[U-Boot] [PATCH 0/9] AE350 SMP support RISC-V

[Andes]

From: Rick Chen <rick at andestech.com>

This patch series was based on Lukas's patchsets of SMP support for RISC-V.
Add Andestech's PLIC for IPI handling and PLMT to replace Soc timer.
It has been verified on AE350 SMP platform in M-mode and boot SMP kernel ok.

Verification in S-mode is still on-going.
