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.

Armada 385 contains 64 lines of HD eFuse and 2 lines of LD eFuse. HD eFuse
is used for secure boot and each line is 64 bits long + 1 lock bit. LD
eFuse lines are 256 bits long + 1 lock bit. LD 0 line is reserved for
Marvell Internal Use and LD 1 line is for General Purpose Data. U-Boot
already contains HD eFuse reading and programming support.
This patch implements LD eFuse reading support. LD 0 line is mapped to
U-Boot fuse bank 64 and LD 1 line to fuse bank 65.
LD 0 Marvell Internal Use line seems that was burned in factory with some
data and can be read by U-Boot fuse command:
=> fuse read 64 0 9
LD 1 General Purpose Data line is by default empty and can be read by
U-Boot fuse command:
=> fuse read 65 0 9

Do not call pci_set_region() for resources which were not properly mapped.
This prevents U-Boot to access unmapped memory space.
Update MBUS_PCI_MEM_SIZE and MBUS_PCI_IO_SIZE macros to cover all PCIe MEM
and IO ranges. Previously these macros covered only address ranges for the
first PCIe port. Between MBUS_PCI_IO_BASE and MBUS_PCI_MEM_BASE there is
space for six 128 MB long address ranges. So set MBUS_PCI_MEM_SIZE to value
of 6*128 MB. Similarly set MBUS_PCI_IO_SIZE to 6*64 KB.
Function resource_size() returns zero when start address is 0 and end
address is -1. So set invalid resources to these values to indicate that
resource has no mapping.
Split global PCIe MEM and IO resources (defined by MBUS_PCI_*_* macros)
into PCIe ports in mvebu_pcie_bind() function which allocates per-port
based struct mvebu_pcie, instead of using global state variables
mvebu_pcie_membase and mvebu_pcie_iobase. This makes pci_mvebu.c driver
independent of global static variables (which store the state of
allocation) and allows to bind and unbind the driver more times.

Currently on Armada-37xx the mem_map structure is statically defined to
map first 2 GB of memory as RAM region, and system registers and PCIe
region device region.
This is insufficient for when there is more RAM or when for example the
PCIe windows is mapped to another address by the CPU Address Decoder.
In the case when the board has 4 GB RAM, on some boards the ARM Trusted
Firmware can move the PCIe window to another address, in order to
maximize possible usable RAM.
Also the dram_init and dram_init_banksize looks for information in
device-tree, and therefore different device trees are needed for boards
with different RAM sizes.
Therefore we add code that looks at how the ARM Trusted Firmware has
configured the CPU Address Decoder windows, and then we update the
mem_map structure and compute gd->ram_size and gd->bd->bi_dram bank
base addresses and sizes accordingly.

which are unable to map all PCIe ports, e.g. the Armada-XP theadorable:

boot. The first is when the normal boot media is blank (or otherwise
missing the kwb header). The second is when the boot sequence has been
interrupted with the magic byte sequence on the UART lines.
In the first mode the bootROM routine and error code register will
indicate that there was an error booting from the configured media in
bits 7:0. In the second mode there is no error to indicate but the boot
source is provided via bits 31:28.
Handle both situations so that kwboot can be used for both boot

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
