From: Steve Rae Date: Tue, 7 Jun 2016 18:19:37 +0000 (-0700) Subject: fastboot: sparse: resync common/image-sparse.c (part 2) X-Git-Tag: v2016.07-rc3~20 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=9bc34799c8e6d8907b18e02c405576aa6bf9ce15;p=u-boot fastboot: sparse: resync common/image-sparse.c (part 2) - update fastboot_okay() and fastboot_fail() This file originally came from upstream code.
