With the previous ELF stage extract support the resulting
ELF files wouldn't handle rmodules correctly in that the
rmodule header as well as the relocations were a part of
the program proper. Instead, try an initial pass at
converting the stage as if it was an rmodule first. If it
doesn't work fall back on the normal ELF extraction.

Instead of reaching into src/include and re-writing code
allow for cleaner code sharing within coreboot and its

for the utilities to provide a printk() declaration within
a <console/console.h> file. That way code which uses printk()
can than be mapped properly to verbosity of utility parameters.

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.

Aaron Durbin 785e47bbf3 rmodtool: add support for ARM
Add support for creating ARM rmodules. There are 3 expected
relocations for an ARM rmodule:
- R_ARM_ABS32
- R_ARM_THM_PC22
- R_ARM_THM_JUMP24

R_ARM_ABS32 is the only type that needs to emitted for relocation
as the other 2 are relative relocations.

BUG=chrome-os-partner:27094
BRANCH=None
TEST=Built vbootstub for ARM device.

Aaron Durbin 518a322d58 rmodtool: correct final memory size calculation
Apparently when I originally wrote this I confused myself to no end.
The code/data of an rmodule has a set memory size which is associated
with the .payload section. The relocation entries may increase the
overall footprint of the memory size if the rmodule has no bss but
a lot of relocations. Therefore, just compare relocation entries size
plus the file size of the .payload section with the memory size of the
paylod section. The .empty section is added only when we have not met
the final target size.

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.
