19710a8b47 Remove pd_prot and pd_cache members from struct arm_devmap_entry.
The struct is used for definition of static device mappings which
should always have same protection and attributes.

3245bc3a66 Add support for the Allwinner i2c device. This is similar to the existing
Marvell twsi part, however uses different register locations, as such split
the existing driver into Marvell and Allwinner attachments.

While here clean a few style issues.

31bb8ee5bd Convert rman to use rman_res_t instead of u_long
Summary:
Migrate to using the semi-opaque type rman_res_t to specify rman resources.  For
now, this is still compatible with u_long.

This is step one in migrating rman to use uintmax_t for resources instead of
u_long.

Going forward, this could feasibly be used to specify architecture-specific
definitions of resource ranges, rather than baking a specific integer type into
the API.

This change has been broken out to facilitate MFC'ing drivers back to 10 without
breaking ABI.

fb8428bdbe Introduce initial driver for PMSU on Armada38x
This is a stub for PMSU driver. Note that it cannot be used to set the
secondary core boot address during attach because drivers are attached
later than SI_SUB_CPU sysinit where cores are started.
Setting the boot address should be done manually in platform_mp_start_ap().

SMP is working fine with this commit and was enabled in Armada38x kernel
configuration file.

522b95ca9c Fix a strange macro re-definition compile error. If the VM_MAXUSER_ADDRESS
value is defined as a config option the definition is emitted into
opt_global.h which is force-included into everything.  In addition, the
symbol is emitted by the genassym mechanism, but that by its nature reduces
the value to a 0xnnnnnnnn number.  When compiling a .S file you end up
with two different definitions of the macro (they evaluate to the same
number, but the text is different, upsetting the compiler).

Nothing has changed about this code for a while but the compile error is
new, so this must be fallout from the clang 3.7 update or something.

c71425db1d An IPI must be cleared before it is handled otherwise next IPI could be
missed. In other words, if a new request for an IPI is sent while the
previous request is being handled but the IPI is not cleared yet, the
clearing of the previous IPI request also clears the new one and the
handling is missed.

There are only three MP interrupt controllers in ARM now. Two of them are
fixed by this change, the third one is correct, probably only just by
accident. The fix is minimalistic as new interrupt framework is awaited.

It was debugged on RPi2 where missing IPI handling together with SCHED_ULE
led to situation in which tdq_ipipending was not cleared and so IPI_PREEMPT
was stopped to be sent. Various odditys were found related to slow system
response time like various events timed out, and slow console response.
