This series fixes a some warnings, adds support for reading
NAND parameter page (this allows to identify POP parts from
the same manufacturer), and finally adds support for pandora
board, see http://www.openpandora.org/ .

This can also be pulled from:
git://git.openpandora.org/pandora-x-loader.git for_upstream

Grazvydas Ignotas (6):
Drop I2C dependency on MMC
Do i2c init before serial init
Add some missing function prototypes
k9f1g08r0a: fix various warnings
k9f1g08r0a: add support for reading parameter page
Add support for pandora board

I could not find evidence this is needed, and all boards build fine
without it.

pandora needs this to power the level shifter so that
serial output can be seen.

this allows to read full NAND model name, which is useful to
distinguish between POP parts that both have the same manufacturer/device
id, but different RAM.
