From 9ceb0a3e0cde6bbac2c4cee7ae18e9e1d7d33858 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Fri, 8 May 2026 10:01:40 +0200 Subject: sunxi: spl: spi: Add support for Allwinner A523 The SPI IP in the Allwinner A523 is mostly compatible to the later generation used in other Allwinner SoCs, at least as far as the SPL driver is concerned. Just add the pinmux configuration for SPI0 on PortC, as used by the BROM. This enables SPI (NOR) boot on A523/A527/T527 boards.
