When using omap_hsmmc without the device model then the allocation of mmc->priv ends up uninitialised.
Signed-off-by: Alex Kiernan alex.kiernan@gmail.com --- I've a board (AM335xx based) which boots fine with 2018-01, with 2018-03-rc1 (actually 1811a92) it fails in the MLO:
U-Boot SPL 2018.03-rc1-00222-g128a503-dirty (Feb 09 2018 - 11:51:50 +0000) Trying to boot from MMC2 omap_hsmmc_send_cmd : DMA timeout: No status update mmc_init: -110, time 1026 spl: mmc init failed with error: -110 SPL: failed to boot from all boot devices ### ERROR ### Please RESET the board ###
Bisecting it out, it's this commit:
