This patch add the MX53 boot image support.

This patch has been tested on Freescale MX53EVK board and MX51EVK board.

Signed-off-by: Jason Liu r64343@freescale.com

--- Changes for v2: - Address the following comments from Stefano, - Get rid of #ifdef in the imximage.h and .c file and use the runtime check for imximage version - Document the IMXIMAGE_VERSION definiton in doc/README.imximage - Move mx53evk/config.mk and mx53evk/imximage.cfg to MX53EVK board support patch.

Changes for v3: - Address the following comments from Stefano, - Not change the mx51evk file. The code should take VERSION=1 as default, and we do not need to change the actual boards. - add a note in the documentation and raise an error in code if the VERSION command is read after any other suitable commands. - Change command IMXIMAGE_VERSION simply to IMAGE_VERSION - Need recognize the version directly from its structure and not storing the version into the header when do header verify and print. - Use function pointer to simpliy the code when the version of header is recognized Changes for v4: - Address the following comments from Wolfgang, - Keep the imximage_cmds table sorted, - Add braces for (expx) && (expy) gloably, - Return failure to upper call if met errors for function - Add comments for function set_dcd_rst_v1 alike, - Re-orgnize code to avoid deep nesting, --- doc/README.imximage | 12 +- tools/imximage.c | 527 +++++++++++++++++++++++++++++++++++++-------------- tools/imximage.h | 110 +++++++++-- 3 files changed, 489 insertions(+), 160 deletions(-)
