Hi Aneesh,

I recently started to work on a similar topic: omap3 (devkit8000) nand_spl
support. So I'am really interested in your OMAP4/common work here ;)

In this patch comment you say its common for OMAP3/4 but in
preloader_console_init() is a call to omap4_rev_string()):
> printf("Texas Instruments %s\n", omap4_rev_string());

Regards
Simon
