* m68k: fix an undefined behavior warning of M5253DEMO boardMasahiro Yamada2014-07-22-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The latest GCC is so clever that it reports more warnings than old ones did: ------------------------------>8------------------------------ board/freescale/m5253demo/flash.c: In function 'flash_get_offsets': board/freescale/m5253demo/flash.c:65:23: warning: iteration 2047u invokes undefined behavior [-Waggressive-loop-optimizations] info->start[k + 1] = info->start[k] + CONFIG_SYS_SST_SECTSZ; ^ board/freescale/m5253demo/flash.c:64:3: note: containing loop for (k = 0, j = 0; j < CONFIG_SYS_SST_SECT; j++, k++) { ^ ------------------------------8<------------------------------ The cause of the warning is like this: The for statement iterates 2048 times in flash_get_offsets() func. (Notice CONFIG_SYS_SST_SECT is defined as 2048) The last iteration does info->start[2048] = info->start[2047] + CONFIG_SYS_SST_SECTSZ; causing an undefined behavior. (Please note the array size of info->start is 2048. CONFIG_SYS_MAX_FLASH_SECT is defined as 2048 for this board.) This commit fixes that so as not to overrun the info->start array.
