If you took the assumption that in "BOOT_DEVICE_MMC1 = Boot from SDHC1 port" in 54e4fcfa3c749a78 ("ARM: mx6: add MMC2 boot device detection support in SPL") I suggest we need to revert it.
Indeed it was my assumption. I agree it should be reverted then.
Thanks for confirming.
Stefano, would you like to take Breno's original patch with the revert?
I think it is ok to take Breno's original patch. It was just a misunderstanding and how boot device order is set was cleared in this thread.
Best regards, Stefano Babic
Or would you like me to resend it with an improved commit log explaining the reason for the breakage?
So to support booting from two SD/MMC devices one should create board_boot_order() function? That way BOOT_CFG2[3:4] can be read there to figure out which MMC1 or MMC2 should be configured as the first boot device.
If you want to determine the SD/MMC port dynamically it seems like a solution.
Or if you always know the SD/MMC port you will boot from then you can simply register the associated SDHC port first.
