add-glmo-mmc.patch

Browse Source 
Moves various .h into include from drivers
Gets glamo-mmc.h working so we can detect
card ID / Size if the card is plugged in.

Adds FAT / MMC kernel source entry for GTA02 that
is first before the NAND one.  When it works it will
favour to boot off SD Card if a kernel is found there, but
right now we don't have a working filesystem parser and
partition handling hooked up.
