4f29862487 Peach-Pi: Use the enhanced usb_copy() prototype
Exynos5800 IROM has a different, from 5250 and 5420, prototype of the
usb_copy() function. Luckily the earlier version did not expect any
arguments, which means the same code could be used with old and new
SoCs, the old ones just ignoring the arguments.

Add a 4G configuration and choose it based on the number of banks

061091098a DMC: Exynos5: Enable update mode for DREX controller
As per Exynos5800 UM ver 0.00 section 17.13.2.1
CONCONTROL register bit 3 [update_mode], Exynos5800 does not
support the PHY initiated update. And it is recommanded to
set this field to 1'b1 during initialization. This patch sets this bit.
Applying MC-initiated mode makes DDL tracking ON, that helps in
compensate MIF voltage variation.

aa14b42d53 Exynos5800: Introduce new proid for Exynos5800
This patch intends to add a new proid for Exynos5800 which is a
variant of Exynos5420. Product id for Exynos5800 is 0x5422.
Both Exynos5420 and Exynos5800 are pin to pin compitable. This
gives us an advantage of reusing Exynos5420 clock, pinmux, memory
and other settings.

f2863ff3f4 arm: imx: make bmode command work with SPL/U-Boot combo
The bmode command forces the SoC to use a specific boot device
by writing its boot mode into SRC_GPR9, and notifying the SoC of
the change using SRC_GPR10[28] bit: if the bit is on, bootROM
uses the value in SRC_GPR9 instead of SRC_SMBR1 to determine
the boot device.

SPL on the other hand is oblivious to this distinction, so once
the bootROM loads SPL from the device configured in SRC_GPR10,
SPL will attempt to load U-Boot from the device configured in
SRC_SMBR1, which is not updated by the bootROM to the value in
SRC_GPR9.

The result is that the selected boot device is not used across all
the boot stages.

Update spl_boot_device() to look at gpr9 when necessary.

When the board is kicked via a debbuger rather than pushing the
