[U-Boot] [PATCH] ARM: omap3_logic: Add scripts to program NAND
This patch adds scripts to burn the kernel, U-Boot, and MLO to NAND. The RootFS needs to be added and programmed from the kernel for now.

Do you really need this all in environment? What about making this u-boot script and store it on mmc together with MLO, u-boot.img, etc...

I can see that argument. I only added it because the custom version we have published has similar types of scripts. Because we distribute modules and not final product, I was trying to make it easier for our customers to use U-Boot.
I guess I'm ok with dropping it in favor of a boot script from the SD card.
