Subject: arm: dts: fsl-ls1088a: match Linux FDT by disabling PCIe by default
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=843f60b4e8b6bd31e4a2ece3eb028f5e04cae9c9;p=u-boot.git

arm: dts: fsl-ls1088a: match Linux FDT by disabling PCIe by default

The Linux kernel fsl-ls1088a.dtsi disables (status="disabled")
all PCIe controllers by default, with the bootloader (i.e U-Boot)
enabling the appropriate controllers (specified by the board
reset control word/RCW) by FDT fixup.

However, U-Boot needs these controllers to be enabled
to be usable, which we can add in the u-boot only dtsi.
