Sorry for follwing up 2 month ago, I just happen to stumble on some
I was going to type "3 months ago" since 3 months have apssed indeed. :-<
issues addresses by these patches as well. I assume you haven't tried
sending them to Russel King?
Not yet, I just waiting for some comments. :)
Now you have some at last. :-)

NAK. readl() can't be used to read from Alchemy SOC peripherals because
it'll break in BE mode. Alchemy automagically handles byteswap for the SOC
peripherals.
Ok. I'm going to fix it by using au_readl() but in this case I have to
add an ifdef with au1xxx include file. Can it be acceptable?
I think so. But it's Russel who will decide. :-)

I'd simply map UPIO_AU to "MMIO" in the message because it's memory
mapped UART after all...
Yes, but in the kernel command line we must supply "au"... That's why
I used different string, so the user can verify whatever he/she passed
to the kernel.
I can also suggest something like "Au1xx0 MMIO"... :-)

Also needs cases for UPIO_MEM32 and UPIO_TSI.
I just added the code for au1xxx. Why should I consider those cases
also?
It seems that you can remove this hunk altogether now -- Russel has
accepted my patch adding cases for UPIO_MEM32, UPIO_AU and UPIO_TSI...
-#ifdef CONFIG_SERIAL_8250_AU1X00
case UPIO_AU:
- __raw_writel(value, up->port.membase + offset);
+ writel(value, up->port.membase + offset);
break;
-#endif
Ditto writel().
Is __raw_writel() correct?
It should be.
Thanks for your suggestions.
Ciao,
Rodolfo
