This patchset adds support for optional memory-mapped flash reading. BTW: This controller is a ridiculous one which only supports very limited spi-nor instructions. I can't rework the driver into a spi-mem one because MTK didn't provide register description in their datasheet and even if they do provide the documentation, the resulted driver will still be ridiculous because it'll need to check every supported instructions in support_op and do execution in one-by-one case in exec_op.
