Indeed, I did not provide this patch, on purpose.
The SPI-NOR at 4U2 on the P200 schematics was not present on the board
I have. I assumed this was the case for all other P200 as well.
In addition, to enable the SPI-NOR, you would also need to solder
something at 4R3 (SPI_CS signal disconnected by default)
Finally, all the SPIfc lines are shared with the NAND controller which,
like the SPI-NOR, appears on the schematics (4CCN1) but is not soldered
on the actual hardware.
Of course, I can share such patch for testing purposes if you would
like me to.
