X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=1e93cc8473e4fe018aececc8ed3bf8fc2b3ff561;p=u-boot.git

ti_armv7_common: env: Add support for loading FIT images

FIT is a new image format which is a Tree like structure and gives more
flexibility in handling of various images. Mainly used for unification of
multiple images in a single blob and provide security information for each
image.

U-Boot already has support for loading such images, so adding the environment
support to load FIT image on all TI platforms.
