The HXT StarDragon 4800 REP2 (Reference Evaluation Platform) is
an aarch64 ARMv8 server platform with an ast2520 BMC.

Looks good. I will apply it to the Aspeed tree in a few days, after
giving others a chance to review.

Out of interest, are you planning on running OpenBMC on this platform?

Hi Joel,

Thanks for your work.

Yes, I will running OpenBMC on this platform.
And In fact, the OpenBMC basic startup is already running on REP2.
I'm also trying to push the OpenBMC patch for this platform.

Cheers,

Joel
