[PATCH/RFC] riscv: defconfig: Disable RZ/Five peripheral support
Posted by Geert Uytterhoeven 1 year, 4 months ago 
There is not much point in keeping support for RZ/Five peripherals
enabled, as the RZ/Five platform option (ARCH_R9A07G043) is gated behind
NONPORTABLE.  Hence drop all config options that enable built-in or
modular support for peripherals found on RZ/Five SoCs.

Disable USB_XHCI_RCAR explicitly, as its value defaults to the value of
ARCH_RENESAS, which is still enabled.

Questions:
  1. Perhaps the intention is to keep all RZ/Five peripheral support
     enabled, so RZ/Five users can start from the defconfig, and
     "just"[1] enable NONPORTABLE and ARCH_R9A07G043?

     [1] Nope, need to disable RISCV_ISA_ZICBOM and ERRATA_THEAD_CMO
	 (and whatever else in the future?), too.

  2. Perhaps CONFIG_ARCH_RENESAS=y should be dropped, too?
     In addition to USB_XHCI_RCAR, that would get rid of SOC_BUS,
     PINCTRL_RENESAS, CLK_RENESAS, and SOC_RENESAS.

I think it does make sense if we drop the above configs too as anyway
users will have to select the configs manually to get a bootable image
for RZ/Five.

Ya, I agree.  If we end up with another RZ/Five or somone gets rid of 
that DMA pool stuff that's forcing the NONPORTABLE then we can always 
re-add it.

I picked this one up and send the ARCH_RENESAS removal.
