Subject: [PATCH v2 1/2] RISC-V: enable HW_HAS_PCI
Date: Mon, 22 Nov 2021 22:34:35 +0100	[thread overview]
Message-ID: <20211122213436.309749-1-ahmad@a3f.at> (raw)

With the recently added generic ECAM PCI driver, we can now use PCI
device drivers on the RISC-V Virt machine. Enable HW_HAS_PCI, so the
driver and bus support can be selected. As HW_HAS_PCI on its own doesn't
add any code, just enable it for the whole architecture.

Signed-off-by: Ahmad Fatoum <ahmad@a3f.at>

v1 -> v2:
  - add missing <asm/pci.h>
  - select CONFIG_HW_HAS_PCI from CONFIG_RISCV, instead of CONFIG_SOC_VIRT
