Subject: pci: Drop DM_PCI check from fdtdec
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=b717f2f2d18e630f276cce524d4d22152ada501b;p=u-boot.git

pci: Drop DM_PCI check from fdtdec

We don't need this check anymore since when PCI is enabled, driver model
is always used.

Sadly this doesn't work with nds32 for some reason to do with the
toolchain. Add a work-around for that.
