Philipp Deppenwiese 5ada0023d1 cbfstool: Add ifittool
Add the IntelFirmwareInterfaceTable-tool to modify the FIT.
As cbfstool is overloaded with arguments, introduce a new tool
to only modify FIT, which brings it's own command line syntax.

Provide clean interface to:
* Clear FIT
* Add entry to CBFS file
* Add entry to REGION
* Delete entries
* Add support for types other than 1
* Add support to dump current table
* Add support for top-swap
* Sort entries by type

Most code is reused from existing cbfstool and functionality of cbfstool
is kept. It will be removed once the make system uses only ifittool.

Based on "Intel Trusted Execution Technology (Intel TXT) LAB Handout"
and https://github.com/slimbootloader/slimbootloader .

Nico Huber d44221f9c8 Move compiler.h to commonlib
Its spreading copies got out of sync. And as it is not a standard header
but used in commonlib code, it belongs into commonlib. While we are at
it, always include it via GCC's `-include` switch.

Some Windows and BSD quirk handling went into the util copies. We always
guard from redefinitions now to prevent further issues.

Sol Boucher 32532ac92d cbfstool: Make update-fit action work on new-style images
Because new images place the bootblock in a separate region from the
primary CBFS, performing an update-fit operation requires reading an
additional section and choosing a different destination for the write
based on the image type. Since other actions are not affected by these
requirements, the logic for the optional read and all writing is
implemented in the cbfs_update_fit() function itself, rather than
relying on the main() function for writing as the other actions do.

Patrick Georgi b890a1228d Remove address from GPLv2 headers
As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.

However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.

util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

Sol Boucher 0e53931fee cbfstool: Clean up in preparation for adding new files
This enables more warnings on the cbfstool codebase and fixes the
issues that surface as a result. A memory leak that used to occur
when compressing files with lzma is also found and fixed.
Finally, there are several fixes for the Makefile:
 - Its autodependencies used to be broken because the target for
   the .dependencies file was misnamed; this meant that Make
   didn't know how to rebuild the file, and so would silently
   skip the step of updating it before including it.
 - The ability to build to a custom output directory by defining
   the obj variable had bitrotted.
 - The default value of the obj variable was causing implicit
   rules not to apply when specifying a file as a target without
   providing a custom value for obj.
 - Add a distclean target for removing the .dependencies file.

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.

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.

Alexandru Gagniuc f87c20a00d cbfstool: Properly handle EOF in update_fit step
During the update_fit step, 'file_length' is used to determine how many
bytes are left in the CBFS file. It was decremented in a loop from an
array 'mcus[num_mcus].size', but 'num_mcus' was incremented right before.
Since 'mcus' is memset(0) externally, 'file_length' was never decremented.

The loop exited when it reached a dummy terminator, usually 48 bytes of 0
which are internationally added to microcode blobs in coreboot. However,
if that terminator is removed, the loop doesn't stop and continues until
it segfaults.
