[U-Boot] [PATCH v3 00/20] Reorganize directory structure

[Peter Tyser]

This series reorganizes U-Boot's directory structure so that it looks
like:
/arch/$ARCH/
        /lib/<sources currently in lib_$ARCH/>
        /include/asm/<headers currently in incluce/asm-$ARCH/>
        /cpu/<appropriate cpu directories in cpu/ or just files in cpu/$CPU if 1 CPU type>
        /config.mk (old lib_$ARCH/config.mk)

/lib/
        /<source files currently in lib_generic>
        /libfdt/
        /lzma/
        /lzo/

Patches 8 through 19 can be squashed if desired, I split them up to keep
the series somewhat manageable.  Some of the patches still exceed the
mailinglist's arbitrary size limit.  I can post the series on a website
if needed.

I compile tested on PPC, mips, and blackfin and no new errors were
introduced.

Changes since v1:
- Convert to using directory-specific CFLAGS
- No cpu subdirectories for 1-CPU architectures (eg blackfin, mips, etc)
  as mentioned by Mike Frysinger
- Fix libfdt path typo pointed out by Luigi Mantellini
- Added final README fixup patch

Changes since v2:
- Rebased on current TOT
