The default U-Boot environment expects the use of eMMC user partition. To ensure we are using the proper eMMC partition for boot we need to run the `mmc partconf` command.
This patch updates the README instructions to avoid users to follow misleading instructions.

- fix typo
No, please re-read my last response. I think you misunderstood.
If I follow the steps indicated in this patch the eMMC flashing does not work.
I tried it and U-Boot did not update.
Here is the correct procedure that works for me:
=> dfu 0 mmc 0 Flash SPL => dfu 0 mmc 0 Flash U-Boot proper => mmc partconf 0 0 0 0 => saveenv
So you need to fix the README in two points:
1. The command "=> dfu 0 mmc 0" must be issued twice: one for the SPL and one for u-boot-dtb.img - This error was there prior to your change
2. The '=> mmc partconf 0 0 0 0' command needs to be issued after the last dfu command, not before like you did in this patch.
