fecf84c14f ARM: mach-shmobile: kzm9g: enable SMP boot
Update the KZM9G defconfig and the code in platsmp.c to support SMP on
the sh73a0 based KZM9G board. Also fix up the earlyprintk setting that
was previously incorrect.

173bf69a7a ARM / mach-shmobile: Use preset_lpj with calibrate_delay()
Update the mach-shmobile shared delay calibration code for late
timers. All existing in-tree non-DT socs are however using early
timers today and they are unaffected by this change.

The patch modifies shmobile_setup_delay() from using lpj_fine
to preset_lpj. This change allows us to preset the worst case
loops-per-jiffy value to all CPU cores on the system.

The old code which made use of lpj_fine did not affect the
secondary CPU cores which made it impossible to boot on SMP
without early timers.

Needed for SMP SoCs using late timers like EMEV2 or any other
mach-shmobile SMP SoC that makes use of late timers via DT.

Fix SMP TWD boot regression on sh73a0 based platforms caused by:

4200b16 ARM: shmobile: convert to twd_local_timer_register() interface

After the merge of the above commit it has been impossible to boot
sh73a0 based SoCs with SMP enabled and CONFIG_HAVE_ARM_TWD=y. The
kernel crashes at smp_init_cpus() timing which is before the console
has been initialized, so to the user this looks like a kernel lock up
without any particular error message.

This patch fixes the regression on sh73a0 by moving the TWD
registration code from smp_init_cpus() to sys_timer->init() time.

This patch removed shmobile_twd_init() which is no longer needed

Add generic DT board support for the sh7372 SoC V2.

SCIF serial ports and timers are kept as regular
platform devices. Other on-chip and on-board devices
should be configured via the device tree.

Tested on the mackerel board via kexec using a zImage
kernel with an appended dtb.

At this point there is no interrupt controller support
in place but such code will be added over time when
proper IRQ domain support has been added to INTC.

012f825f13 ARM: mach-shmobile: Rework sh7372 INTCS demuxer V2
This patch is the sh7372 INTC demux rework V2.

Updates the sh7372 INTCS demuxer to not hook into
the INTCA interrupt controller. The mask register
for the chained INTCS interrupt source happens
to be located in the INTCS register range instead of
the INTCA as expected. To allow each INTCA and INTCS
interrupt controller to work in their own IRQ range
this patch moves the INTCS vector away.

Needed for future IRQ domain support.

2ff6530c06 ARM: mach-shmobile: Use INTC_IRQ_PINS_16H on sh7372
Use INTC_IRQ_PINS_16H on sh7372 to have two separate
interrupt controllers for the external IRQ pins.

This is preparation work for future IRQ domain support.

1ee8299a9e ARM: mach-shmobile: Use 0x3400 as INTCS vector offset
Update mach-shmobile to use 0x3400 as INTCS_VECT_BASE.

Since the ARM architecture a little while back added support
for 10 bit irqs we can now undo the previously merged commit
9b7c23adb350a108737a993c9c781463c1439dc6 and use 0x3400 as
INTCS vector base.

This change is necessary to avoid overlapping of interrupt
ranges so separate IRQ domains can be used for different INTC
instances. Without this fix the vectors used by various INTC
instances are overlapping on for instance sh7372 which works
at the moment but breaks upcoming IRQ domain support.

d7e7e4ffc6 ARM: mach-shmobile: Introduce INTC_IRQ_PINS_16H
Add INTC_IRQ_PINS_16H to allow broken out support of the
the high 16 external interrupt pins. On SoCs with 32 external
interrupt pins the interrupt vectors for the low 16 and the
high 16 interrupt pins are sparesly populated. The low 16 are
at 0x0200 and high 16 are at 0x3200 which with current macros
results in a separation of 384 linux interrupts. This sparse
population makes it unsuitable with a single IRQ domain to
cover the full IRQ range, so this macro breaks out the 32 pins
into two separate 16 bit controllers to allow two independent
INTC instances with two separate IRQ domains.

0f2c9f20e4 ARM: mach-shmobile: Introduce shmobile_setup_delay()
Add the function shmobile_setup_delay() to let platforms
configure their maximum loops per jiffy delay. With this
jiffies calculation done the dependency on early timer
is removed.

In the future this allows us to assign timers
using the regular driver model via the device tree.
