Subject: arm: imx: imx8m: Only use ROM pointers if not PSCI provider
X-Git-Tag: v2025.01-rc5-pxa1908~1126^2~21
X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=45dd377e3666a38b43143041c76b840c8c16db60;p=u-boot.git

arm: imx: imx8m: Only use ROM pointers if not PSCI provider

The ROM pointers are in fact populated by the ATF BL31 blob, in case
U-Boot itself if the PSCI provider, there is no ATF BL31 blob, hence
ignore the ROM pointers.
