mbus driver is initialized from arch_cpu_init() callback which is called
before relocation. This driver stores lot of functions and structure
pointers into global variables, so it is data position dependent.
Therefore after relocations all pointers are invalid and driver does not
work anymore as all pointers referes to the old memory, which overlaps with
CONFIG_SYS_LOAD_ADDR and ${loadaddr}.
For example U-Boot fuse command crashes if loadaddr memory is cleared or
rewritten by some image loaded by U-Boot load command.
mw.w ${loadaddr} 0x0 10000
fuse read 0 1 2
Fix this issue by removing of all mbus global variables in which are stored
pointers to structures or functions which changes during relocation. And
replace it by direct function calls (not via pointers). With this change
fuse command finally works.

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

This patch enables the PCIe port specific link capabilities configuration
for Armada XP. The weak function board_sat_r_get() was used to return
a common flag for PCIe Gen1 vs Gen2 capability for all PCIe ports. This
is now changed with this patch to return a bit per PCIe port (4 bits
in this case, bit 0 for PCIe port 0, etc).
The theadorable board uses this new feature to configure PCIe port 0
as Gen1 and all other PCIe ports as Gen2 capable. All other AXP boards
using this function are not changed in the configuration and still
configure all ports as PCIe Gen2.
This patch also removes the parameter "pex_mode" from
board_serdes_cfg_get() as this parameter was not used in any of the
implementations.

Move the gdsys Controlcenter DC specific build time kwbimage.cfg
generation code into the mach-mvebu/ directory to be shared by all 32bit
mvebu platforms.
Remove board specific kwbimage.cfg files, and use the generated one
instead. These files are all identical, with two exceptions. Clearfog
and Helios4 use the sdio boot device, whereas all others use spi. Update
the defconfigs for the exceptional boards to generate the same
kwbimage.cfg as before.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

Update this driver to support driver model. As all MVEBU boards using
this driver are converted with this patch, the non-driver-model code
can be removed completely. This is also the reason why this patch
is quite big and includes a) the driver change and b) the
platform change. As its not git-bisect save otherwise.
With this conversion, some parameters are now extracted from the
DT instread of using the config header defines. The supported
properties right now are:
PHY-mode ("phy-mode") and PHY-address ("reg").
The base addresses for the ethernet controllers can be removed from
the header files as well.
Please note that this patch also removes the E1000 network driver
from some MVEBU config headers. This is necessary, as with DM_ETH
configured and the e1000 driver enabled, the PCI driver also needs
to support DM. But the MVEBU PCI(e) driver still needs to get
ported to DM. When this is done, the E1000 driver can be enabled
again.

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 file should contain the bin_hdr generated by the original Marvell
U-Boot implementation. As this is currently not included in this
U-Boot version, we have added this placeholder, so that the U-Boot
image can be generated without errors.
If you have a known to be working bin_hdr for your board, then you
just need to replace this text file here with the binary header
and recompile U-Boot.
In a few weeks, mainline U-Boot will get support to generate the
bin_hdr with the DDR training code itself. By implementing this code
as SPL U-Boot. Then this file will not be needed any more and will
get removed.
