From 5c651e86ca6d88ae8016578f01fb4daf6d8d4fbc Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sun, 21 Apr 2013 05:52:23 +0000 Subject: [PATCH] nand: Add SPL_NAND support to mxc_nand_spl MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Add support for generic NAND SPL via the SPL framework into the mxc_nand_spl driver. This is basically just a simple rename and publication of the already implemented functions. To avoid the bare-bones functions getting in the way of the NAND_SPL, build them only if CONFIG_SPL_FRAMEWORK is not defined. Also make sure the requested payload is aligned to full pages, otherwise this simple driver fails to load the last page.
