I need to set PSC3 - PSC4 in uart mode:
before in file *arch/ppc/platforms/lite5200.c* I added

struct mpc52xx_psc_func mpc52xx_psc_functions[] = {
        {       .id     = 3,
                .func   = "uart",
        },
        {       .id     = 4,
                .func   = "uart",
        },
        {       .id     = -1,   /* End entry */
                .func   = NULL,
        }
};

I need to set PSC4 as a low level debug: *
*before in file *arch/ppc/platforms/lite5200.h *I added

#define MPC52xx_PF_CONSOLE_PORT 4    /* PSC4 */

Finally I need to set the virtual memory translation on a range of 128 MB:
before in file *arch/ppc/kernel/head.S *I added

/*ori    r11,r11,BL_128M<<2|0x2    set up BAT registers for 604 */

ori    r11,r11,BL_128M<<2|0x2    /* set up BAT registers for 604 */

could you please explain me how to do the same operations in powerpc tree??

thanks Fabio

Hello, I have an embedded system with an on-board processor powerpc MPC5200B

 I must turn over to MMC SPI on the PSC6.

 First, I
 have enabled PSC6:

 in ../arch/ppc/platforms/lite5200.c added PSC6 in SPI mode


You're using arch/ppc which is depreciated.  You should move to using
arch/powerpc (set ARCH=powerpc when compiling).  Devices are then
enabled in the device tree source file
arch/powerpc/boot/dts/lite5200b.dts.

Many things have changed with MPC5200 support in the last year, you
should also use the latest kernel release (2.6.25.2 when it is
released.  If you use 2.6.25.1, then there is a trivial bug in the psc
serial port driver that you'll need to fix.  I'll include the link to
the patch below)

Cheers,
