From e889dfca12ce95cdeaa50f66d1f33ad8fed4ca58 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Fri, 2 Jun 2017 12:29:54 -0700 Subject: MIPS: generic: Abstract FDT fixup application Introduce an apply_mips_fdt_fixups() function which can apply fixups to an FDT based upon an array of fixup descriptions. This abstracts that functionality such that legacy board code can apply FDT fixups without requiring lots of duplication.
