From 43c9f434922ff834a6589709714f83a78c399bc1 Mon Sep 17 00:00:00 2001 From: Timur Tabi Date: Tue, 23 Sep 2008 09:47:01 -0500 Subject: [PATCH] powerpc: remove support for bootmem-allocated memory for the DIU driver Early versions of the Freescale DIU framebuffer driver depended on a bootmem allocation of memory for the video buffer. The need for this feature was removed in commit 6b51d51a, so now we can remove the platform-specific code that allocated that memory.
