Series sunxi: improve F1C200s support | expand


Andre Przywara Oct. 12, 2022, 4:34 p.m. UTC
The Allwinner F1C200s is reportedly the same chip as the F1C100s, just
with twice the amount of co-packaged DRAM: 64MB instead of just 32MB.
U-Boot's F1C100 platform supported this quite naturally (since the DRAM
size is auto-detected), but those better chips do not need to suffer
from the same memory constraints as their smaller siblings.

Patch 1/6 adds a notion of "minimum DRAM size" to Kconfig, so that we
can select those smaller sizes independently from the actual SoC. This
makes it easy to let the F1C200s use a more generous memory map, but
also paves the way for the T113-S3 and D1s, later.
Patch 2/6 uses the opportunity to improve the 32MB memory map, which was
not really practical, and arguably also somewhat buggy.
Patch 3/6 helps to keep the _defconfig files small, while patch 4+5 add
support for the console on UART1.
The final patch then adds a defconfig and .dts file for the CherryPi
F1C200s board, which is used as an example for a F1C200s board.

Please have a look and test, if possible.
