Stefan Reinauer 2dd161f556 cbfstool: Clean up code
cbfstool has diverged between coreboot upstream and the chromium tree.
Bring in some of the chromium changes, in particular the useful remainders
of cbf37fe (https://chromium-review.googlesource.com/176710)

- fix coding style
- mark unused variables explicitly unused
- remove some dead code

Aaron Durbin 4fde5a66b4 util: add rmodtool for parsing ELF files to rmodules
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.

Alexandru Gagniuc b63b75b0f7 cbfstool: Fix LzmaEnc.c and build with -Wshadow
LzmaEnc.c was full of shadow definitions. Luckily, shadow definitions
were not used after the scope in which they were redefined, so it is
possible to just remove them.

Ronald G. Minnich a8a133ded3 Add section header parsing and use it in the mk-payload step
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

Ronald G. Minnich aa2f739ae8 cbfs: fix issues with word size and endianness.
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.

Hung-Te Lin eab2c81949 cbfstool: Add cbfs_image new CBFS image manipulation API.
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.
