Hi Vladimir,

As the boot order in the kernel continues to change, sometimes it may
happen that the eSDHC controller mmc@2150000 (the one for eMMC) gets
probed before the one at mmc@2140000 (for external SD cards). The
effect
is that the eMMC controller gets the /dev/mmcblk0 name, and the SD card
gets /dev/mmcblk1.
Thanks for taking care.
Since the introduction of this SoC, that has never happened in
practice,
even though it was never guaranteed in theory. Setting
"root=/dev/mmcblk0p2" in /proc/cmdline has always caused the kernel to
use the second partition from the SD card as the rootfs.
Preserve that old behavior by adding some aliases which create naming
consistency:
- the SD card controller uses /dev/mmcblk0
- the eMMC controller uses /dev/mmcblk1
Could you change this behaviour for the sl28 board(s)? I've always
found it counter-intuitive to have mmcblk1 being the eMMC on a board
which always have the eMMC populated. All our images uses UUIDs for
the "root=" parameter and, technically, the order wasn't specified yet.
So I'd like to have the eMMC as /dev/mmcblk0 and the SD card as
/dev/mmcblk1.
