Various U-Boot adoptions/extensions to MTD/NAND/UBI did not take buffer alignment into account which led to failures of the following form:
ERROR: v7_dcache_inval_range - start address is not aligned - 0x1f7f0108 ERROR: v7_dcache_inval_range - stop address is not aligned - 0x1f7f1108

What about using ALLOC_CACHE_ALIGN_BUFFER() and friends instead ? See include/common.h for their definition, this is what those functions are exactly for.
ALLOC_CACHE_ALIGN_BUFFER() is for statically allocating an aligned buffer. Dynamically allocating an aligned buffer is exactly what memalign() is for.
