Subject: board: ti: am57xx: Add support for detection of X15 revb1
X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=f7f9f6be95bc1f484ec118714defd3d6f6f10d4a;p=u-boot.git

board: ti: am57xx: Add support for detection of X15 revb1

BeagleBoard-X15 Rev B1 with SR1.1 platform have incompatible changes for HDMI
GPIO requiring new dtb support. This implies we have to properly identify
the platform now as well. Hence provide a different board name for the
Rev B1 variants.
