[U-Boot] [PATCH V3 3/3] mkimage: adding support for Davinci AIS image
Stefano Babic
sbabic at denx.de
Mon Oct 17 12:07:43 CEST 2011
Some Davinci processors supports the Application
Image Script (AIS) boot process. The patch adds the generation
of the AIS image inside the mkimage tool to make possible
to generate a bootable U-boot without external tools
(TI Davinci AIS Generator).
Signed-off-by: Stefano Babic <sbabic at denx.de>

Changes since V2:
- rebased on mainline and sort uimage_type list (Wolfgang Denk)
Changes since V1:
- removed warning in gcc 4.6 iwhen -Wunused-but-set-variable is set
- drop remained warnings raised by checkpatch
