u-boot.git/common/spl, branch v2017.05 Unnamed repository; edit this file 'description' to name the repository. spl: net: Add FIT image support over network boot 2017-04-09T01:35:08+00:00 Andrew F.

As the load address is no longer hard-coded to the final execution address, legacy image loading will require load_addr to be set correctly in the image header. Signed-off-by: Andrew F.
