Subject: corstone1000: add boot index
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=bc91ca4b8bcb2d6d6ce6b04b7814bbbdf47374fe;p=u-boot.git

corstone1000: add boot index

it is expected that the firmware that runs before
u-boot somehow provide the information of the bank
for now we will fetch the info from the metadata
since the Secure enclave is the one responsible for
this information.
