The initialisation of the memory nodes on mvebu is a bit
compilcated:
pure_initcall(mvebu_memory_fixup_register)
of_register_fixup(mvebu_memory_of_fixup, NULL)
core_initcall(kirkwood_init_soc)
mvebu_set_memory()
core_initcall(of_arm_init)
of_fix_tree()
mvebu_memory_of_fixup()
First a mvebu common of_fixup function is registered, then the SoC
calls mvebu_set_memory which stores the memory base and size in global
variables. Afterwards the of_fixup is executed which fixes the memory
nodes according to the global variables.
Instead register a SoC specific fixup which directly calls mvebu_set_memory
with the memory base and size as arguments:
pure_initcall(kirkwood_register_soc_fixup);
of_register_fixup(kirkwood_init_soc, NULL);
core_initcall(of_arm_init)
of_fix_tree()
kirkwood_init_soc()
mvebu_set_memory(phys_base, phys_size);

Multi-SoC support for MVEBU will add mbus ranges for all compiled
SoCs. To protect the mbus node of the SoC barebox is executed on
from others ranges, pass machine's compatible to mvebu_mbus_add_range
and check before applying the fixup.

mvebu has a reset_cpu function per SoC this does not work when multiple
SoCs are selected, so add a common reset_cpu function which calls into
the SoC specific ones.

On Marvell MVEBU SoCs memory size is set up by BootROM and can be read
from SoC's RAM controller. With early DT fixups available, set corresponding
DT node to reflect accessible amount of directly attached RAM.
This patch also removes non-DT call to arm_add_mem_device to silence a
warning about request_region conflict due to adding a mem device twice.

For each supported MVEBU SoC, add the corresponding remapped registers
to fix them up in provided DTBs.

With OF clock providers, we can now remove temporary clocks and clock
aliases. Also, non-DT device probing for timer and serial is removed.

Clocks need to be accessed early for DT support, so move soc_init to
core_initcall instead of postcore_initcall.

At early stage after boot, all MVEBU SoCs are similar enough to have
a common lowlevel and barebox entry. We also remap the internal register
base address to 0xf100000 as it gives some 512M more of contiguous address
space. As we cannot determine real memory size that early, we start with
a default memory size of 64M and probe correct size later in SoC init.

This commit adds minimal support for the Marvell Dove SoC (88AP510) as
first SoC of the Marvell Orion family. Orion SoCs have a different timer,
therefore current mach-mvebu and Armada 370/XP Kconfig and Makefiles are
slightly modified and a new clocksource drivers is added.
