From: AKASHI Takahiro Date: Thu, 29 Oct 2020 04:47:43 +0000 (+0900) Subject: common: update: add a generic interface for FIT image X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=3149e524fc1e76ec1420cd17588c724d4232a904;p=u-boot.git common: update: add a generic interface for FIT image The main purpose of this patch is to separate a generic interface for updating firmware using DFU drivers from "auto-update" via tftp. This function will also be used in implementing UEFI capsule update in a later commit.
