This series enables the SPI booting feature for Allwinner R40 and H6 SoCs. To achieve this, we enable our spl_spi_sunxi.c driver to deal with those two SoCs. The R40 is pretty straightforward, as it just needs its base address adjusted. This is prepared in patch 1/5 and finalised in patch 3/5. For the H6, on top of yet another different base address, the new clocks and slightly different pinmux setup need to be cared for. Patch 2/5 and 4/5 take care of that. Patch 5/5 enables this feature for the Pine H64 board, which comes with soldered SPI flash.
This has been tested on the Pine H64 board and a Bananapi M2 Berry (with SPI flash connected to the SPI0-PortC header pins). For the existing SPI boot platforms this does not change the code size, as the toolchain is clever enough to optimise this properly.
There is a similar series to enable SPI support for the sunxi-fel tool, which was used to test this: https://github.com/linux-sunxi/sunxi-tools/pull/129
Cheers, Andre.
