Subject: bootstd: sata: bootdev scanning for ahci sata with no drive attached
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=1052920aa987061f4d2aaa768dfe0ba15b6f10f7;p=u-boot.git

bootstd: sata: bootdev scanning for ahci sata with no drive attached

It's normal to have no SATA drive attached to the controller, so return a
successful status when there is no block device found after probing.

Note: this patch depends on the previous patch
https://patchwork.ozlabs.org/project/uboot/patch/20230917230649.30357-1-mibodhi@gmail.com/

Resend the right patch.
