I2C chips can support a register offset, with registers accessible by
sending this offset as the first part of any read or write transaction.
Most I2C chips have a single byte offset, thus the offset length is 1.
This provides access for up 256 registers.
However other offset lengths are supported, including 0.
Add a command to provide access to the offset length from the command
line. This allows the offset length to be read or written.

We have flipped CONFIG_SPL_DISABLE_OF_CONTROL. We have cleansing
devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear
away the ugly logic in include/fdtdec.h:
#ifdef CONFIG_OF_CONTROL
# if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL)
# define OF_CONTROL 0
# else
# define OF_CONTROL 1
# endif
#else
# define OF_CONTROL 0
#endif
Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute. It refers to
CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for
SPL.
Also, we no longer have to cancel CONFIG_OF_CONTROL in
include/config_uncmd_spl.h and scripts/Makefile.spl.

Add option to set shell prompt string from menuconfig and migrate
boards globally.
The migration is done as follows:
- Boards that explicitly and unconditionally set CONFIG_SYS_PROMPT had the
entry moved to their defconfig files.
- Boards that defined some kind of #ifdef logic which selects the
CONFIG_SYS_PROMPT (for example qemu-mips) got an #undef CONFIG_SYS_PROMPT
right before the #ifdef logic and were left alone.
- This change forces CONFIG_SYS_PROMPT to be a per board decision, and thus
CONFIG_SYS_PROMPT was removed from all <soc>_common.h and <arch>_common.h
files. This results in a streamlined default value across platforms, and
includes the following files: spear-common, sunxi-common, mv-common,
ti_armv7_common, tegra-common, at91-sama5_common, and zynq-common.
- Boards that relied on <arch/soc>_common.h values of CONFIG_SYS_PROMPT were
not updated in their respective defconfig files under the assumption that
since they did not explicitly define a value, they're fine with whatever
the default is.
- On the other hand, boards that relied on a value defined in some
<boards>_common.h file such as woodburn_common, rpi-common,
bur_am335x_common, ls2085a_common, siemens_am33x_common, and
omap3_evm_common, had their values moved to the respective defconfig files.
- The define V_PROMPT was removed, since it is not used anywhere except for
assigning a value for CONFIG_SYS_PROMPT.

The code in question polls an USB port status via USB_REQ_GET_STATUS
to determine whether there is a device on the port or not. The way to
figure that out is to check two bits. Those are wPortChange[0] and
wPortStatus[0].
The wPortChange[0] indicates whether some kind of a connection status
change happened on a port (a device was plugged or unplugged). The
wPortStatus[0] bit indicates the status of the connection (plugged or
unplugged).
The current code tests whether wPortChange[0] == wPortStatus[0] and
if that's the case, considers the loop polling for the presence of a
USB device on port finished.
This works for most USB sticks, since they come up really quickly and
trigger the USB port change detection before the first iteration of the
detection loop happens. Thus, both wPortChange[0] and wPortStatus[0]
are set to 1 and thus equal. The loop is existed in it's first iteration
and the stick is detected correctly.
The problem is with some obscure USB sticks, which take some time before
they pop up on the bus after the port was enabled. In this case, both
the wPortChange[0] and wPortStatus[0] are 0. They are equal again, so
the loop again exits in the first iteration, but this is incorrect, as
such USB stick didn't have the opportunity to get detected on the bus.
Rework the code such, that it checks for wPortChange[0] first to test
if any connection change happened at all. If no change occured, keep
polling. If a change did occur, test the wPortStatus[0] to see there is
some device present on the port and only if this is the case, break out
of the polling loop.
This patch also trims down the duration of the polling loop from 10s
per port to 1s per port. This is still annoyingly long, but there is
no better option in case of U-Boot unfortunatelly. This change will
most likely increase the duration of 'usb start' on some platforms,
but this is needed to fix a bug.

The sysboot and pxe commands currently support either U-Boot formats or
raw zImages. Add support for the AArch64 Linux port's native image format
too.
As with zImage support, there is no auto-detection of the native image
format. Rather, if the image is auto-detected as a U-Boot format, U-Boot
will try to interpret it as such. Otherwise, U-Boot will fall back to a
raw/native image format, if one is enabled.
My belief is that CONFIG_CMD_BOOTZ won't ever be enabled for any AArch64
port, hence there's never a need to differentiate between CONFIG_CMD_
_BOOTI and _BOOTZ at run-time; compile-time will do. Even if this isn't
true, we want to prefer _BOOTI over _BOOTZ when defined, since _BOOTI is
definitely the native format for AArch64.
