This is one of the hackiest Alpha machines, and the only one without
PCI support. Removing this allows cleaning up code in eise and tty
drivers in addition to the architecture code.

On suspend/resume cycle, selftest is executed to reset i8042 controller.
But when this is done in Asus devices, subsequent calls to detect/init
functions to elantech driver fails. Skipping selftest fixes this problem.
An easier step to reproduce this problem is adding i8042.reset=1 as a
kernel parameter. On Asus laptops, it'll make the system to start with the
touchpad already stuck, since psmouse_probe forcibly calls the selftest
function.
This patch was inspired by John Hiesey's change[1], but, since this problem
affects a lot of models of Asus, let's avoid running selftests on them.
All models affected by this problem:
A455LD
K401LB
K501LB
K501LX
R409L
V502LX
X302LA
X450LCP

i8042_platform_init() skips reguest_region() on MIPS, but in
i8042_platform_exit() release_region() is still called. Fix this by
reserving the region also on MIPS.
The patch eliminates the following error message seen on MIPS:
[ 2.112000] Trying to free nonexistent resource <0000000000000060-000000000000006f>

Currently the irqs for the i8042, which historically provides keyboard and
mouse (aux) support, is hardwired in the driver rather than parsing the
dts. This patch modifies the powerpc legacy IO code to attempt to parse
the device tree for this information, failing back to the hardcoded values
if it fails.

Now that arch/ppc is dead CONFIG_PPC_MERGE is always defined for all
powerpc platforms and we want to get rid of CONFIG_PPC_MERGE use
CONFIG_PPC instead.

ppc can boot one single binary on prep, chrp and pmac boards. ppc64 can
boot one single binary on pseries and G5 boards. pmac has no legacy io,
probing for PC style legacy hardware (or accessing the legacy io area
regulary) may lead to a hard crash:
* add check for parport_pc, exit on pmac. 32bit chrp has no
->check_legacy_ioport, the probe is always called. 64bit chrp has
check_legacy_ioport, check for a "parallel" node
* add check for isapnp, only PReP boards may have real ISA slots. 32bit
PReP will have no ->check_legacy_ioport, the probe is always called.
* update code in i8042_platform_init. Run ->check_legacy_ioport first,
always call request_region. No functional change. Remove whitespace
before i8042_reset init.

Some people report that we die on some Macs when we are expecting to
catch machine checks after poking at some random I/O address. I'd seen
it happen on my dual G4 with serial ports until we fixed those to use
OF, but now other users are reporting it with i8042.
This expands the use of check_legacy_ioport() to avoid that situation
even on 32-bit kernels.

This patch adds sh64 support.
This is a bit overdue, as this was on the should-fix list, though we
weren't done debugging and finishing off the port until just recently (I
did a port against 2.5.68 but it wasn't in any shape to be merged).
sh64 is already in 2.4 and has been for quite awhile, so this is mostly
just a forward port of that code to 2.6 with appropriate bug fixes, etc.
along the way. There isn't much in the way of new features that have been
added to the port yet, though I have added rough hugetlb and oprofile
support.
This patch doesn't really touch any common code, with the exception of an
ifdef or two for keyboard support and an ifdef in fb.h to omit sh64 from
the __raw_xxx() wrapping that sh does.
The only other common driver changes were to sh-sci for serial support, but
those bits were already merged with the latest batch of sh-sci updates.
Beyond that, the port is completely isolated.
