There must be precisely one device connected on the eSDHC bus. In particular, multiple MMC
devices sharing the one bus are not supported.

Redundancy to support SD/MMC bad blocks, by searching for the BOOT signature in up to 24
blocks, and trying the next block if the BOOT signature is not found, or if a read CRC error is
found.

BOOT signature. This location should contain the value 0x424f_4f54, which is the ascii code for
BOOT. The boot loader code will search for this signature. If the value in this location doesn't match
the BOOT signature, it means that the SD/MMC card doesn't contain a valid user code. In such case
the boot loader code will disable the eSDHC and will issue a hardware reset request of the SoC by
setting RSTCR[HRESET_REQ].
