tools: imximage: Load a size that is multiple of 512
In order to mx53 ROM to properly load the U-boot image, its header size should be multiple of 512 bytes. This issue was observed with gcc 4.6.2/4.7.3, which caused data aborts: U-Boot 2013.01-rc2-00172-gf8cfcf1-dirty (Dec 26 2012 - 13:13:28) Board: MX53 LOCO I2C: ready DRAM: 1 GiB MMC: FSL_SDHC: 0, FSL_SDHC: 1 In: serial Out: serial Err: serial CPU: Freescale i.MX53 family rev2.1 at 1000 MHz Reset cause: WDOG Net: FEC Warning: FEC using MAC address from net device Hit any key to stop autoboot: 0 data abort MAYBE you should read doc/README.arm-unaligned-accesses pc : [<aff72220>] lr : [<aff721fc>] sp : af565e20 ip : af566918 fp : 00000000 r10: 00000003 r9 : affabb5b r8 : af565f58 r7 : 00000000 r6 : 36747fff r5 : af5668e8 r4 : 36747fff r3 : af5668ec r2 : af5668eb r1 : 00000000 r0 : af5668e8 Flags: NzcV IRQs off FIQs off Mode SVC_32 Resetting CPU ... resetting ... ,and this patch fixes it. Also, even though the ROUND macro is already defined in common.h, the reason for redefining it in image.h is explained by Stefano Babic: "I will remark a previous comment - even if including common.h seems a good idea to avoid duplications, it makes tools like mkimage to depend on the selected board, because <board>_config must run. Even if this is not a problem for us u-boot developers, it becomes an issue when these tools are included in distros (like u-boot-tools in Ubuntu) and cannot be packaged."
