This adds support for generation of ANSI 3.64 escape sequences to the
PS/2 keyboard driver.
This change significantly refactors the code:
o It adds an FSA to support 0xE0 and 0xE1 multibyte PS/2
scan code sequences.
o It converts the PS/2 scan codes to USB scan code values
to facilitate sharing upper level code in future changes.
Reasons to use USB scan codes:
o Standard
o Simple conversion to ASCII / ANSI 3.64
o Ability to share complex processing / state code
o Shared international keymaps in higher level code
o It adds an ANSI 3.64 escape sequence generator for USB
special keys; the intent of doing this is to allow the
transparent use of PS/2, USB, and network or serial
devices using the same upper level u-boot clients.
o It adds an input FIFO which is an almost verbatim copy
of the Tegra matrix keyboard driver; future changes are
expected to share the FIFOcode among all keyboard drivers.
International keyboard support is expected to be handled at a higher
layer in the future, using a much smaller NRCS (National Replacement
Character Set) table instead of a duplicat table.
Combined, the changes reduce the overall source file size by about
5K, and removes about 4K from the data segment as well.
Note: Use of typedef for FSA states allows compiler to prohibit
switch statement without default case from omitting states.
BUG=chrome-os-partner:6580
TEST=Removed backslash from generated 3.64 sequences, stopped boot at
command line, verified character sequence generation.

add nand flash support to SXNI855T configuration
fix/extend nand flash support:
- fix 'nand erase' command so does not erase bad blocks
- fix 'nand write' command so does not write to bad blocks
- fix nand_probe() so handles no flash detected properly
- add doc/README.nand
- add .jffs2 and .oob options to nand read/write
- add 'nand bad' command to list bad blocks
- add 'clean' option to 'nand erase' to write JFFS2 clean markers
- make NAND read/write faster
