Subject: arm: mach-k3: am62: move device identification accessor functions to header
X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=9c68b0427cd75b22758f8b262a6b9e8bcca64320;p=u-boot.git

arm: mach-k3: am62: move device identification accessor functions to header

mach-k3/am625_fdt.c does fdt fixup depending on fields in the device
identification register. Move the accessors to the device identification
register as inline functions into the am62_hardware.h header, so that
they can be used for other functionality.
