The platform was merged about 10 years ago, and has seen few updates
for most of the time since. The people that merged the code seem
no longer interested in it either, so let's remove it now.

There is no defconfig file for gemini, which has lead to a lot
of bitrot. This makes the broken board files, the gpio implementation
and the reset logic work again, and fixes the build warnings
that got introduced with the changes to the readl/writel prototypes.

git://git.linaro.org/people/shawnguo/linux-2.6 into next/cleanup
From Shawn Guo:
The imx cleanup for 3.10:
* Clean up a couple of unneeded function declarations
* Remove imx specific cpufreq driver as generic cpufreq-cpu0 works well
as the replacement
* Remove platform ahci support
* Clean up unused ARCH/MACH Kconfig symbols
* Remove a couple of unused files
* tag 'imx-cleanup-3.10' of git://git.linaro.org/people/shawnguo/linux-2.6:

Select STMP_DEVICE and in timer code replace mxs_reset_block() with
stmp_reset_block(), use STMP_OFFSET_REG_SET/CLR to replace
__mxs_setl/clrl.
As the result, <mach/mxs.h> and <mach/common.h> includsion can be
removed from timer.c now.

Pull SMP/hotplug changes from Ingo Molnar:
"This is a pretty large, multi-arch series unifying and generalizing
the various disjunct pieces of idle routines that architectures have
historically copied from each other and have grown in random, wildly
inconsistent and sometimes buggy directions:
101 files changed, 455 insertions(+), 1328 deletions(-)
this went through a number of review and test iterations before it was
committed, it was tested on various architectures, was exposed to
linux-next for quite some time - nevertheless it might cause problems
on architectures that don't read the mailing lists and don't regularly
test linux-next.
This cat herding excercise was motivated by the -rt kernel, and was
brought to you by Thomas "the Whip" Gleixner."

Just like the OHCI counter part we just can remove the architecture
specific symbols which prevent these configuration symbols from being
selected by platforms/architectures requiring it. The original
implementation did not scale at all since it required each and every
single architecture to be added for these configuration symbols to be
selected. Now it is up to the EHCI driver and/or platform to select
these configuration symbols accordingly.

On Cortex-A15 (r0p0..r3p2) the TLBI/DSB are not adequately shooting down
all use of the old entries. This patch implements the erratum workaround
which consists of:
1. Dummy TLBIMVAIS and DSB on the CPU doing the TLBI operation.
2. Send IPI to the CPUs that are running the same mm (and ASID) as the
one being invalidated (or all the online CPUs for global pages).
3. CPU receiving the IPI executes a DMB and CLREX (part of the exception
return code already).

/.../arch/arm/kernel/pj4-cp0.c:40: undefined reference to `iwmmxt_task_switch'
make: *** [vmlinux] Error 1
This is caused because the PJ4 code explicitly references the iWMMXt
code, but doesn't require it to be built. Fix this by ensuring that
iWMMXt is always enabled with PJ4.

Pull ARM SoC bug fixes from Arnd Bergmann:
"Things are calming down for arm-soc as well. This set of bug fixes is
dominated in size by the at91 platform bug fixes. Some of them were
meant to go through the framebuffer tree during the merge window, but
since the framebuffer maintainer could not be reached, I offered to
take them here. The other notable at91 change is the addition of
pinctrl definitions to fix the NAND controller.
The rest are mostly simple regression fixes:
- Our removal of VIRT_TO_BUS conflicted with Stephen Rothwell's
renaming of the Kconfig symbol. You will get a trivial merge
conflict here, we still want to remove it.
- missing bits for clocks on imx and s5pv210
- missing header inclusions in mmp and shmobile
- typos in s5pv210 camera and vt8500 clock support code
and three trivial fixes for pre-3.8 bugs:
- an old bogus build warning in the joystick driver
- a misleading Kconfig description
- a NULL pointer check on davinci"

887cbce0 "arch Kconfig: centralise CONFIG_ARCH_NO_VIRT_TO_BUS"
and 4febd95a8 "Select VIRT_TO_BUS directly where needed" from
Stephen Rothwell changed globally how CONFIG_VIRT_TO_BUS is
selected, while my own a5d533ee0 "ARM: disable virt_to_bus/
virt_to_bus almost everywhere" was merged at the same time and
changed which platforms select it on ARM.
The result of this conflict was that we again see CONFIG_VIRT_TO_BUS
on all ARM systems. This patch fixes up the problem and removes
CONFIG_ARCH_NO_VIRT_TO_BUS again on ARM.

