Hi Samuel,
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.
many thanks for sending this, indeed our Kconfig deserved some cleanups, plus we need to fix the woes with RISC-V. I just skimmed over this for now, and it seems to look good.
I have some gripes with the name BOARD_SUNXI though. Bad enough we have board-agnostic generic code in board/sunxi, but maybe we shouldn't add to the confusion. Would PLAT_SUNXI be a better name? After all it's all about the Allwinner platform (and not even "architecture", for that matter).
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.
Yeah, I will definitely cherry-pick some patches, especially the more innocent ones. I will run my before/after defconfig comparisons to test them.
Cheers, Andre
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: https://github.com/smaeul/u-boot/commit/c12cf6c5d72f5327eff793518229ddbd41dc...
Adding SUNXI_MINIMUM_DRAM_MB certainly made things nicer. There are a few options that probably still need some adjustment to respect it.
