2014-02-02Add section header parsing and use it in the mk-payload stepRonald G. Minnich
This completes the improvements to the ELF file parsing code. We can now parse section headers too, across all 4 combinations of word size and endianness. I had hoped to completely remove the use of htonl until I found it in cbfs_image.c. That's a battle for another day. There's now a handy macro to create magic numbers in host byte order. I'm using it for all the PAYLOAD_SEGMENT_* constants and maybe we can use it for the others too, but this is sensitive code and I'd rather change one thing at a time. To maximize the ease of use for users, elf parsing is accomplished with just one function: int elf_headers(const struct buffer *pinput, Elf64_Ehdr *ehdr, Elf64_Phdr **pphdr, Elf64_Shdr **pshdr) which requires the ehdr and pphdr pointers to be non-NULL, but allows the pshdr to be NULL. If pshdr is NULL, the code will not try to read in section headers. To satisfy our powerful scripts, I had to remove the ^M from an unrelated microcode file. BUG=None TEST=Build a peppy image (known to boot) with old and new versions and verify they are bit-for-bit the same. This was also fully tested across all chromebooks for building and booting and running chromeos. BRANCH=None Change-Id: I54dad887d922428b6175fdb6a9cdfadd8a6bb889 Signed-off-by: Ronald G.

2013-08-31Add a (b)zImage parser to cbfstoolPatrick Georgi
In the great tradition of LinuxBIOS this allows adding a kernel as payload. add-payload is extended to also allow adding an initial ramdisk (-I filename) and a command line (-C console=ttyS0).

2013-02-09cbfstool: Handle alignment in UEFI payloadsPatrick Georgi
Tiano for X64 is much cleaner to start up when using higher alignments in firmware volumes. These are implemented using padding files and sections that cbfstool knew nothing about. Skip these.

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.
