a little patch (against «linux-2.6.16-stable» branch and tested on
au1100 based board) to fix the addresses specification for the serial
driver. With this patch at boot time we get:

Serial: 8250/16550 driver $Revision: 1.90 $ 3 ports, IRQ sharing disabled serial8250.7: ttyS0 at MMIO 0x11100000 (irq = 0) is a 16550A serial8250.7: ttyS1 at MMIO 0x11200000 (irq = 1) is a 16550A serial8250.7: ttyS2 at MMIO 0x11400000 (irq = 3) is a 16550A

I have already noticed and fixed this. The fix is in Andrew Morton's tree (unpublished yet). See this msg for the patch:

   This is not quite correct. The UARTs take up 1 MB of memory each.



WBR, Sergei
