Did you change wait_for_bit function with _le32? [1]

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?
Vignesh, I think there's an ongoing discussion about this on the u-boot list to fix this?
didn't get what issue Vignesh, pointing at but with new wait_for_bit need a fix[2] to resolve warnings.

Yes, above patch should help to get rid of warnings. I will rebase, test and resend.
