Hi Martin,

The Radxa Rock 4D exists also with a different SPI flash chip than the
one specified in the schematic[1]: XMC XM25QU128C.
At least board revision V1.12 can be impacted.
Enable CONFIG_SPI_FLASH_XMC Kconfig options.
Without this SPL fails to probe the SPI and thus fails to load u-boot
the SPI flash
proper from SPI.
Vendor u-boot also enables CONFIG_SPI_FLASH_GIGADEVICE and
CONFIG_SPI_FLASH_WINBOND so other hardware configuration might exist.
They are not enabled by this patch.
This patch here matches what's been done in Radxa downstream U-Boot in
commit 2742c75cc288 ("configs: rk3576 series: enable
CONFIG_SPI_FLASH_XMC") so fine with me. However, it doesn't apply. I'm
assuming the issue is the CONFIG_SPI_FLASH_MACRONIX=y line being split
in two in the git context just above the new CONFIG_SPI_FLASH_XMC=y
line. Can you please send a v2 with a patch that can be applied?
Try to properly capitalize U-Boot while at it :)
Cheers,
Quentin
