Are these changes ported to u-boot yet.
Would this be able to support 4k page size NAND flash. I took the
latest snapshot from the U-boot GIT and trying to boot out of a 4K
NAND on this but haven't been succesful as of now.
I believe we used have a separate mxc_nand_load.S assembly code in
earlier u-boot v2.0 which would load the first 4k from the NAND to the
NFC  SRAM and then the rest of the uboot is loaded after SDRAM /DDR is
initialized. But with the lates code you have in uboot GIT, looks like
all this is done in C after a minimal stack is setup.

Please help me understand this better.
