From d21a329866a1299b180f8b14b6c73bee3d754e57 Mon Sep 17 00:00:00 2001 From: Julius Werner Date: Thu, 19 Feb 2015 14:08:04 -0800 Subject: arm(64): Replace write32() and friends with writel() This patch is a raw application of the following spatch to the directories src/arch/arm(64)?, src/mainboard/, src/soc/ and src/drivers/gic: @@ expression A, V; @@ - write32(V, A) + writel(V, A) @@ expression A, V; @@ - write16(V, A) + writew(V, A) @@ expression A, V; @@ - write8(V, A) + writeb(V, A) This replaces all uses of write{32,16,8}() with write{l,w,b}() which is currently equivalent and much more common. This is a preparatory step that will allow us to easier flip them all at once to the new write32(a,v) model.
