One of the key differences between my uartlite driver and Peter's
is that like many other serial drivers I have a timer to support irqless
use. Just like Peter has UartLite Like devices with 16bit datapaths,
I have UartLites with no interrupts.
I have tried (unsuccessfully) several times to migrate my timer
code into Peter's driver. This is probably the most fundimental
remaining reason I can not use Peter's driver.
More recently I noticed a CONFIG_CONSOLE_POLL option show
up. There are remarks that this is similar to NETPOLL - though
it seems to be implimented using a getc and putc rather than a
poll entry.
Is this a general serial facility, rather than just for consoles ?
If I create the polled getc/putc routines can I expect a serial driver
to be functional without having to implement my own timer based
polling ?
Is this the proper way to do this ?
