Hi,
I download a 2.6.8 Linux kernel to port it to a custom 8560 board
similar to MPC8560_ADS board..
In the arch/ppc/boot directory there is no 85xx_io directory with
a CPM uart driver.
The kernel link waits for some serial basic functions like serial_getc().
I found the generic ./drivers/serial/cpm_uart driver, but it seems to only
be
used later when Linux is installed.
Surely I miss something.
How can I have a console for my boot ?
Are 8260 cpm2 definitions compatible with 85xx ?
Thanks

The common boot code in the kernel has not been ported to e500 or 85xx.
Thus the lack of proper serial support for the 8560. I would recommend
using u-boot as the boot loader. U-boot already has support for the
8560 and several boards.
