ARM: at91: add sama5d27-based Groboards Giant Board support ...

The Groboards Giant Board is a ATSAMA5D27C-D1G SiP-based SBC.
The board features a 500MHz ARM Cortex-A5 and 128MB DDR2 SDRAM in the
SiP as well as a MicroSD slot on the PCB.

barebox doesn't yet support the sama5d2 SDHCI-variant, so board support
is limited to toggling the LED and interfacing with the UART, but add
this now till the rest may follow. Device tree is based on the vendor's
device-tree available at https://github.com/Groboards/giantboard-tools

ARM: at91: sama5d27-som1: branch to noinline function after stack setup ...

We need to branch out as soon as possible after setting up the stack.
Do this and thereby avoid an access violation we now run into using
OSELAS.Toolchain-2019.09.1.

ARM: at91: sama5d27-som1: clean up lowlevel.c ...

In ARM, stack decrements before storing values, so decrementing a number
from the stack base is unnecessary. Existing instances of this were
removed in 6b3dc4abd8 ("ARM: Cleanup stack offset cargo cult"), but the
sama5d27-som1 board was added later than that. Fix the cargo cult here
as well and while at it, turn a macro that doesn't need to be one
into a static inline function.

usb: Add extra delay for device scan ...

Since b1d9837182, detection of various USB flash drives stopped working.
While the changes itself look correct, probably the HUB requires some
"recovery time" between the GET_STATUS commands in order to be able to
detect devices.

Our configuration: i.MX6ULL (USB-OTG) with only one port on the root
HUB. This port is connected to a Microchip USB4916 hub (permanently
attached). The USB4916 is configured with it's power on defaults which
means that bPwrOn2PwrGood is set to the maximum (0xFF = 510 ms).

ARM: dts: phycore-imx6: change mtd-partition names for compatibility with kernel ...

The NVMEM-subsystem in newer kernels does not allow identical partition
names on different subdevices. According to the recommendation, we have to
rename the partition names to be compatible with actual kernel
versions.

To minimize the problems which could possibly arise, the nand device is
not changed. For all other devices, we prepend the device name to the
partitions.
