443 reg = cpu_to_be32(*pdata);
444 writel(reg, ebu_host->hsnand + HSNAND_CMSG_1);
On BE:
cpu_to_be32 -> no-op
writel() -> converts reg to LE
On LE:
cpu_to_be32 -> converts to BE
writel() -> no-op (in terms of conversion)
Seems to me that the proper API (if above is intended) should be swab32().
But something tells me that above is broken (or my understanding is wrong).
