e2140588dd usb: gadget: fastboot: terminate commands with NULL
Without NULL termination, various commands will read past the
end of input. In particular, this was noticed with error()
calls in cb_getvar and simple_strtoul() in cb_download.

Since the download callback happens elsewhere, the 4k buffer
should always be sufficient to handle command arguments.

16b61d13ba usb: musb-new: core: set MUSB_POWER_HSENAB in MUSB_POWER for host mode
This bit allows the MUSB controller to negotiate for high-speed mode when
the device is reset by the hub. If unset, Babble errors occur with
high-speed mass storage devices right after the first packet. This condition
is not caught by the interrupt handles in U-Boot, so no recovery is done,
and the USB communication is stuck.

To fix this, set the bit unconditionally, not only for
CONFIG_USB_GADGET_DUALSPEED but also for host-only modes.

5b7103e0af nitrogen6x: config: allow boot to USB stick
This patch enables boot to USB storage devices by expanding on the list
of boot devices.

Because the USB startup currently takes a long time, it places USB at
the end of the list of supported devices.

You can over-ride the boot order using the bootdevs environment variable.
For instance, this will make USB the first (highest priority) device:

	U-Boot > setenv bootdevs usb mmc sata
	U-Boot > saveenv

ce9507b793 nitrogen6x: display use I2C detect for HDMI
The HPD pin and RX_SENSE registers have proven to be less reliable
than using I2C on the EDID pins for detection of an HDMI monitor.
In particular, when the HDMI output is reset through a "reboot"
cycle, the detect_hdmi() routine often bounces, resulting in
a failure to detect a connected monitor.

to come.

This is necessary due to various features of the boards, which
unfortunatelly cannot be autodetected.

47f9b4e1f3 arm: socfpga: Clean up SoCFPGA configuration
Reorganize and cleanup the configuration file for SoCFPGA. There
is no functional change after this cleanup. This was necessary,
since the file was a wild mess and it was impossible to make sense
of it's content, let alone change something without breaking some
other thing. This patch puts the contents on par with regular U-Boot
standards.

Also remove unused preprocessor symbols CONFIG_SINGLE_BOOTOADER
and CONFIG_USE_IRQ, which is undefined by default. Finally, do
logical reordering of the defines in the file so it's much more
readable. The reordering was also necessary for the splitting
as the initial one was messy.

abb25f4e95 arm: socfpga: reset: Add function to reset FPGA bridges
Add function to enable and disable FPGA bridges. This code is used
by the FPGA manager to disable the bridges before programming the
FPGA and will later be also used by the initialization code for the
chip to put the chip into well defined state during startup.
