X-Git-Tag: v2018.05-rc3~1^2~16
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d9cb9aec743265b56a57e89ec20dde6f38d5e554;p=platform%2Fkernel%2Fu-boot.git

warp7: hab: Set environment variable indicating IVT offset

This patch introduces the environment variable ivt_offset. When we define a
load address for Linux or DTB or any file the IVT associated with that file
is prepended. We extract the actual load addresses from u-boot.cfg and feed
these values into the code-signing process - hence we want u-boot to have
the real load addresses exported in uboot.cfg.

ivt_offset represents the addition or subtraction from the load address
that must happen to find an IVT header.
