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? -- Kind regards, Jens _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
