The global 'tmpbuf' variable in part_iso triggers invalid cache
alignment warnings when not being aligned to ARCH_DMA_MINALIGN:
ERROR: v7_outer_cache_inval_range - start address is not aligned - 0x4ffbb6ac
ERROR: v7_outer_cache_inval_range - stop address is not aligned - 0x4ffbbeac
The quick fix here is to align the global 'tmpbuf' variable using
DEFINE_CACHE_ALIGN_BUFFER. A real fix would be to change part_iso.c to
use function local buffers defined with ALLOC_CACHE_ALIGN_BUFFER.
