Richard Spiegel b93796d624 payloads/coreinfo/cbfs_module.c: Get rid of void pointer math
Pointer math with void pointers is illegal in many compilers, though it
works with GCC because it assumes size of void to be 1. Change the pointers
or add parenthesis to force a proper order that will not cause compile
errors if compiled with a different compiler, and more importantly, don't
have unsuspected side effects.

BUG=b:118484178
TEST=Build coreinfo with original code, run objdump and saved output. Added
modifications, build coreinfo again, run objdump again, compared objdump
outputs.

README

This is a silly little program that demonstrates how cool libpayload is
and also serves a purpose.  It is fun and educational!

Requirements
------------

You should use the coreboot reference cross compiler. If you insist on using
your system compiler, some Linux distributions might require you to install
a package called gcc-multilib if you are on a 64bit system.

Build
-----

You need libpayload to build coreinfo. So, first, you need follow the README of
libpayload to build it but install libpayload into its own directory by doing
this:

 $ make DESTDIR=/path/to/libpayload/install install

Then you can build coreinfo now:

 $ cd coreinfo

 $ make menuconfig
 
 $ make
