I have recently made an attempt to add SPI NAND SPL support: https://lore.kernel.org/u-boot/[email protected]/ And then Jonas pointed out your series.

When I try to build it, I get the following error: drivers/mtd/nand/raw/nand.c:15:34: error: ‘CFG_SYS_NAND_BASE’ undeclared here (not in a function); did you mean ‘CFG_SYS_SDRAM_BASE’? 15 | #define CFG_SYS_NAND_BASE_LIST { CFG_SYS_NAND_BASE } In my SPI NAND case, there is no NAND controller, so no CFG_SYS_NAND_BASE is defined.
