Hello Dan, Originally I was referring to both kernel.org and Denx. But I was referred to a patched 2.4.20 version from Denx that enables SCC1 and SCC4 as uarts including RTS, CTS, DCD and DTR pin configuration.
I believe this should go into the kernel from kernel.org. If one chooses to use the 860(T/DT) or 855(T) processors why shouldn't he use SSC1 and 4 as uarts. The limitation of the 857 should not limit other processors. Look at the 852(T), it can use SCC4 as a uart. Regarding the baud rate generators, we can configure the to more then one uart, if those uarts use the same baud rate. So, perhaps the BRG's should be decoupled from the uart in the configuration. This will go to the 8xx CPM configuration witch is processor specific in the first place (FEC, SCC and Ethernet and other 8xx processor variant stuff).

Ummmm....2.4.20 from where? The linuxppc 2.4 development tree was updated by Gary Thomas a while back to allow all possible SMC/SCC configurations within the resource limitations of the particular processor variant. This included the baud rate generator restrictions on the 857. -- Dan ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
