20b016a336 common: Fix cpu nr type which is always unsigned type
cpu_cmd() is reading cpu number via simple_strtoul() which is always
unsigned type.
Platform code implementations are not expecting that nr can be negative
and there is not checking in the code for that too.

This patch is using u32 type for cpu number to make sure that platform
code get proper value range.

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.

9925f1dbc3 net: Move enetaddr env access code to env config instead of net config
In order that we can use eth_env_* even when CONFIG_NET isn't set, move
these functions to environment code from net code.

This fixes failures such as:

  board/ti/am335x/built-in.o: In function `board_late_init':
  board/ti/am335x/board.c:752: undefined reference to `eth_env_set_enetaddr'
  u-boot/board/ti/am335x/board.c:766: undefined reference to `eth_env_set_enetaddr'

which caters for use cases such as:

commit f411b5cca4 ("board: am335x: Always set eth/eth1addr environment
variable")

when Ethernet is required in Linux, but not U-Boot.

44262327aa drivers/misc: Share qbman init between archs
This patch adds changes necessary to move functionality present in
PowerPC folders with ARM architectures that have DPAA1 QBMan hardware

- Create new board/freescale/common/fsl_portals.c to house shared
  device tree fixups for DPAA1 devices with ARM and PowerPC cores
- Add new header file to top includes directory to allow files in
  both architectures to grab the function prototypes
- Port inhibit_portals() from PowerPC to ARM. This function is used in
  setup to disable interrupts on all QMan and BMan portals. It is
  needed because the interrupts are enabled by default for all portals
  including unused/uninitialised portals. When the kernel attempts to
  go to deep sleep the unused portals prevent it from doing so

c1c3fe2307 env: Convert CONFIG_ENV_IS_IN... to a choice
At present we support multiple environment drivers but there is not way to
select between them at run time. Also settings related to the position and
size of the environment area are global (i.e. apply to all locations).

Until these limitations are removed we cannot really support more than one
environment location. Adjust the location to be a choice so that only one
can be selected. By default the environment is 'nowhere', meaning that the
environment exists only in memory and cannot be saved.

Also expand the help for the 'nowhere' option and move it to the top since
it is the default.

reginfo command is calling mpc8xx_reginfo(), mpc85xx_reginfo()
or mpc86xx_reginfo() based on CONFIG_ symbol.
As those 3 functions can't me defined at the same time, let's
rename them print_reginfo() to avoid the #ifdefs
The name is kept generic as it is not at all dependent on
powerpc arch and any other arch could want to also print
such information.

In addition, as the Makefile compiles cmd/reginfo.c only when
CONFIG_CMD_REGINFO is set, there is no need to enclose the U_BOOT_CMD
definition inside a #ifdef CONFIG_CMD_REGINFO

Lets all remove the #ifdefs around the U_BOOT_CMD as this
file is only compiled when CONFIG_CMD_REGINFO is defined

Finally, this is a PowerPC-only command, disable it on a number of
non-PowerPC platforms.
