The first patch moves spi-orion to use the spi setup/set_cs/transfer_one function pointers, which reduces duplicated code, and simplifies the chip select support implementation. The second patch adds support for multiple chip selects. Currently there is no additional support for gpio chip selects, as I do not have a board to test that with. These patches have been tested on an Armada 375 with 2 SPI-NOR chips.
