We have limited demand for platform PATA support across MIPS platforms:

$ find arch/mips -type f | sort | xargs grep -l pata_platform_info
arch/mips/alchemy/devboards/db1200.c
arch/mips/alchemy/devboards/db1300.c
arch/mips/sibyte/swarm/platform.c
$ 

certainly not high enough to justify enabling support for PATA_PLATFORM 
port-wide.  SiByte platforms are handled selectively already, so just 
make a similar arrangement for Alchemy DB1XXX platforms.

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea.                                                [ RFC1925, 2.3 ]
