Subject: [PATCH v2 0/3] RISC-V interrupt controller select cleanup

From: Conor Dooley <conor.dooley@...rochip.com>

Hey Marc, Anup, Palmer,

Submitted a patch yesterday defaulting the SiFive PLIC driver to
enabled [0], and in the ensuing conversation Marc suggested just doing a
select at the arch level and dropping the user selectability completely.

Since we're already selecting SIFIVE_PLIC in Kconfig.socs for all of the
supported SoCs & selecting RISCV_INTC in the arch Kconfig itself,
patches 1 & 2 can go via the irqchip tree without any impact.

@Anup, by the same logic - I think we can also enable the AIA stuff via
selects at the arch level? Dumping as much from Kconfig.socs as possible
is the plan, so adding them there for SOC_VIRT kinda goes contrary to
that.

I spoke with Palmer today about putting my various bits of Kconfig.socs
cleanup on a branch, so I'll take patch 3. It's only in this series as
it is related work, rather due to any sort of dependency between the
patches.

Thanks,
Conor.

Conor Dooley (3):
  irqchip/sifive-plic: remove user selectability of SIFIVE_PLIC
  irqchip/riscv-intc: remove user selectability of RISCV_INTC
  RISC-V: stop selecting SIFIVE_PLIC at the SoC level
