From 36116650440406f99cc2c309f8f7c8388da46241 Mon Sep 17 00:00:00 2001 From: Wolfgang Denk Date: Wed, 11 Aug 2010 09:38:31 +0200 Subject: [PATCH] Cleanup use of CONFIG_SYS_SRAM_BASE and CONFIG_SYS_SRAM_SIZE Traditionally many boards used local definitions for SRAM base address and size (like SRAM_BASE, SRAM_LEN and/or SRAM_SIZE), while the (now) "official" names are CONFIG_SYS_SRAM_BASE and CONFIG_SYS_SRAM_SIZE. The corresponding code in arch/powerpc/lib/board.c was board specific, and has never actually been maintained well. Replace this by feature- specific code and adapt the boards that actually use this. NOTE: there is still a ton of boards using the old #defines, which therefor contain incorrect values in bi_sramstart and bi_sramsize. All respective board maintainers are requested to clean up their respective configurations. Thanks.
