[U-Boot] [PATCH 0/3] omap3: mvblx: small changes
A few minor changes to mvblx
Howard Gray (1): omap3: mvblx: change console to ttyO0 and make silent by default.
Michael Jones (2): omap3: mvblx: select fpgafilename according to orientation omap3: mvblx: pass FPGA version to the kernel

Michael, you should to add a s-o-b from the original author here too. Best placed before yours. So this should be:

This along with the rest of the series have been applied to u-boot-ti/msater, thanks!
Rather than load the FPGA file from the FAT partition, look at entry in system EEPROM to decide which file to retrieve directly from the EXT3 partition.

Extract FPGA version from the .rbf and pass this info to the kernel.
