This provides a unified configuration across all sunxi boards,
regardless of CPU architecture.

sunxi: Prepare platform Kconfig to support multiple architectures
sunxi is getting a new RISC-V platform, D1. We want to share as much of
the existing configuration as possible, to provide a familiar
environment, DRAM layout, partition layout, etc.
Because U-Boot includes all architecture Kconfig files at once, we must
use a symbol outside of both CONFIG_ARM and CONFIG_RISCV to contain
shared Kconfig options. I chose BOARD_SUNXI, corresponding to the file
location and somewhat following the BOARD_SPECIFIC_OPTIONS pattern.
I did a buildman run on this series. The only net option changes are the
expected ones:
- Host-side USB gets enabled on several boards by the first patch
(emlid_neutis_n5_devboard orangepi_zero2 pinephone pinetab tanix_tx6
x96_mate teres_i)
- CONFIG_BOARD_SUNXI gets added everywhere
- CONFIG_SYS_I2C_MVTWSI gets enabled by the corresponding patch
Andre, please feel free to take any subset of these; they don't all have
to go in at once. And I'm open to suggestions about what instances of
ARCH_SUNXI should (not) be converted. Some of them are open to opinion.
I left alone the options in arch/arm/mach-sunxi/Kconfig that are covered
by other series (MMC CD/USB PHY/power pins, AXP GPIO).
After this series, the Kconfig changes needed for D1 support are quite
small, something like this commit:
c12cf6c5d7.patch
Adding SUNXI_MINIMUM_DRAM_MB certainly made things nicer. There are a
few options that probably still need some adjustment to respect it.
