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>

0914011310 command: Remove the cmd_tbl_t typedef
We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.

90526e9fba common: Drop net.h from common header
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.

0a590243d1 arm: mvebu: AXP: Enhance PCIe port capability configuration
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.

54055ff7a6 arm: mvebu: theadorable: Add test for ctrl-c in PCIe PEX switch test
The check for the missing PEX switch can lead to an infinite loop, when
the PCIe device is not found. It is helpful to enable the user to break
out of this boot-loop, to enable booting to the prompt for test cases.
This patch adds a 3 second delay in the error case before rebooting.
The user can press Ctrl-C in this time to abort the boot-loop.

This patch also calls bootcount_inc() before rebooting in the error
case. This is needed to increment the bootcounter, since this function
is called earlier than the main bootcounter increment. Otherwise the
bootcounter will not be incremented in the error case at all.

6d9a98c583 video: Armada XP: Move driver to DM_VIDEO
This patch moves the Armada XP video / LCD driver to DM_VIDEO. With this
move, the legacy interface board_video_init() is removed from the
theadorable board code (only user of this video driver). The support
via DT will be added in a separate patch.

This patch also enables DM_VIDEO for the theadorable board, as this is
needed to not break git bisect'ability.

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

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.

a30d3e7777 arm: mvebu: Remove theadorable_defconfig
Currently, we support 2 "theadorable" MVEBU build targets. One with a
stripped down configuration (theadorable) and one with a full blown
configuration (theadorable_debug), including PCI, ethernet etc. When
we introduced these configs, the plan was to remove the debug version
at some point. But now it seems better to keep the full-blown version
and remove the "non-debug" version instead.

At a later stage, I will rename the remaining "theadorable_debug"
target into a more fitting one.

device (via vendor-ID and device-ID). If the device is not detected,
this will get printed. If the device is detected, the board will get

Define a board-specific detection pulse-width array for the SerDes PCIe
interfaces. If not defined in the board code, the default of currently 2
is used. Values from 0...3 are possible (2 bits).

In this case of the theadorable board, PEX interface 0 needs a value
of 0 for the detection pulse width so that the PCIe device (Atheros
WLAN PCIe device) is consistantly detected.

the board is not in a usable state. This patch makes sure that in this
