Subject: [PATCH 13/20] riscv: add Siflower RISC-V SoC family Kconfig support
|
|
|
|
Siflower RISC-V SoCs, including SF21A6826, SF21H8898 and some other
|
|
upcomping chips, are RISC-V chips with T-Head C908 cores for home
|
|
routers and gateways. Add a Kconfig entry named ARCH_SIFLOWER for
|
|
them.
|
|
Notably these chips uses ARM PL011 for UART. ARM_AMBA is selected
|
|
for its driver.
