This adds support to update firmware on qspi flash present on am437x-sk-evm and am43xx-epos-evm via DFU.

On device: => setenv dfu_alt_info ${dfu_alt_info_qspi} => dfu 0 sf 0:0

On host: $ sudo dfu-util -l $ sudo dfu-util -D u-boot.img -a u-boot.img

Tested on am437x-sk-evm by flashing u-boot.img and zImage.

It's always xip in am43xx, we copy u-boot.bin instead of u-boot.img. Just rename this to u-boot.bin. Rest looks good to me.

Thanks and regards, Lokesh
