2013-01-30Exynos5250: Get DDR3 working by changing what is compiled and add a functionRonald G. Minnich
This is a minor set of changes to get DDR3 going. Move compilation of DDR3 startup to the romstage. Fix a prototype that was missing a void. Remove a function that is overly flexible, and even though it is overly flexible only actually can handle one type of RAM. Mainboards only support one type of DRAM, so create a function to explicitly initialize the type of DDR we have -- DDR3. With these changes, and the previous changes, google snow is ready to run the ramstage. Change-Id: I37e0ab0d2dbc1dd121fb175386a46bc2fb1285e5 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: add debug prints to DDR3 startup code.Ronald G. Minnich
It can be handy to have debug prints as DRAM is started up, so that in the case of failure (does that ever happen?) you've got some idea where it failed. This patch adds some DEBUG_SPEW prints to the DDR3 code. I am doing this as its own CL because we may find we want to revert it. That's unlikely but it is not impossible if we skew the timing in some way. This code works for some trivial DRAM tests. Change-Id: I57e8d2a2d8df6b8ec8cd0d414681fc513e9999e3 Signed-off-by: Ronald G.

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.

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.

2013-01-10Fix 2 infinite loops if IMC doesn't respondMartin Roth
ACPI code: The ACPI code is not currently being compiled in by default, but assuming that it will be at some point, I'm fixing the loop that waits for the IMC to respond after sending it a command. The loop now exits after 500ms, similar to the function in agesa. Agesa Code: a 16 bit variable will always be less than 100000. Change to be a 32 bit variable.

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.

I removed the hard float support because it got errors and coreboot should never use floats anyway. We're still having trouble with enums but I want to see how far it gets with this patch. Also, put the flags in a form that makes diffs easier to read. It's almost impossible otherwise. Finally, move some flags to the architecture Makefile, and rely on the fact that some are set for all architectures.
