Can we keep this? Without this, we need to burn u-boot.img into sdcard, but i prefer to load u-boot.img from the fat partition.
Well, how U-Boot is stored on the SD-Card is a decision that you take based on the balance safety against comfortably. Both are ok on my side. If we put u-boot.img in raw SD at a fixed address, it is very uncommon that a user destroy accessing it. On the other side, putting it into a FAT partition makes easier to update for everybody - just copying it into a disk. The issue reported by Fabio is like a corrupted SD-Card - the SD-Card does not contain the correct bootloader and it is ok if it does not boot or hangs. Both ways have advantages and disadvantages.
I am trying to get this more standard across Freescale boards.
Like it was pointed out here: http://lists.denx.de/pipermail/u-boot/2015-August/222061.html
I think it can be confusing for the end user if each FSL board has a different way for booting u-boot.img, so that's why I chose the common approach here.
Most of us agree to unify i.MX boards using storing the bootloader as raw data.
Applied to u-boot-imx, thanks !
