unfortunately I have to push this message, as I received no comment on it, yet.
Is there a reason why the immap_t is not implemented for mpc85xx?
I tried to copy it from mpc8360 but there are so many dependent mpc83xx datatypes in that struct that I postponed the work on that, because I think it'll lead to no success...
Even trying to use the soft SPI fails, because first thing the code does is using that immap_t datatype... :-(
Does anyone have a comment on this?
I took a quick glance at this. There are different versions of SPI controllers in the MPC8xxx SoC's. As it seems mpc8xxx_spi.c does "only" support the "CPU- mode" (meaning non-CPM/QE-mode) Freescale SPI controllers. This controller is implemented for example in the MPC8349. For your SoC (MPC8568) you need to implement the QE-mode which is currently not supported.
I didn't compare the MPC85xx QE SPI controller with the MPC8xx CPM SPI controller, but maybe a look at arch/powerpc/cpu/mpc8xx/spi.c could help you as a base for porting/creating a driver?
