From: Tom Rini Date: Sat, 2 Apr 2022 22:18:57 +0000 (-0400) Subject: Revert "global: Remove CONFIG_SYS_EXTRA_OPTIONS support" X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=25b8acee2ea11a9edc100c42a61f5d6187eb6167;p=u-boot.git Revert "global: Remove CONFIG_SYS_EXTRA_OPTIONS support" Unfortunately, we require additional logic to buildman to support this removal and still use SYS_SOC, etc, for build targets. This reverts commit eeec00072d7a0b5b91896d014618e558ce438738.
