32-bit ARM kernels may have a 64-bit dma_addr_t but have no
implementation of the compiler helper for 64-bit unsigned division,
therefore the use of the modulo operator in pl330_prep_dma_memcpy causes
the link error "undefined reference to `__aeabi_uldivmod'"
As the burst value is always a power o
8 matches
