The ClearFog Base boot from UART when setting the DIP switches to 01001.
Unfortunately, the SPL code sometimes fails to detect the UART boot
method at run-time. Add an alternative SAR UART boot value to fix this.
Note that this alternative value is not documented (Armada 38x Hardware
Specifications, Table 48). But experimentations showed it on the
ClearFog Base.

of the gd pointer.

The SPL code already knows which boot device it calls the spl_boot_mode()
on, so pass that information into the function. This allows the code of
spl_boot_mode() avoid invoking spl_boot_device() again, but it also lets
board_boot_order() correctly alter the behavior of the boot process.
The later one is important, since in certain cases, it is desired that
spl_boot_device() return value be overriden using board_boot_order().

This patch adds basic support for the Armada 375. Please note that
currently the SerDes and DDR3 init code for the A375 is not
included / enabled. This will be done in a later, follow-up patch.
Right now, this A375 mainline U-Boot can only be used by chainloading
it via the original Marvell U-Boot. This can be done via this
command:
=> tftpboot 00800000 a375/u-boot-dtb.bin;go 00800000

This patch adds runtime detection of the Marvell UART boot-mode (xmodem
protocol). If this boot-mode is detected, SPL will return to the
BootROM to continue the UART booting.
With this patch its now possible, to generate a U-Boot image that
can be booted either from the strapped boot-device (e.g. SPI NOR, MMC,
etc) or via the xmodem protocol from the UART. In the UART case,
the kwboot tool will dynamically insert the UART boot-device type
into the image. And also patch the load address in the header, so
that the mkimage header will be skipped (as its not expected by the
Marvell BootROM).
This simplifies the development for Armada XP / 38x based boards.
As no special images need to be generated by selecting the
MVEBU_BOOTROM_UARTBOOT Kconfig option.
Since the Kconfig option MVEBU_BOOTROM_UARTBOOT is not needed any
more, its now completely removed.

This patch removes the call to arch_cpu_init() in the SPL U-Boot version.
As SPL does not need all the configuration done in this function. And
also does not need the reconfiguration of the internal register
address to 0xf1000000. This will be done by the main U-Boot later on.
This also fixes a problem with the timer not beeing initialized on AXP,
as needed for the mdelay in the setup_usb_phys(). This will now only
be called once in main U-Boot.

This patch adds full DM support to the SPL on MVEBU. Currently
only serial is supported. Other drivers will follow.
This patch also adds the necessary config values for the DEBUG UART
to the MVEBU defconfig files. This came in handy while implementing
this DM support.
Additionally, the mvebu specific SPL linker script is removed and
this common one is used instead:
arch/arm/cpu/u-boot-spl.lds
This common linker script already handles all special cases. No need
to reinvent the wheel for MVEBU here.

This patch adds driver model support for some Marvell MVEBU SoC's. Including
Armada XP and 38x. All 3 currently mainlined boards are converted. DM is now
selected automatically for MVEBU platforms.
With this DM support now available for MVEBU, hardcoding the base addresses
and other information is not necessary any more. Probing should be done
by using the values provided via the device tree now instead. For this
the driver also need to be converted to DM. Patches for some of the drivers
will follow.

Instead of calling board_init_r() directly from board_init_f(), just
return from board_init_f(). This will make the code continue executing
in crt0.S _main(), from which the board_init_r() is called. This patch
aligns the MVEBU SPL with the correct SPL design as well as reduces
the stack utilisation slightly.

This patch enables the use of the kwboot tool, to boot mainline U-Boot
on the Marvell Armada XP/38x SoC's. This is done by returning to the
SoC's BootROM after SPL has initialized the SDRAM. We need to make sure
to not reconfigure the internal register space and MBARs. Otherwise
the BootROM will not be able to continue after SPL jumps back to it.
To use this feature, please don't forget to change the BOOT_FROM line
in your board specfic kwbimage.cfg file this way:
BOOT_FROM uart
