The iVDR clock enable bit happens to actually reside in a rather
different place than what is documented, so fix it up accordingly.
This fixes up SATA boot for some of the R7780RP boards that didn't
default-enable the clock in the loader.

This allows the baud rate for earlyprintk for sh4 without the
standard BIOS to be set via the command line. This uses the same
format as i386 and x86_64, which is:

	earlyprintk=serial,ttySC1,38400

The second parameter (ttySC1 above) is usually the console device
name or the io address of the serial port. I allow that to be
specified but ignore it in order to keep the format the same as
i386/x86_64.

syscall number 300 fails while testing with latest LTP
(ltp-full-20061121.tgz) on sh.

sys_fstatat64 is called on syscall 300 (see arch/sh/kernel/syscalls.S),
and __ARCH_WANT_STAT64 is defined in include/asm-sh/unistd.h, so
following patch seems correct.

This rips out most of the needlessly complicated sh_bios and kgdb
trap handling, and forces it all through a common fast dispatch path.
As more debug traps are inserted, it's important to keep them in sync
for all of the parts, not just SH-3/4.

As the SH-2 parts are unable to do traps in the >= 0x40 range, we
restrict the debug traps to the 0x30-0x3f range on all parts, and
also bump the kgdb breakpoint trap down in to this range (from 0xff
to 0x3c) so it's possible to use for nommu.

Optionally, this table can be padded out to catch spurious traps for
SH-3/4, but we don't do that yet..

This reverts some bogosity from the dynamic command-line
changes made on sparc32 and sparc64.

Drivers such as drivers/sbus/char/openprom.c reference
saved_command_line, and can be modular.

The boot_command_line is __initdata, yet the dynamic command-line
changes add modular exports of that symbol, obviously wrong.
