On some firmwares we have to tell how exactly we want the command to be
proceeded. The default case, based on the official BSP code, is to run it
immediately.
This appears to be a safer approach based on the documentation.

Historically a lot of these existed because we did not have
a distinction between what was modular code and what was providing
support to modules via EXPORT_SYMBOL and friends. That changed
when we forked out support for the latter into the export.h file.
This means we should be able to reduce the usage of module.h
in code that is obj-y Makefile or bool Kconfig. The advantage
in doing so is that module.h itself sources about 15 other headers;
adding significantly to what we feed cpp, and it can obscure what
headers we are effectively using.
Since module.h was the source for init.h (for __init) and for
export.h (for EXPORT_SYMBOL) we consider each obj-y/bool instance
for the presence of either and replace as needed.
One module.h was converted to moduleparam.h since the file had
multiple module_param() in it, and another file had an instance of
MODULE_DEVICE_TABLE deleted, since that is a no-op when builtin.
Finally, the 32 bit build coverage of olpc_ofw revealed a couple
implicit includes, which were pretty self evident to fix based on
what gcc was complaining about.

Intel MID platforms are using explicitly defined regulators.
Let the regulator core know that we do not have any additional
regulators left. This lets it substitute unprovided regulators with
dummy ones.
Without this change when CONFIG_REGULATOR=y the USB driver fails on getting
"vbus" regulator and SDHCI can't get "vmmc" and "vqmmc" regulators either.

Intel Penwell is one of the first SoCs in Intel MID series. It has slightly
older version of PWRMU IP, though it is compatible with one found on Intel
Tangier. Since we are not using (yet) any advanced stuff in the driver we may
safely re-use what it's done for Intel Tangier for now.
Extend PWRMU driver to support Intel Penwell by adding PCI ID and re-using
existing ->set_initial_state() function.

Drivers should not really include stuff from asm-generic directly,
and the PC-style cmos rtc driver does this in order to reuse the
mc146818 implementation of get_rtc_time/set_rtc_time rather than
the architecture specific one for the architecture it gets built for.
To make it more obvious what is going on, this moves and renames the
two functions into include/linux/mc146818rtc.h, which holds the
other mc146818 specific code. Ideally it would be in a .c file,
but that would require extra infrastructure as the functions are
called by multiple drivers with conflicting dependencies.
With this change, the asm-generic/rtc.h header also becomes much
more generic, so it can be reused more easily across any architecture
that still relies on the genrtc driver.
The only caller of the internal __get_rtc_time/__set_rtc_time
functions is in arch/alpha/kernel/rtc.c, and we just change those
over to the new naming.

Pull module_init replacement part one from Paul Gortmaker:
"Replace module_init with equivalent device_initcall in non modules.
This series of commits converts non-modular code that is using the
module_init() call to hook itself into the system to instead use
device_initcall().
The conversion is a runtime no-op, since module_init actually becomes
__initcall in the non-modular case, and that in turn gets mapped onto
device_initcall. A couple files show a larger negative diffstat,
representing ones that had a module_exit function that we remove here
vs previously relying on the linker to dispose of it.
We make this conversion now, so that we can relocate module_init from
init.h into module.h in the future.
The files changed here are just limited to those that would otherwise
have to add module.h to obviously non-modular code, in order to avoid
a compile fail, as testing has shown"

The X86_INTEL_MID option is bool, and hence this code is either
present or absent. It will never be modular, so using
module_init as an alias for __initcall is rather misleading.
Fix this up now, so that we can relocate module_init from
init.h into module.h in the future. If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.
Note that direct use of __initcall is discouraged, vs. one
of the priority categorized subgroups. As __initcall gets
mapped onto device_initcall, our use of device_initcall
directly in this change means that the runtime impact is
zero -- it will remain at level 6 in initcall ordering.

MID has no PIC, but depending on the platform it requires the
abt_timer, which is connected to irq0. The timer is set up at
late_time_init().
But, looking at the MID code it seems, that there is no reason to do
so. The only code which might need the timer working is the TSC
calibration code, but thats a non issue on MID as that is using its
own empty calibration function. And check_timer() is not invoked
either because MID has no PIC and therefor no legacy irqs.
So if you look at intel_mid_time_init() then you'll see that in the
ARAT case the timer setup is skipped already. So until the point where
x86_init.timers.setup_percpu_clockev() is called for the boot cpu
nothing really needs a timer on MID.
According to the MID code the apbt horror is only used for moorestown.
Medfield and later use the local apic timer without the apbt nonsense.
The best thing we can do is to drop moorestown support and get rid of
that apbt nonsense alltogether.
I don't think anyone deeply cares about it not being supported from
3.18 on. The number of devices which sport a moorestown should be
pretty limited and the only relevant use case of those is to act as a
pocket heater with short battery life time. Its pretty pointless to
update kernels on pocket heaters except for bragging reasons.
If someone at Intel really thinks that we need to keep moorestown
alive for other than documentary and sentimental reasons, then we can
move the apbt setup to x86_init.timers.setup_percpu_clockev(). At that
point the IOAPIC is setup already, so it should just work.

Since we have a native 8250 driver carrying the Intel MID serial devices the
specific support is not needed anymore. This patch removes it for Intel MID.
Note that the console device name is changed from ttyMFDx to ttySx.

__FUNCTION__ hasn't been treated as a string literal since gcc 3.4, so
this only helps people who only test-compile using 3.3 (compiler-gcc3.h
barks at anything older than that). Besides, there are almost no
occurrences of __FUNCTION__ left in the tree.

Intel Moorestown platform support was removed few years ago. This is a follow
up which removes Moorestown specific code for the serial devices. It includes
mrst_max3110 and earlyprintk bits.
This was used on SFI (Medfield, Clovertrail) based platforms as well, though
new ones use normal serial interface for the console service.

Intel MID platforms has no legacy interrupts, so no IRQ descriptors
preallocated. We need to call mp_map_gsi_to_irq() to create IRQ
descriptors for APB timers and RTC timers, otherwise it may cause

interface io_apic_set_pci_routing(), so change arch/x86/platform/
intel-mid/device_libs/platform_wdt.c to use new interfaces.
Due to hardware resource restriction, this patch only passes compilation

Enhance SFI to provide basic support of irqdomain with identity mapping
between GSIs and IRQs.
Some Intel MID platforms assumes identity mapping between GSI and IRQ,
so we can't dynamically allocate IRQ number on demand.

Commit bc20aa48bbb3068224a1c91f8332971fdb689fad ("x86, intel-mid:
Add Merrifield platform support") added new instances of __cpuinit
usage. We removed this a couple versions ago; we now want to remove
the compat no-op stubs. Introducing new users is not what we want to
see at this point in time, as it will break once the stubs are gone.
This also fixes an out of sync __init vs. __cpuinit -- as the former
is real, and the latter is a no-op; hence it would have been a section
mismatch.

When Intel MID finds a match between SFI table from FW and registered
SFI devices, it will always register a device regardless the platform
code was successful or not.
This patch adds an extra option for platform code to return error code
and abort device registration on SFI table parsing.
This patch does not contain any functional changes for current intel
mid platform code.
