I don't know where these came from.  I guess someone modified misc.c?
I don't know what they indicate, either.

I choose to not uncompressing kernel.I modified 8xxrom to load vmlinux
and initrd.
Memory layout is : 0x0-0xd0f94 vmlinux+bdinfo
                   0xc00000-0x1000000 initrd

I will check this.maybe this is the reason.

Don't messages like this get your attention?  Something is wrong with
the memory map, board information structure, or where you loaded the
software kernel and ram disk.

ttyS00 at 0x0100 is a SCC        //i use scc2 as ttyS0

Really?  So, you modified arch/ppc/mbxboot/m8260_tty.c to use an SCC?
You have to make lots of changes to use SCC as a console.  I don't have
any board that uses the SCC for a serial port (easily, without some
hardware hacking), so I haven't tried this.

Why? Because motorola ads board has no smc,so i modified 8xxio/uart.c
.I seems to me that scc can be used as a console and ttyS0 simulataneously.
I cannot find 8260 stuff in kernel.org when i began this port,
now i have pre7,should i read it?I know it is done on a EST board.

Warning: unable to open an initial console.
/*open("/dev/console",...);*/

Not surprised if this is an SCC.  You have some work to contribute :-).

Explain to me why.rs_8xx_open not get called although i registered
it as c 4 64
