[U-Boot] Flashing images bigger than ram

[Ben Goska]

Is there a standard way to have U-Boot flash really large images? I
want to setup rootfs flashing from U-Boot but this requires flashing
an image that is bigger than the ram of my system. I thought about
breaking the image into chunks, but when flashing to NAND with bad
blocks it is difficult to handle skipping the bad blocks.

I know I could make this happen with a custom command added to U-Boot
but I was wondering if someone else had solved the problem already.

My hardware: OMAP3530, 128MB Ram, 256MB NAND.
Trying to flash from MMC (fat, or ext2) to NAND.

Thanks for any help.
