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.

00caae6d47 env: Rename getenv/_f() to env_get()
We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.

Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

b2f2c7be34 km/ivm: allow to set locally administred MAC addresses
It is possible to flag MAC addresses as locally administred. In this
case they don't need to be unique. This is only allowed for interfaces
which have no connection to the outside. For the TEGR1 board we use
this feature.

b63d4f34d0 km/ivm: always set ethaddr after reading IVM
If we rebrand the IVM and ethaddr was set previously we need to change
ethaddr. Otherwise we end up with a wrong MAC adress for the ethernet
interface.

60c4ae00be KM/IVM: remove ivm_read_eeprom(void)
This is not used anymore since the procedure was split into a simple
read function and a later alaysis.

The ivm_read_eeprom name is now used for the previous
ivm_simple_read_eeprom function.

16ac90c7ee KM/IVM: split the IVM reading and parsing in 2 parts
This allows to first read the IVM content (earlier in the boot sequence)
and define the ethaddr env variable thanks to the ivm_read_eepromi().
Later, the IVM content can be parsed and used to define some hush
variables, when the hush subsystem is available thanks to
ivm_analyze_eeprom().

To avoid the HW read to happen twice, the buffer passed to
ivm_read_eeprom() has to be reused by ivm_analyze_eeprom (and thus
allocated before calling ivm_read_eeprom()).

2716077cda board:keymile: remove unnecessary double braces
Clang interpretes an if condition like  "if ((a = b) == NULL)
as it tries to assign a value in a statement. Hence if you do
"if ((something)) it warns you that you might be confused.
Hence drop the double braces for plane if statements.

5bcd64cf5c powerpc/83xx/km: add MV88E6122 switch support for kmvect1
kmvect1 has a UEC2 connection to the piggy board and a UEC0 connection
to the switch MV88E6122. This switch has a connection to a frontport
ethernet interface. The ethernet port used for network booting is
automatically selected by u-boot. If a Piggy is plugged, the Piggy
port is selected (UEC2, eth1). If the Piggy isn't present, the
Frontport is selected (UEC0, eth0).

The switch reset is connected to a GPIO on the PRIO3 board FPGA (GPIO28)
and released at startup.

62c9b9603e km/ivm: fix string len check to support 7 char board names
The fanless boards now have a 7-digit (XXXXX-F) board name. This
triggers a border condition when reading this string in the IVM although
this string is smaller than the currenly read string size, but only by 1
character.

This patch corrects this by changing the size check condition for string
length. It is the same change that was done in the platform for this
same bug.
