From: Ryan Harkin Date: Tue, 9 Apr 2013 02:20:30 +0000 (+0000) Subject: ARM: vexpress: refactoring of Versatile Express CA9x4 support X-Git-Tag: v2013.07-rc1~68 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=9b58a3f606e46cb335d44458e53a37d9b221f785;p=oweals%2Fu-boot.git ARM: vexpress: refactoring of Versatile Express CA9x4 support The current ca9x4_ct_vxp platform contains support for a Versatile Express motherboard with a quad core A9 core tile. This patch separates the Versatile Express motherboard code and the A9 specific code, to ease supporting more core tiles in the next patches. Andre: merged the first two of Ryan's original patches and did some checkpatch fixes.
