Subject: MCF532x: make icache_enable use CONFIG_SYS_SDRAM_SIZE
X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=992d7129500d239d684c15fa2d61e0a8f2e64457;p=u-boot.git

MCF532x: make icache_enable use CONFIG_SYS_SDRAM_SIZE

in cpu/mcf532x/start.S, the function icache_enable enables the cache for
a fixed 32MB region starting at the SDRAM start address; this patch
changes the function to cover the region defined by CONFIG_SYS_SDRAM_SIZE
