-Subject: [PATCH 112/113] driver: spi: fsl-quad: Hang memcpy: Unhandled fault:
- alignment fault
-
-vmap/iomap based on whether the buffer is in memory region or reserved region.
-However, both map it as non-cacheable memory.
-For armv8 specifically, non-cacheable mapping requests use a memory type
-that has to be accessed aligned to the request size. memcpy() doesn't guarantee
-that. memcpy_toio() can guarantee 4-bytes alignment.
