a0d10caff7 EHCI: Make core reset and port speed reading more generic.
Use driver settable callbacks for handling of:
- core post reset
- reading actual port speed

Typically, OTG enabled EHCI cores wants setting of USBMODE register,
but this register is not defined in EHCI specification and different
cores can have it on different offset.

Also, for cores with TT extension, actual port speed must be determinable.
But again, EHCI specification not covers this so this patch provides
function for two most common variant of speed bits layout.

fd752ed774 SMP support for ARMv6/v7 HW watchpoints
Use per-CPU structure to store HW watchpoints registers state
for each CPU present in the system. Those registers will be restored
upon wake up from the STOP state if requested by the debug_monitor
code. The method is similar to the one introduced to AMD64.

We store all possible 16 registers for HW watchpoints
(maximum allowed by the architecture).
HW breakpoints are not maintained since they are used for single
stepping only.

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.

030d8a98be Introduce support for HW watchpoints and single stepping for ARMv6/v7
Allows for using hardware watchpoints for 1, 2, 4, 8 byte long addresses.
The default configuration of watchpoint is RW but code allows to select
RO or WO and X.
Since debugging registers are per-CPU (CP14) the watchpoint is set on
the CPU that was lucky (or not) to enter DDB.

HW breakpoints are used to perform single step in KDB.
When HW breakpoint is enabled all watchpoints are temporary disabled
to avoid recursive abort on both watchpoint and breakpoint.
In case of branch, the breakpoint is set to both - next instruction
and possible branch address. This requires at least 2 breakpoints
supported in the CPU however this is a must for ARMv6/v7 CPUs.

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
