Subject: arm64: versal: Fix emmc boot mode boot_target issue
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=7c5b7bb1d7205f6c48419cd72c070386a19ca745;p=u-boot.git

arm64: versal: Fix emmc boot mode boot_target issue

Emmc boot devcie is mounted to sdhci@f1050000 controller on versal, while
in emmc boot mode, boot tragets are set to mmc0. So removed mmc0 and using
the dev seq number from the sdhci@f1050000 controller.
Dev seq number is setup based on DT aliases that's why needs to be setup at
run time.