Rob Herring has observed that c81611c4e96f "xen: event channel arrays are
xen_ulong_t and not unsigned long" introduced a compile failure when building
without CONFIG_AEABI:
/tmp/ccJaIZOW.s: Assembler messages:
/tmp/ccJaIZOW.s:831: Error: even register required -- `ldrexd r5,r6,[r4]'
Will Deacon pointed out that this is because OABI does not require even base
registers for 64-bit values. We can avoid this by simply using the existing
atomic64_xchg operation and the same containerof trick as used by the cmpxchg
macros. However since this code is used on memory which is shared with the
hypervisor we require proper atomic instructions and cannot use the generic
atomic64 callbacks (which are based on spinlocks), therefore add a dependency
on !GENERIC_ATOMIC64. Since we already depend on !CPU_V6 there isn't much
downside to this.
While thinking about this we also observed that OABI has different struct
alignment requirements to EABI, which is a problem for hypercall argument
structs which are shared with the hypervisor and which must be in EABI layout.
Since I don't expect people to want to run OABI kernels on Xen depend on
CONFIG_AEABI explicitly too (although it also happens to be enforced by the
!GENERIC_ATOMIC64 requirement too).

In commit 887cbce0adea ("arch Kconfig: centralise ARCH_NO_VIRT_TO_BUS")
I introduced the config sybmol HAVE_VIRT_TO_BUS and selected that where
needed. I am not sure what I was thinking. Instead, just directly
select VIRT_TO_BUS where it is needed.

Commit 5b03df9ace680d7cdd34a69dfd85ca5f74159d18 ("ARM: dove: switch to
DT clock providers") added "select COMMON_CLK_DOVE" to Marvell Dove's
Kconfig entry. But there's no Kconfig symbol COMMON_CLK_DOVE, which
makes this select statement a nop. It's probably a leftover of some
experimental code that never hit mainline. Drop it.

When building a multiplatform kernel, we could end up with a smaller
number of GPIOs than the one required by the platform the kernel was
running on.
Sort the max GPIO number by descending order so that we always take the
highest number required.

The timekeeping doesn't depend on HZ value in presence of fine grained
clocksource and hence there should not be any time drift because of HZ
value which was chosen to be divisor of 32768.
OMAP has been using HZ = 128 value to avoid any time drift issues
because of 32768 HZ clock. But with various measurements performed
with HZ = 100, no time drift is observed and it also proves the
point about HZ not having impact on time keeping on OMAP.
Very informative thread on this topic is here:

Alignment order for a dma iommu buffer is set by buffer size. For
large buffer, it is a waste of iommu address space. So configurable
parameter to limit maximum alignment order can reduce the waste.

Further, we now have a separate platform for virtual machines and qemu

Add support for the smallest, dumbest possible platform, to be

It only mandates a GIC and architected timers. Fits nicely with

git://git.kernel.org/pub/scm/linux/kernel/git/will/linux into next/virt
From Will Deacon:
This set of changes moves the arch-timer driver out from arch/arm/ and
into drivers/clocksource and unifies the new driver with the arm64 copy.
* 'for-arm-soc/arch-timers' of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux:
ARM: arch_timers: switch to physical timers if HYP mode is available
Documentation: Add ARMv8 to arch_timer devicetree
arm64: move from arm_generic to arm_arch_timer
arm64: arm_generic: prevent reading stale time
arm: arch_timer: move core to drivers/clocksource
arm: arch_timer: add arch_counter_set_user_access

The core functionality of the arch_timer driver is not directly tied to
anything under arch/arm, and can be split out.
This patch factors out the core of the arch_timer driver, so it can be
shared with other architectures. A couple of functions are added so
that architecture-specific code can interact with the driver without
needing to touch its internals.
The ARM_ARCH_TIMER config variable is moved out to
drivers/clocksource/Kconfig, existing uses in arch/arm are replaced with
HAVE_ARM_ARCH_TIMER, which selects it.

Implement timer_broadcast for the arm architecture, allowing for the use
of clock_event_device_drivers decoupled from the timer tick broadcast
mechanism.
