[PATCH 1/3] sunxi: board: simplify early PMIC setup conditions

[Leon Anavi]

Hi,

Commit ffb0294 from 12 November 2023 that simplifies early PMIC setup
conditions causes issues on Cubieboard 4 and Merrii A80 Optimus with
Allwinner A80 SoC (sun9i). The commit was introduced with U-Boot 2024.01
(rc3) and remains as of today. Because of it both of these boards hang at:

Starting kernel ...

Older U-Boot versions without this commit work fine. As a temporary
solution I reverted commit ffb0294 and this way the boards boot
successfully. I tested this work around on Merrii A80 Optimus with several
U-Boot versions, including with U-Boot 2024.10.

Lazar, a friend who owns Cubieboard 4, also tested and confirmed his board
boots with U-Boot 2024.10 if this commit has been reverted.

How to fix this? Is there a known configuration that can be added to
Merrii_A80_Optimus_defconfig and Cubieboard4_defconfig to avoid hanging
with the existing source code from commit ffb0294 ?

Best regards,
Leon
