[PATCH 152/459] drm/amd/powerplay: smu needs to be initialized after rlc in direct mode

[Alex Deucher]

From: Huang Rui <ray.huang at amd.com>

For gfx 10, rlc firmware loading relies on smu firmware is loaded firstly, so in
direct type, it has to load smc ucode here before rlc. And meanwhile, the smu
initialization has to move after rlc, otherwise, smu message will get failure
during the handshake with rlc and smu.
