On my target board, I use LPC2220 as processor, there is another Phlips
16C2550B DUART chip.
In my application, I should make use of 4 UART channels.
As I looked over the serial infrastructure of eCos, I think it is hard to
use the "16x5x generic serial device drivers" for both chip concurrently.
1. The "ser_16x5x.c" rely on a "CYGDAT_IO_SERIAL_GENERIC_16X5X_INL", and
this macro has been defined in "ARM LPC2XXX serial device drivers" package.
How to add 16C2550B's description info to "ser_16x5x.c"?
2. "ser_16x5x.c" use "CYGPRI_IO_SERIAL_GENERIC_16X5X_STEP" macro to reflect
delta of UART registers. In LPC2XXX, the UART's register step is 4 bytes,
while on my target board, 16C2550B has been designed with register step 2
bytes. How to solve this condition?
Thanks.
