Merge patch series "arm: aspeed: add initial AST2700 SoC support"

Ryan Chen <ryan_chen@aspeedtech.com> says:

AST2700 is the 8th generation of Integrated Remote Management
Processor introduced by ASPEED Technology Inc. It is a Board
Management Controller (BMC) SoC family with a dual-die architecture:
SoC0 ("CPU" die with four ARM Cortex-A35 application cores) and
SoC1 ("IO" die with peripherals) each SoC have its own SCU PLLs,
clock dividers and reset domains.
