Pull MMC updates from Ulf Hansson: ...
is fingered by git bisect as the cause for a mashup of mmc block devices on a Beaglebone Black:
[ 2.916209] mmc1: new high speed MMC card at address 0001 [ 2.923755] mmcblk0: mmc1:0001 MMC04G 3.60 GiB [ 2.929479] mmcblk0boot0: mmc1:0001 MMC04G partition 1 2.00 MiB [ 2.936821] tps65217 0-0024: TPS65217 ID 0xe version 1.2 [ 2.942270] mmcblk0boot1: mmc1:0001 MMC04G partition 2 2.00 MiB [ 2.949388] mmcblk0: p1 p2 [ 2.950031] mmc0: new high speed SDHC card at address e624 [ 2.961118] mmcblk1: mmc0:e624 SU08G 7.40 GiB [ 2.967047] at24 0-0050: 32768 byte 24c256 EEPROM, writable, 1 bytes/write [ 2.974190] mmcblk1: p1 p2
Note how mmc1 => mmcblk0 and mmc0 => mmcblk1.
This produces a failure to boot as the wrong partition is mounted as root (/dev/mmcblk0p2 is now on the wrong mmc).
The bisect tried all the mmc tree patches which were all good. I double-checked by cloning the mmc tree and building both mmc-v4.6 and v4.5-rc6, and both tested good.
I interpret that to mean some change in mmc + some new behavior elsewhere for v4.6 is causing this. Any ideas?
