ARM_AMBA is selected by ARM64 already, you don't need that one here.

ARM_GIC and ARM_GIC_v3 are also selected by ARM64

ARM64 selects ARM_PSCI_FW (which should select ARM_PSCI, please verify)

ARM64 selects COMMON_CLK already.

You're not going to add one ARCH entry for each MTK Airoha platform, are you?

(if you are, that's wrong)

....so the help text must be refactored; you could say something like
"This enables support for the ARM64 based Airoha SoCs"

...also, I'm undecided whether MTK should be mentioned or not, here, as those
SoCs are (...at least the 7581 seems to be) really based on MediaTek router
chips, in many instances, sharing the same IPs.


Cheers,
