From 76d354f411696d6e19fd3156d18cb0359887ce8a Mon Sep 17 00:00:00 2001 From: Mingkai Hu Date: Fri, 12 Apr 2013 15:56:28 +0800 Subject: [PATCH] powerpc/mpc85xx: explicit cast the SDRAM size to type phys_size_t To avoid sign extension problem, use explicit casting to cast the SDRAM size to type phys_size_t, or else, if the SDRAM size is 2G(0x80000000), it will be extended to 0xffffffff80000000 when phys_size_t is type 'unsigned long long'.
