[coreboot] and/or busybox issue with alix2c3 serial console

[ron minnich]

This makes no sense at all. I would have guessed that busybox workd
and voyage did not!

voyage:
cat /proc/tty/driver/serial

serinfo:1.0 driver revision:
0: uart:16550A port:000003F8 irq:0 tx:4513 rx:139 oe:3 RTS|CTS|DTR|DSR|CD
1: uart:unknown port:000002F8 irq:3


cat /proc/interrupts

           CPU0
  0:     265852    XT-PIC-XT        timer
  2:          0    XT-PIC-XT        cascade
 10:        116    XT-PIC-XT        eth0
 11:          1    XT-PIC-XT        ehci_hcd:usb1, ohci_hcd:usb2

ok, uart has irq 0 and there is no irq for it.

busy:
cat /proc/tty/driver/serial

serinfo:1.0 driver revision:
0: uart:16550A port:000003F8 irq:4 tx:0 rx:0 RTS|CTS|DTR|DSR|CD
1: uart:unknown port:000002F8 irq:3


cat /proc/interrupts

           CPU0
  0:       6011    XT-PIC-XT        timer
  2:          0    XT-PIC-XT        cascade
  4:          0    XT-PIC-XT        serial

actually makes sense and compares to factory:
serinfo:1.0 driver revision:
0: uart:16550A port:000003F8 irq:4 tx:825 rx:7 RTS|CTS|DTR|DSR|CD
1: uart:unknown port:000002F8 irq:3


cat /proc/interrupts

           CPU0
  0:      11770    XT-PIC-XT        timer
  2:          0    XT-PIC-XT        cascade
  4:         70    XT-PIC-XT        serial

but voyage gets this:
Console: colour dummy device 80x25
console [ttyS0] enabled

busy gets
Console: colour dummy device 80x25
console [tty0] enabled
console [ttyS0] enabled

busy+v3 gets
Console: colour dummy device 80x25
console [ttyS0] enabled

oh boy. . voyage/v3 gets this:
Serial: 8250/16550 driver $Revision: 1.90 $ 2 ports, IRQ sharing enabled
�serial8250: ttyS0 at I/O 0x3f8 (irq = 0) is a 16550A

this is I am pretty certain an IRQ foulup. Why are busy and voyage so
totally different?

how do the .config files compare? does factory bios have ACPI (it
would appear not).
