Background Info: Some PPC440/460 boards have caches enabled in the Boot/FLASH TLB (via init.S) to speed up the boot process. In relocate_code (start.S) the cache inhibit attribute for this TLB is set to disable cache. This is needed for the CFI FLASH driver. This patch now cleans this code up: - CONFIG_SYS_TLB_FOR_BOOT_FLASH is defined to 0 (default TLB) if not defined in the top of this file. This way, we can remove an ugly #ifdef in this code. - Replace complex "#if defined(CONFIG_440EP) || defined(CONFIG_GR)..." statement with "#if defined(CONFIG_440)". - Remove unnecessary cache invalidate calls resulting in faster bootup.
