Hi,

 Earlier this year I noticed the CBUS UART, a discrete TI16C550C part 
wired directly to the system controller's device bus and supposed to come 
up as ttyS2 in addition to ttyS0 and ttyS1 ports from a Super I/O device 
behind the PCI southbridge, is not recognised with my MIPS Malta board 
booting big-endian.

 I got to the bottom of the problem now and as it turns out we have two 
long-standing bugs causing it, one in generic 8250 code and another in 
Malta platform code, and this has never worked in the big-endian mode.  

 Here's v2 of the series, addressing minor issues with 1/2 pointed out in 
the review.

 Please apply.
