I am also wondering about commit f85764cc1f6ab01ffc60dd78de9c4de4cff2b5ce, which
defines CONFIG_SPI_FLASH in the WRU4 defconfig file, even though it does not
need SPI flash support, just to work around undefined reference errors regarding
spi_flash_free, etc.
Couldn't those workarounds be avoided by excluding the SPI parts via ifdefs, as
I did in my patch today?
