I just made the multi-port work on db1550. The problem is due to the
misplacement of the UART register. So if anybody else want to run
other boards on db1550, make sure you use the UART register address of
your "own boards", not au1000.h. Thanks for the help.

Now I am trying to support a IDE/CompactFlash adapter. I patched the
kernel as other mentioned, forcing HPT371N to use the timing of
HPT372N. But got no luck to succeed.  The output is:

Uniform Multi-Platform E-IDE driver Revision: 7.00beta4-2.4
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
HPT371: IDE controller at PCI slot 00:0b.0
HPT371: chipset revision 2
HPT371: not 100% native mode: will probe irqs later
hpt: HPT372N detected, using 372N timing.
FREQ: 73 PLL: 35
hpt: no known IDE timings, disabling DMA.

Any idea what is happening here?
