Hello all:
	We have get the schematic from Steven.
I have some question about the driver in ppcboot and
linux.

1.Why in ppcboot/include/pcmcia.h , all memory windows
have defined same in all boards.These values can be
changed ( if fit with address encode)?
If we just use PCMCIA as IDE , pcmcia_init() will not
been called()?

2.IDE just need a hw_regs_t(via PCMCIA's port) to
access IDE's register and a IRQ , these are enough?

3.If we use normal harddisk(as same in PC), Can this
driver do them?
