The LZMA compression algorithm, currently the only one available, will fail
if you ask it to write more data to the output than you've given it space for.
The code that calls into LZMA allocates an output buffer the same size as the
input, so if compression increases the size of the output the call will fail.
The caller(s) were written to assume that the call succeeded and check the
returned length to see if the size would have increased, but that will never
happen with LZMA.
Rather than try to rework the LZMA library to dynamically resize the output
buffer or try to guess what the maximal size the data could expand to is, this
change makes the caller simply print a warning and disable compression if the
call failed for some reason.
This may lead to images that are larger than necessary if compression fails
for some other reason and the user doesn't notice, but since compression
errors were ignored entirely until very recently that will hopefully not be
a problem in practice, and we should be guaranteed to at least produce a
correct image.

When compression fails for whatever reason, the caller should know about it
rather than blindly assuming it worked correctly. That can prevent half
compressed data from ending up in the image.
This is currently happening for a segment of depthcharge which is triggering
a failure in LZMA. The size of the "compressed" data is never set and is
recorded as zero, and that segment effectively isn't loaded during boot.

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.

Now that unused functions have been removed, the global "arch" is only

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.

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.

isolated just like mkpayload and mkstage.
Since the add-flat-binary command creates a payload in the end , move payload
processing to cbfs-mkpayload.c.

cbfstool coreboot.rom add-flat-binary -f u-boot.bin -n fallback/payload \
-l 0x100000 -e 0x100020

Add -v (verbose) to every command, and allow printing debug messages.
Revise logging and debugging functions (fprintf(stderr,...), dprintf...)
and verbose message printing with following macros:
ERROR(xxx): E: xxx
WARN(xxx) W: xxx
LOG(xxx) xxx
INFO(...) INFO: xxx (only when runs with -v )
DEBUG(...) DEBUG: xxx (only when runs with more than one -v)
Example:
cbfstool coreboot.rom print -v
cbfstool coreboot.rom add -f file -n file -t raw -v -v
Normal output (especially for parsing) should use printf, not any of these
macros (see usage() and cbfs_locate(), cbfs_print_directory() for example).
