Yes, I am building plain u-boot-spi/master(HEAD: 0f520af57c60f3baba8
("spi: kirkwood_spi: implement workaround for FE-9144572")). So, above
commit is part of the tree.

Problem is above commit adds
BUILD_WAIT_FOR_BIT(be32, u32, read*_be) variants.
But, readl_be and readw_be seems to be undefined for ARM?
