2014-08-07cbfstool: process cbfs_payload_segment(s) in host byte orderAaron Durbin
The printing routines of the cbfs_payload_segment assumed the type could be accessed in host order. Each of the fields need to be converted to the host order before inspecting the fields. In addition, this removes all the ntoh*() calls while processing the cbfs_payload_segment structures. cbfstool would crash adding entries or just printing entries containing a payload when -v was passed on the command line.

cbfstool fails to built under 32-bit platforms since commit aa2f739a cbfs: fix issues with word size and endianness. due to the use of '%ld' format specifier on size_t, which on these platforms is only 32-bit.

2014-03-20util: add rmodtool for parsing ELF files to rmodulesAaron Durbin
The current implementation of creating rmodules relies on invoking the linker in a certain manner with the relocations overlaid on the BSS section. It's not really surprising that the linker doesn't always behave the way one wants depending on the linker used and the architecture. Instead, introduce rmodtool which takes an ELF file as an input, parses it, and creates a new ELF file in the format the rmodule loader expects.

There isn't smart merging of the sections into a single PT_LOAD segment.

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.

2014-01-29cbfstool/lzma: Avoid use of typedef with structs and enumsAlexandru Gagniuc
When typedef is used with structs, enums, and to create new typenames, readability suffers. As such, restrict use of typedefs only to creating new data types. The 80 character limit is intentionally ignored in this patch in order to make reviewing easier.

2014-01-29cbfs: fix issues with word size and endianness.Ronald G. Minnich
Add XDR functions and use them to convert the ELF headers to native headers, using the Elf64 structs to ensure we accomodate all word sizes. Also, use these XDR functions for output. This may seem overly complex but it turned out to be much the easiest way to do this. Note that the basic elf parsing function in cbfs-mkstage.c now works over all ELF files, for all architectures, endian, and word size combinations. At the same time, the basic elf parsing in cbfs-mkstage.c is a loop that has no architecture-specific conditionals. Add -g to the LDFLAGS while we're here. It's on the CFLAGS so there is no harm done. This code has been tested on all chromebooks that use coreboot to date. I added most of the extra checks from ChromeOS and they triggered a lot of warnings, hence the other changes. I had to take -Wshadow back out due to the many errors it triggers in LZMA. BUG=None TEST=Build and boot for Peppy; works fine. Build and boot for nyan, works fine. Build for qemu targets and armv8 targets.

2014-01-24cbfstool: correct size left calculation for "empty" entriesAaron Durbin
After removing a file sandwiched between two other files, that file could no longer be re-added at the same location. cbfstool tried to add the file, and a new "empty" entry, which, together, would no longer fit, so it continued checking for the next available space. Change the behavior to add the file if there is enough space for the file alone, then only add the "empty" entry if there is enough space for it.
