4364071362 pci: pci_mvebu: Add support for Kirkwood PCIe controllers
Kirkwood uses macros KW_DEFADR_PCI_MEM and KW_DEFADR_PCI_IO for base
address of PCIe mappings. Size of PCIe windows is not defined in any macro
yet, so export them in new KW_DEFADR_PCI_MEM_SIZE and KW_DEFADR_PCI_IO_SIZE
macros.

Kirkwood arch code already maps mbus windows for io and mem, so avoid
calling mvebu_mbus_add_window_by_id() function which would try to do
duplicate window mapping.

Kirkwood PCIe controllers already use "marvell,kirkwood-pcie" DT compatible
string, so mark pci_mvebu.c driver as compatible for it.

35b65dd8ef reset: Remove addr parameter from reset_cpu()
Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to.  This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value.  Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.

Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g.  COLD vs WARM resets).  As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).

To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely.  Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.

This transformation was done with the following coccinelle patch:

    @@
    expression argvalue;
    @@
    - reset_cpu(argvalue)
    + reset_cpu()

    @@
    identifier argname;

    - reset_cpu(argtype argname)
    + reset_cpu(void)

b75d8dc564 treewide: convert bd_t to struct bd_info by coccinelle
The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:

  It's a **mistake** to use typedef for structures and pointers.

Besides, using typedef for structures is annoying when you try to make
headers self-contained.

Let's say you have the following function declaration in a header:

  void foo(bd_t *bd);

This is not self-contained since bd_t is not defined.

To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>

  #include <asm/u-boot.h>
  void foo(bd_t *bd);

Then, the include direcective pulls in more bloat needlessly.

If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:

  struct bd_info;
  void foo(struct bd_info *bd);

Right, typedef'ing bd_t is a mistake.

I used coccinelle to generate this commit.

The semantic patch that makes this change is as follows:

  <smpl>
  @@
  typedef bd_t;
  @@
  -bd_t
  +struct bd_info
  </smpl>

Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.

Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.

93b3e81212 ARM: kirkwood: remove obsolete call to icache_enable
Commit 93b283d49f ("ARM: CPU: arm926ejs: Consolidate cache routines to
common file") changed cache setup for Kirkwood such that icache_enable()
is now called from enable_caches() which is called from initr_caches()
which is in the list of functions in init_sequence_r[] prior to
arch_misc_init().  This means the call to icache_enable() in
arch_misc_init() is no longer required, so remove it.

The mvebu mbus code already had most of the support required for
kirkwood. The only difference is that unlike the other mvebu targets
kirkwood doesn't have a bridge control block so the code related to
managing that needs to be compiled out.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.
