On AM654, McSPI can only support 4K - 1 bytes per transfer when DMA is enabled. Therefore populate master->max_transfer_size callback to inform client drivers of this restriction when DMA channels are available.
As ever this only provides information to other drivers which may be buggy.
I'll drop it, thanks!
