Instead of requiring the users to hardcode MERAM allocation in platform
data, allocate blocks at runtime using genalloc.

The MERAM resource currently combines both the registers space and the
MERAM space. Only the register space needs to be ioremapped, split the
resource to make that possible.

The struct sh_mobile_lcdc_chan_cfg platform data contains a list of
video modes. Name the lcd_cfg and num_cfg fields to reflect that they

Now when all SoCs and boards are converted to use
shmobile_earlytimer_init(), change the default behavior
of shmobile_timer.init() from using early timer to
do nothing which is suitable for upcoming DT support.

Move the SoC specific timer code from Marzen board code

All callers (board-mityomapl138.c and board-da850-evm.c) use it in
__init functions only.
This fixes:
WARNING: vmlinux.o(.text+0xd664): Section mismatch in reference from the function da850_register_pm() to the function .init.text:da8xx_get_mem_ctlr()
The function da850_register_pm() references
the function __init da8xx_get_mem_ctlr().
This is often because da850_register_pm lacks a __init
annotation or the annotation of da8xx_get_mem_ctlr is wrong.

Stepan found:
CPU0 CPUn
_cpu_up()
__cpu_up()
boostrap()
notify_cpu_starting()
set_cpu_online()
while (!cpu_active())
cpu_relax()
<PREEMPT-out>
smp_call_function(.wait=1)
/* we find cpu_online() is true */
arch_send_call_function_ipi_mask()
/* wait-forever-more */
<PREEMPT-in>
local_irq_enable()
cpu_notify(CPU_ONLINE)
sched_cpu_active()
set_cpu_active()
Now the purpose of cpu_active is mostly with bringing down a cpu, where
we mark it !active to avoid the load-balancer from moving tasks to it
while we tear down the cpu. This is required because we only update the
sched_domain tree after we brought the cpu-down. And this is needed so
that some tasks can still run while we bring it down, we just don't want
new tasks to appear.
On cpu-up however the sched_domain tree doesn't yet include the new cpu,
so its invisible to the load-balancer, regardless of the active state.
So instead of setting the active state after we boot the new cpu (and
consequently having to wait for it before enabling interrupts) set the
cpu active before we set it online and avoid the whole mess.

This was inspired by mchehab@redhat.com's observation that we
didn't have EDAC configured on by default in both files. In addition,
we were setting INITRAMFS_SOURCE to a non-empty string, which isn't
a very common default and required editing to do test builds.
