Does the current version Mvista preview 2.1 fully support serial mode of 107 EPIC ? If so, what is interrupt number for serial mode interrupt 0 of mpc107 ? I reviewed the old messages on this list and the open_pic.c and there are some threads talking about the first 16 interrupts are reserved for 8259 only. Does that mean serial mode interrupt 0 match interrupt 16 on open_pic interrupt table ?
Plus, I changed the base address of boot/common/ns16550.c to drive the TI 752 uart. It appears working before kernel starts. Then it hang. It seems that the same file (ns16550.c) is not used after kernel starts. Which serial device driver is used after kernel starts ? Starting at 0x800000... loaded at: 00800000 0089E1BC zimage at: 00805870 0089AC70 avail ram: 00400000 00800000 Linux/PPC load: Uncompressing Linux...done. Now booting the kernel Thanks.
