2013-02-14sconfig: rename pci_domain -> domainStefan Reinauer
The name pci_domain was a bit misleading, since the construct is only PCI specific in a particular (northbridge/cpu) implementation, but not by concept. As implementations and hardware change, be more generic about our naming. This will allow us to support non-PCI systems without adding new keywords.

2013-02-11crossgcc: Support hosts using non-GNU make as default make.Hung-Te Lin
On hosts using non-GNU make as default make program (ex, FreeBSD's default is BSD make and having GNU make as "gmake"), building acpica will fail. We should use the correct path of make $(MAKE). Verified to build on FreeBSD 9.0 with gcc 4.7 from ports. Note, the shipped gcc in FreeBSD 9.0 is 4.2.1 and needs more patches to remove -Wbad-function-case and -Wempty-body. That should be fixed in a future patch.

2013-02-06cbfstool: Add support for 64bit UEFIStefan Reinauer
Right now cbfstool only accepts firmware volumes with a x86 SEC core and refuses an x86-64 SEC core because some magic values and the extended PE header are different. With this patch, both IA32/x64 images are supported. (No check is done whether the mainboard actually supports 64bit CPUs, so careful!) This needs another patch to Tiano Core that switches to long mode after jumping to the 64bit entry point. Right now that code assumes we're already in 64bit code and the machine crashes.

Current cbfstool implementation is relying on global variables to pass processed data, and the calculation of address is based on x86 architecture (ex, always assuming 0x0000 as invalid address), not easy to be used on platforms without top-aligned memory mapping. This CL is a first step to start a new cbfstool without global variables, and to prevent assuming memory layout in x86 mode. The first published APIs are for reading and writing existing CBFS ROM image files (and to find file entries in a ROM file). Read cbfs_image.h for detail usage of each API function.

2013-02-05cbfstool: Add buffer management API.Hung-Te Lin
Many functions in cbfstool need to deal with a memory buffer - both location and size. Right now it's made by different ways: for ROM image using global variable (romsize, master_header); and in cbfs-* using return value for size and char** to return memory location. This may cause bugs like assuming incorrect return types, ex: uint32_t file_size = parse(); // which returns "-1" on error if (file_size <= 0) { ... And the parse error will never be caught. We can simplify this by introducing a buffer API, to change unsigned int do_something(char *input, size_t len, char **output, ...) into int do_something(struct buffer *input, struct buffer *output, ...) The buffer API will be used by further commits.

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.

The first version of the cbmem utility was written in python, but it had issues with 64bit systems and other little hick ups. Since the C version has much fewer dependencies (no python needed on target system), and it works in all corner cases, drop the python version.

2013-01-04cbmem utility: Use mmap instead of fseek/freadStefan Reinauer
The kernel on Ubuntu 12.04LTS does not allow to use fseek/fread to read the coreboot table at the end of memory but will instead abort cbmem with a "Bad Address" error. Whether that is a security feature (some variation of CONFIG_STRICT_DEVMEM) or a kernel bug is not yet clear, however using mmap works nicely.

2013-01-04update CFLAGS for armv7David Hendricks
This updates $CFLAGS used for armv7. Most of them were just added to be consistent with what u-boot does. The important ones here are -march=armv7-a and -mthumb (to allow 16-bit Thumb instructions). 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.
