From: Simon Glass Date: Sat, 18 Nov 2023 21:04:50 +0000 (-0700) Subject: README: Correct docs for CONFIG_SPL_BUILD X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=1d38722e012c4ca496d5069b95a60bd3392ccf9e;p=u-boot.git README: Correct docs for CONFIG_SPL_BUILD This option is defined in both SPL and TPL builds, so correct the docs related to this. Also point to spl_phase() which is normally a better option. Mention VPL as well.
