  mtd: rawnand: sunxi_spl: Fix cast to pointer from integer warnings
(2026-01-19 10:25:16 +0100)

This series provides a comprehensive cleanup of the Allwinner (sunxi)
NAND controller drivers and
introduces full support for the H6 and H616 SoCs in both the main
U-Boot driver and the SPL.

The series successfully deduplicates register maps between
sunxi_nand.c and sunxi_nand_spl.c
while migrating to a capability-based architecture. This approach
allows the driver to handle
the H616's specific requirements—such as shifted register offsets for
ECC/OOB, the removal of
512B ECC block support, and mandatory MBUS clock gating—without
breaking compatibility
for legacy A10/A23 devices.

The patches pass the pipeline CI:
