Subject: board: ti: am65x: Overwrite get_overlay_mmc
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8633643769b5d5b30567b89a1c0fb00b8f2ac7b2;p=thirdparty%2Fu-boot.git

board: ti: am65x: Overwrite get_overlay_mmc

Unlike other K3 SoC's, am65 SoC has the capability to detect daughter
cards and automatically generate a list of white-space separated overlays
in name_overlays environment variable.

When applied during boot with get_overlay_mmc, the path to overlays with
default distribution is incorrect where path is currently: boot/dtb and
the overlays exist in boot/dtb/ti.

Fix the path in get_overlay_mmc so that overlays are automatically applied
correctly during boot time.
