From 01624f40eeec33c546150a240f194f057f6dd36e Mon Sep 17 00:00:00 2001 From: Carl-Daniel Hailfinger Date: Tue, 12 May 2009 15:38:55 +0000 Subject: Use helper functions chip_{read,write}[bwl] to access flash chips The semantic patch I used in r418 to make the original conversion to accessor functions was missing one isomorphism: a[b] <=> *(a+b) The semantic patcher Coccinelle was used to create this patch. Semantic patch follows: @@ typedef uint8_t; expression a; volatile uint8_t *b; @@ - b[a] + *(b + a) @@ expression a; volatile uint8_t *b; @@ - *(b) = (a); + chip_writeb(a, b); @@ volatile uint8_t *b; @@ - *(b) + chip_readb(b) @@ type T; T b; @@ ( chip_readb | chip_writeb ) (..., - (T) - (b) + b ) Corresponding to flashrom svn r498.
