From 77cd89e75563742aa32cf3d216ac9ff649d1d70e Mon Sep 17 00:00:00 2001 From: pekon gupta Date: Fri, 18 Jul 2014 17:59:40 +0530 Subject: ARM: omap: fix GPMC address-map size for NAND and NOR devices Fixes commit a0a37183bd75e74608bc78c8d0e2a34454f95a91 ARM: omap: merge GPMC initialization code for all platform 1) NAND device are not directly memory-mapped to CPU address-space, they are indirectly accessed via following GPMC registers: - GPMC_NAND_COMMAND_x - GPMC_NAND_ADDRESS_x - GPMC_NAND_DATA_x Therefore from CPU's point of view, NAND address-map can be limited to just above register addresses. But GPMC chip-select address-map can be configured in granularity of 16MB only. So this patch uses GPMC_SIZE_16M for all NAND devices. 2) NOR device are directly memory-mapped to CPU address-space, so its address-map size depends on actual addressable region in NOR FLASH device. So this patch uses CONFIG_SYS_FLASH_SIZE to derive GPMC chip-select address-map size configuration.
