[U-Boot] Regarding NAND flash support in IMX31 and bootm in ubootv2

[R Arun Kumar]

Hai,


I have populated ST 64MB chip and found that the nand flash commands work
for ST 64MB chip.But the same NAND flash drivers does not work for SAMSUNG
flash , Any Help?

Also one more issue is that the linux kernel boot is not seen after the
"booting the kernel." , even though the kernel image works fine in old
u-boot version 2009-08

Any help Please?

Arun
