X-Git-Tag: v6.18-rc1~147^2~17^2~50
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=f927049553dfaa27acc099b21095ee488b199687;p=thirdparty%2Fkernel%2Flinux.git

arm64: dts: ti: k3-am62a: Enable remote processors at board level

Remote Processors defined in top-level AM62A SoC dtsi files are
incomplete without the memory carveouts and mailbox assignments which
are only known at board integration level.

Therefore, disable the remote processors at SoC level and enable them at
board level where above information is available.
