Got overo board revisions 0 & 1 booting fine from SDcard ( revision 2 might need 
further alignment.. ) [1]. 

To prevent modifying multiple locations I left 

CONFIG_SYS_TEXT_BASE           0x80080000

To test NAND I did on u-boot console ( based on [2] )

| nand erase.chip
| mmc rescan 0

| # write MLO
| fatload mmc 0 $loadaddr MLO
| nandecc hw
| nand write $loadaddr 0 ${filesize}

| # write u-boot
| fatload mmc 0 ${loadaddr} u-boot.bin
| nand write ${loadaddr} 80000 ${filesize}

| # write the kernel
| fatload mmc 0 ${loadaddr} uImage
| nand write ${loadaddr} 280000 ${filesize}

After power off / power on without SDcard I get

| Boot SPL 2011.09-01172-gfdbe8b9-dirty (Dec 13 2011 - 00:58:36)
| Texas Instruments Revision detection unimplemented
Is it correct that this is only implemented for OMAP4/5 so for OMAP3 this 
message is OK?
| mkimage signature not found - ih_magic = ea000014
| Assuming u-boot.bin ..

Asking google for 'mkimage signature not found' showed me many pastebins but no 
answer. Anybody out there with a hint?
