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.

2013-01-12Implement 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.

As we move to supporting other systems we need to get rid of assembly where we can. The log2 function in src/lib is identical to the assembly one (tested for all 32-bit signed integers :-) and takes about 10 ns to run as opposed to 5ns for the non-portable assembly version. While speed is good, I think we can spare the 15 ns or so we add to boot time by using the C version only. Change-Id: Icafa565eae282c85fa5fc01b3bd1f110cd9aaa91 Signed-off-by: Ronald G.

- Optionally override FSB clock detection in generic LAPIC code with constant value. - Override on AMD Model fxx, 10xxx, agesa CPUs with 200MHz - compile LAPIC code for romstage, too - Remove #include ".../apic_timer.c" in AMD based mainboards - Remove custom udelay implementation from intel northbridges' romstages Future work: - remove the compile time special case (requires some cpuid based switching) - drop northbridge udelay implementations (i945, i5000) if not required anymore (eg. can SMM use the LAPIC timer?)

c_start.o has a special case in the build system, which we can eliminate, somewhat simplifying the build. To ensure that the entry point is at the beginning, introduce a new section .textfirst that is placed appropriately. In principle the ENTRY() definition in the linker script should be enough, but better be safe.

2012-11-27Get rid of drivers classPatrick Georgi
The use of ramstage.a required the build system to handle some object files in a special way, which were put in the drivers class. These object files didn't provide any symbols that were used directly (but only via linker magic), and so the linker never considered them for inclusion. With ramstage.a gone, we can drop this special class, too.

2012-11-27Drop ramstage.aPatrick Georgi
ramstage.a has two issues: 1. duplicate source filenames don't survive the ar(1) treatment properly (so files aren't considered) 2. ld doesn't resolve symbols if it isn't forced to, in particular no overrides of weak symbols Downside: The resulting binaries get slightly larger. Link time optimizations should fix that, as would tighter rules in the build system (to not compile unused code in the first place).

2012-11-14SMM: Restore GNVS pointer in the resume pathDuncan Laurie
The SMM GNVS pointer is normally updated only when the ACPI tables are created, which does not happen in the resume path. In order to restore this pointer it needs to be available at resume time. The method used to locate it at creation time cannot be used again as that magic signature is overwritten with the address itself. So a new CBMEM ID is added to store the 32bit address so it can be found again easily. A new function is defined to save this pointer in CBMEM which needs to be called when the ACPI tables are created in each mainboard when write_acpi_tables() is called. The cpu_index variable had to be renamed due to a conflict when cpu/cpu.h is added for the smm_setup_structures() prototype.

2012-11-13Pass the CPU index as a parameter to startup.Ronald G. Minnich
This addition is in support of future multicore support in coreboot. It also will allow us to remove some asssembly code. The CPU "index" -- i.e., its order in the sequence in which cores are brought up, NOT its APIC id -- is passed into the secondary start. We modify the function to specify regparm(0). We also take this opportunity to do some cleanup: indexes become unsigned ints, not unsigned longs, for example. Build and boot on a multicore system, with pcserial enabled. Capture the output. Observe that the messages Initializing CPU #0 Initializing CPU #1 Initializing CPU #2 Initializing CPU #3 appear exactly as they do prior to this change.
