cpm_uart: WARNING: no UART devices found

My board has an MPC880 and it is named TL880 with a linux 2.6.19, I
copied kernel configurations from the very similar board mpc885ads.
I filled in platform data in file TL880_setup.c but I see that function
TL880_fixup_uart_pdata is never called and, as a consequence, I see the
message cpm_uart: WARNING: no UART devices found. Also I receive
message: IP-Config: No network devices available. 
 
 
Bye,
Antonio.

You seem to miss the board ppc_sys_identify_by_name() (or alike) call - so BOARD_CHIP_NAME is 
not defined for your board in BSP file. There is no other way to properly identify SoC with 8xx...

Funny, I just had this problem myself.  After going through and reading
a lot of code, I found out that the macro BOARD_CHIP_NAME must match the
CPU spec in arch/ppc/syslib/mpc8xx_sys.c for the CPU model.  It looks
like trying MPC885 might work.
