From ca5def3f30860a97cc76453eb846fffbde997035 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Tue, 31 Aug 2010 10:00:10 +0200 Subject: cfi_flash: Simplify dynamic flash bank number detection This patch simplifies the use of CONFIG_SYS_MAX_FLASH_BANKS_DETECT. By moving these optional variables and defines into the common code, board specific code is minimized. Currently only the following board use this feature: APC405, IDS8247, TQM834x And IDS8247 doesn't seem to really need this feature, since its not updating the bank number variable at all. So this patch removes the definition of CONFIG_SYS_MAX_FLASH_BANKS_DETECT from this board port. This new framework will be used by the upcoming lwmon5 update as well.
