USB devices are not really designed to get the power bounced off and on
at them. Esp. USB powered harddisks do not like this.
Currently we power off the USB ports both on a "usb reset" and when
booting the kernel, causing the usb-power to bounce off and then back
on again.
This patch removes the powering off calls, fixing the undesirable power
bouncing.
Note this requires some special handling for the OTG port:
1) We must skip the external vbus check if we've already enabled our own
vbus to avoid false positives
2) If on an usb reset we no longer detect that the id-pin is grounded, turn
off vbus as that means an external vbus may be present now

Spring is the first ARM-based HP Chromebook 11. It is similar to snow
and it uses the same Samsung Exynos5250 chip. But has some unusual

U-Boot). Now that the exynos5 code is common we can support spring just
by adding a device tree and a few lines of configuration.

While generating the page tables, a running integer index is shifted by
SECTION_SHIFT (29) and causes overflow for any integer bigger than 7.
The page tables therefore alias to the same 8 sections and cause U-Boot
to hang once the MMU is enabled.
Fix this by making the index a 64-bit unsigned integer and so avoid the
overflow.

Because the top-level Makefile forces all the source files
to include include/linux/kconfig.h (see the UBOOTINCLUDE define),
these includes are redundant.
By the way, there are exceptions for the statement above; host

board configuration, although I think they should not. So, some

OMAP devices might boot from peripheral devices, such as UART or USB.
When that happens, the U-Boot SPL tries to boot the next stage (complete U-Boot)
from that peripheral device, but in most cases, this is not a valid boot device.
This introduces a fallback option that reads the SYS_BOOT pins, that are used by
the bootrom to determine which device to boot from. It is intended for the
SYS_BOOT value to be interpreted in the memory-preferred scheme, so that the
U-Boot SPL can load the next stage from a valid location.
Practically, this options allows loading the U-Boot SPL through USB and have it
load the next stage according to the memory device selected by SYS_BOOT instead
of stalling.

This introduces OMAP3 support for the common omap boot code, as well as a
major cleanup of the common omap boot code.
First, the omap_boot_parameters structure becomes platform-specific, since its
definition differs a bit across omap platforms. The offsets are removed as well
since it is U-Boot's coding style to use structures for mapping such kind of
data (in the sense that it is similar to registers). It is correct to assume
that romcode structure encoding is the same as U-Boot, given the description
of these structures in the TRMs.
The original address provided by the bootrom is passed to the U-Boot binary
instead of a duplicate of the structure stored in global data. This allows to
have only the relevant (boot device and mode) information stored in global data.
It is also expected that the address where the bootrom stores that information
is not overridden by the U-Boot SPL or U-Boot.
The save_omap_boot_params is expected to handle all special cases where the data
provided by the bootrom cannot be used as-is, so that spl_boot_device and
spl_boot_mode only return the data from global data.
All of this is only relevant when the U-Boot SPL is used. In cases it is not,
save_boot_params should fallback to its weak (or board-specific) definition.
save_omap_boot_params should not be called in that context either.
