It's easy to make ISA bridge.  However, some ISA board (or PCI board)
has initialization program written in x86.  For example, most ISA VGA
adapter has ROM with the board, and we can't use it.  Well, low
priority, though.

You know, some nortebook computer has the feature of "Hibernation", 
let the RAM image go into the disk.  This entry is for that.

Takeshi Yaegashi is using MTD intensively, and he found that
it's need more tweak, especially for "write" operation.

To use PCMCIA feature on SH-4, we need to use MMU, because some bits
are assigned to the bit on TLB to access PCMCIA (area 5 and 6).  We
think that such initialization of the specific hardware (the bus) is
the job of initialization routine (BIOS).  Currently, the kernel
assumes BIOS doesn't use MMU and flush out all the TLB on boot, which
is not good.

For Binutils and GCC, the changes are already incorporated into
current development repository.  Now we need to test and check again.

I think that I've done the fix.  Next, we need to keep up the transition
of the development kernel, please look at Documentation/cachetlb.txt in
test8-pre1.
