From: Simon Glass Date: Sun, 26 Apr 2020 15:12:57 +0000 (-0600) Subject: board: Add a gd flag for chain loading X-Git-Url: http://git.dujemihanovic.xyz/html/%7B%7B%20.Permalink%20%7D%7D?a=commitdiff_plain;h=ba974a0137edc86cff9727a83cf6be154ab18ef0;p=u-boot.git board: Add a gd flag for chain loading When U-Boot is run from another boot loader, much of the low-level init needs to be skipped. Add a flag for this and adjust ll_boot_init() to use it.
