From fecb5ade3b37f62981f2b05b621005850173aaa9 Mon Sep 17 00:00:00 2001 From: Jason Jin Date: Fri, 19 Sep 2008 17:32:49 +0800 Subject: [PATCH] Fix the NAND size overflow issue. When the total size of all NAND devices exceeds 4 GiB, the size will overflow. This patch tries to fix this. Note that we still have a problem when a single NAND device is bigger than 4 GiB: then the overflow would actually happen earlier, i. e. when storing the size in nand_info[].size, as nand_info[].size is an "u_int32_t".
