env.h says this about about callback declarations (U_BOOT_ENV_CALLBACK):
* For SPL these are silently dropped to reduce code size, since environment
* callbacks are not supported with SPL.
So env_callback_init() does a lot of work to not find anything in the
guaranteed empty env_clbk list. Drop callback.o entirely from the link
and stub out the only public function defined in callback.o. This cuts
about 600 bytes from the SPL on my ppc build.

Some environment variables are relevant for networking. For these
U_BOOT_ENV_CALLBACKs have been defined. When the corresponding environment
variable is updated the callback updates the state of the network
sub-system.
In the UEFI subsystem we can use the network even if CONFIG_CMD_NET is not
defined.
Let the usage of the U_BOOT_ENV_CALLBACKs depend on CONFIG_NET and not on
CONFIG_CMD_NET.

U-Boot is not supposed to use typedef for structs anymore. Also this name
is the same as the ENTRY() macro used in assembler files, and 'entry'
itself is widely used in U-Boot (>8k matches).
Drop the typedef and rename the struct to env_entry to reduce confusion.

These definitions are effectively part of the 'public' API of the
environment implementation since they do not require access to any
internal variables. Move them to the env.h header.

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.

Since commit 842778a09104 ("usb: gadget: g_dnl: only set iSerialNumber
if we have a serial#") "fastboot devices" stopped to show correct device
serial number for TI boards, showing this line instead:
???????????? fastboot
This is because serial# env variable could be set after g_dnl gadget was
initialized (e.g. by using env_set() in the board file).
To fix this, let's update internal serial number variable (g_dnl_serial)
when "serial#" env var is changed.

Instead of selecting REGEX when NET is enabled, make it the default, but
allow boards that are tiny to disable it and lose functionality on all
but the first Ethernet adapter.
cm-bf548, bf538f-ezkit, and bf533-stamp need this. None appear to have
more than one Ethernet interface.

When the ethaddr is changed in the env, update the device pdata at the
same time (only if it is probed for the DM case; only if registered for
the non-DM case). Again this gets us closer to completely non-polled
env needed to simplify the net_loop.
This requires that the NET feature select the REGEX feature.

Instead of checking for changes to the env each time we enter the
net_loop, use the env callbacks to update the values of the variables.
Don't update the variables when the source was programmatic, since the
variables were the source of the new value.

When static inline is used in a header file the function
should preferably be inlined and if not possible made a
static function. When declared inside a c file there is a
static function, which might be inlined. Since SPL uses a
define to declare the static inline it becomes part of the
c file although it is declared in a header and clang will
warn that you have introduced unused static functions. Add
maybe_unused to prevent such warnings.

Refactor linker-generated array code so that symbols
which were previously linker-generated are now compiler-
generated. This causes relocation records of type
R_ARM_ABS32 to become R_ARM_RELATIVE, which makes
code which uses LGA able to run before relocation as
well as after.
Note: this affects more than ARM targets, as linker-
lists span possibly all target architectures, notably
PowerPC.

SPL doesn't write to the environment. These list entries prevent the
functions from being garbage-collected, even though nothing will look at
the list. This caused several SPL builds (e.g. P2020RDB-PC_NAND) to
break due to size limitations and/or unresolved symbols.
A static inline function is used to provide a context in which we
can consume the callback, and thus avoid unused function warnings.

Currently just validates variable types as decimal, hexidecimal,
boolean, ip address, and mac address.
If the entry is not found in the env ".flags", then look in the static
one. This allows the env to override the static definitions, but prevents
the need to have every definition in the environment distracting you.
