usb: dwc2-otg: make regs_otg (in platdata) a uintptr_t
The regs_otg field in uintptr_t of the platform data structure for
dwc2-otg has thus far been an unsigned int, but will eventually be
casted into a void*.
This raises the following error with GCC 6.3 and buildman:
../drivers/usb/gadget/dwc2_udc_otg.c: In function 'dwc2_udc_probe':

rockchip: efuse: add (misc) driver for RK3399 non-secure efuse block
This adds a simple driver for reading the efuse block of the RK3399.
It should be easy enough to add drivers for other devices (e.g. the
RK3328, RK3368, etc.) by passing the device details via driver_data.
Unlike the kernel driver (using the nvmem subsystem), we don't expose
the efuse as multiple named cells, but rather as a linear memory that
can be read using misc_read(...).
The primary use case (as of today) is the generation of a 'serial#'
(and a 'cpuid#') environment variable for the RK3399-Q7 (Puma)
system-on-module.
Note that this adds a debug-only (i.e. only if DEBUG is defined)
command 'rk3399_dump_efuses' that dumps the efuse block's content.
N.B.: The name 'rk3399_dump_efuses' was intentionally chosen to
include a SoC-name (together with a comment in the function) to
remind whoever adds support for additional SoCs that this
function currently makes assumptions regarding the size of the
fuse-box based on the RK3399. The hope is that the function is

bootstage: Fix up code style and comments
There are several code style and comment nits. Fix them and also remove
the comment about passing bootstage to the kernel being TBD. This is
already supported.

bootstage: Convert to use malloc()
At present bootstage uses the data section of the image to store its
information. There are a few problems with this:
- It does not work on all boards (e.g. those which run from flash before
relocation)
- Allocated strings still point back to the pre-relocation data after
relocation
Now that U-Boot has a pre-relocation malloc() we can use this instead,
with a pointer to the data in global_data. Update bootstage to do this and
set up an init routine to allocate the memory.
Now that we have a real init function, we can drop the fake 'reset' record
and add a normal one instead.
Note that part of the problem with allocated strings remains. They are
reallocated but this will only work where pre-relocation memory is
accessible after relocation.

bootstage: Require timer_get_boot_us() to be defined
At present we provide a default version of this function for use by
bootstage. However it uses the system timer and therefore likely requires
driver model. This makes it impossible to time driver-model init.
Drop the function and require boards to provide their own. Add a sandbox
version also. There is a default implememtation in lib/time.c for boards
which use CONFIG_SYS_TIMER_COUNTER.

cmd/elf.c: Support passing arguments with bootelf
The bootelf command could, but does not, pass additional arguments along
on the command line. Make do_bootelf consume bootelf/flags/address as
needed and then pass along anything else to the ELF application we've
launched.

reset: sti: add deassert counter in reset channel descriptor
This deassert counter allow to manage "shared" reset lines
encountered in some specific case. On STiH410 SoC, DWC3,
EHCI and OHCI are all using a respective PHY, but all of
these PHYs shared a "global" reset.
Currently, during command "usb stop", all host controller are
stopped (XHCI, EHCI and OHCI). XHCI is first shutdowned, which
means that PHY global reset is asserted. Then EHCI is shutdowned,
but its PHY reset has already been asserted which make handshake()
call failed in ehci_shutdown().
This counter allows to really assert a reset lines only when the
"last" user is asserting it.

common: arm: davinci: Move header file out of common
We should not have an arch-specific header file in common.h. Instead, use
the asm/hardware.h header to provide the required declarations, and drop
the common.h changes.
