board straps which are used to provide mainboard-specific information at the hardware- level, such as board revision or configuration options.

2013-02-03armv7: Add 'bootblock' build class.Hung-Te Lin
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.)

2013-01-31Improve how our printk calls do_div by using constants.Ronald G. Minnich
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.

This lays out the groundwork for using a proper bootblock on ARM. Currently we bypass the bootblock entirely and go straight to romstage. However we want to utilize CBFS to maximize flexibility of placing code without relying on a lot of magic numbers which will break depending on the SoC in use.

2013-01-12Implement GCC code coverage analysisStefan Reinauer
In order to provide some insight on what code is executed during coreboot's run time and how well our test scenarios work, this adds code coverage support to coreboot's ram stage. This should be easily adaptable for payloads, and maybe even romstage. See http://gcc.gnu.org/onlinedocs/gcc/Gcov.html for more information. To instrument coreboot, select CONFIG_COVERAGE ("Code coverage support") in Kconfig, and recompile coreboot. coreboot will then store its code coverage information into CBMEM, if possible. Then, run "cbmem -CV" as root on the target system running the instrumented coreboot binary. This will create a whole bunch of .gcda files that contain coverage information. Tar them up, copy them to your build system machine, and untar them. Then you can use your favorite coverage utility (gcov, lcov, ...) to visualize code coverage. For a sneak peak of what will expect you, please take a look at http://www.coreboot.org/~stepan/coreboot-coverage/ Change-Id: Ib287d8309878a1f5c4be770c38b1bc0bb3aa6ec7 Signed-off-by: Stefan Reinauer <reinauer@google.com> Reviewed-on: http://review.coreboot.org/2052 Tested-by: build bot (Jenkins) Reviewed-by: David Hendricks <dhendrix@chromium.org> Reviewed-by: Martin Roth <martin@se-eng.com> Reviewed-by: Ronald G.

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.
