Adding userspace support for the MC (Management Complex) means exporting
an ioctl capable device file representing the root resource container.This new functionality in the fsl-mc bus driver intends to provide
userspace applications an interface to interact with the MC firmware.Commands that are composed in userspace are sent to the MC firmware
through the FSL_MC_SEND_MC_COMMAND ioctl. By default the implicit MC
I/O portal is used for this operation, but if the implicit one is busy,
a dynamic portal is allocated and then freed upon execution.Signed-off-by: Ioana Ciornei

if there's no sysstatus srst_shift to fix a bogus resetdone warning on

Commit d46f9fbec719 ("bus: ti-sysc: Use optional clocks on for enable and
wait for softreset bit") started showing a "OCP softreset timed out"
warning on enable if the interconnect target module is not out of reset.
This caused the warning to be often triggered for i2c and hdq while the
devices are working properly.Turns out that some interconnect target modules seem to have an unusable
reset status bits unless the module specific reset quirks are activated.Let's just skip the reset status check for those modules as we only want
to activate the reset quirks when doing a reset, and not on enable. This
way we don't see the bogus "OCP softreset timed out" warnings during boot.Fixes: d46f9fbec719 ("bus: ti-sysc: Use optional clocks on for enable and wait for softreset bit")

There are several occurrences of the following pattern:
for_each_memblock(memory, reg) {
start = __pfn_to_phys(memblock_region_memory_base_pfn(reg);
end = __pfn_to_phys(memblock_region_memory_end_pfn(reg));/* do something with start and end */
}Using for_each_mem_range() iterator is more appropriate in such cases and
allows simpler and cleaner code.[akpm@linux-foundation.org: fix arch/arm/mm/pmsa-v7.c build]

Currently the DPRC scan function is used only by the bus driver.
But the same functionality will be needed by the VFIO driver.
To support this, the dprc scan function was exported and a little
bit adjusted to fit both scenarios. Also the scan mutex initialization
is done when the bus object is created, not in dprc_probe in order
to be used by both VFIO and bus driver.
Similarily dprc_remove_devices is exported to be used by VFIO.Reviewed-by: Laurentiu Tudor
