Introduce a new mach-qcom that will support SoCs that intend to be
multiplatform compatible while keeping mach-msm to legacy SoC/board
support that will not transition over to multiplatform.
As part of this, we move support for MSM8X60, MSM8960 and MSM8974 over
to mach-qcom.

The DT based MSM platforms can join the multi-platform builds, so
introduce a DT based ARCH_MSM option. This option allows DT based
MSM platforms to be built into the multi-platform kernel. Also
introduce a hidden ARCH_MSM config that both the DT and non-DT
platform support code select to avoid churn in places that depend
on CONFIG_ARCH_MSM.

The TWD and SCU configs are selected by default as long as
MSM_SCORPIONMP is false and/or MCT is false. Implementing the
logic this way certainly saves lines in the Kconfig but it
precludes those machines which select MSM_SCORPIONMP or MCT from
participating in the single zImage effort because when those
machines are combined with other SMP capable machines the TWD and
SCU are no longer selected by default.
Push the select out to the machine entries so that we can compile
these machines together and still select the appropriate configs.

As suggested by Andrew Morton:
This is a pet peeve of mine. Any time there's a long list of items
(header file inclusions, kconfig entries, array initalisers, etc) and
someone wants to add a new item, they *always* go and stick it at the
end of the list.
Guys, don't do this. Either put the new item into a randomly-chosen
position or, probably better, alphanumerically sort the list.
lets sort all our select statements alphanumerically. This commit was
created by the following perl:
while (<>) {
while (/\\\s*$/) {
$_ .= <>;
}
undef %selects if /^\s*config\s+/;
if (/^\s+select\s+(\w+).*/) {
if (defined($selects{$1})) {
if ($selects{$1} eq $_) {
print STDERR "Warning: removing duplicated $1 entry\n";
} else {
print STDERR "Error: $1 differently selected\n".
"\tOld: $selects{$1}\n".
"\tNew: $_\n";
exit 1;
}
}
$selects{$1} = $_;
next;
}
if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or
/^endif/ or /^endchoice/)) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
undef %selects;
}
print;
}
if (%selects) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
}
It found two duplicates:
Warning: removing duplicated S5P_SETUP_MIPIPHY entry
Warning: removing duplicated HARDIRQS_SW_RESEND entry
and they are identical duplicates, hence the shrinkage in the diffstat
of two lines.
We have four testers reporting success of this change (Tony, Stephen,
Linus and Sekhar.)

Making SMP depend on (huge list of MACH_ and ARCH_ configs) is
bothersome to maintain and likely to lead to merge conflicts.
This patch moves the knowledge of which platforms are SMP-capable
to the individual machines. To enable this, a new HAVE_SMP config
option is introduced to allow machines to indicate that they can
run in a SMP configuration.

SCM is the protocol used to communicate between the secure and
non-secure code executing on the applications processor. The
non-secure side uses a physically contiguous buffer to pass
information to the secure side; where the buffer conforms to a
format that is agreed upon by both sides. The use of a buffer
allows multiple pending requests to be in flight on the secure
side. It also benefits use cases where the command or response
buffer contains large chunks of data.

Add the 'gpiomux' api, which addresses the following shortcomings
of existing tlmm api:
- gpio power-collapse, which is managed by a peripheral processor on
other targets, must be managed by the application processor on the 8x60.
- The enable/disable flag of the legacy gpio_tlmm_config api
is not applicable on the 8x60, and causes confusion.
- The gpio 'direction' bits are meaningless for all func_sel
configurations except for generic-gpio mode (func_sel 0), in which
case the gpio_direction_* functions should be used. Having these
bits in the tlmm api leads to confusion and misuse of the gpiolib
api, and they have been removed in gpiomux.
- The functional api of the legacy system ran contrary to the typical
use-case, which is a single massive configuration at boot. Rather
than forcing hundreds of 'config' function calls, the new api
allows data to be configured with a single table.
gpiomux_get and gpiomux_put are meant to be called automatically
when gpio_request and gpio_free are called, giving automatic
gpiomux/tlmm control to those drivers/lines with simple
power profiles - in the simplest cases, an entry in the gpiomux table
and the correct usage of gpiolib is all that is required to get proper
gpio power control.
