Joel's on leave and I'm having to manage some personal concerns as well as other professional priorities. I'm trying to find time to address the BMC patch backlog but it really is a best-effort thing at the moment. Andrew

Enabling UART1 for that on the BMC piques my interest :) Apologies for the delay in reviewing. Andrew
Dear Supreeth, Thank you for your patch. Should you resent three more nits.

I’d capitalize I2Cs, UARTs, and MAC, but would write fans. Also, could you please make the summary a statement by adding a verb in imperative mood. Maybe: Add initial device tree for AMD Onyx Platform I’d also add spaces after the colons in the commit message summary. […] Kind regards, Paul
