Default env variables on Espressobin boards are broken since commit c4df0f6f31
("arm: mvebu: Espressobin: Set default value for $fdtfile env variable") as well
as the 'env default -a' command.
The algorithm to find free space in the default_environment[] array returns
after the first env variable instead of the correct position of the last
variable, where there is allocated free space.
This causes that U-Boot board_late_init() function to overwrite a portion of the
default environment with $ethXaddr and $fdtfile variables immediately after the
first env variable and so it is overwriting other variables.
This patch also adds an additional null byte to terminate the environment array.
But U-Boot board_late_init() function do not fill this nul byte explicitly. And
because of that, U-Boot is later trying to interpret remaining buffer as a
continuation of variable list. Normally buffer should be empty but due to the
above issue, it contains garbage from remaining env variables.
For example 'env default -a' command results in damaging variable names. It was
observed that scritaddr variable name was changed to criptaddr (without leading
's').
This bug was reported and discussed on the Armbian forum:
https://forum.armbian.com/topic/19564-making-espressobin-v7-work-in-2022/?do=findComment&comment=138136
Fix these issues in two steps:
1) Change code which finds free space for dynamic env variables in
default_environment[] array by jumping to the end of the variable list instead
of jumping after the first defined variable. [By Derek]
2) Add code which appends terminating nul byte as indication of the end of the
env list, after the last nul term env string. [By Pali]

Add a new 'quiet' argument to mmc_get_op_cond() function which avoids
printing error message when SD/eMMC card is not detected.
Espressobin and mx6cuboxi boards use this function for detecting presence
of eMMC and therefore it is expected and normal that eMMC does not have to
be connected. So error message "Card did not respond to voltage select!"
should be skipped in this case as it is not an error.

Ensure that 'env default -a' always set correct value to $fdtfile, even
when custom user variable is already stored in non-volatile env storage
(means that env_get("fdtfile") call returns non-NULL value).
As default value is now correctly set like if specified at compile time in
CONFIG_EXTRA_ENV_SETTINGS, there is no need to set $fdtfile explicitly via
env_set("fdtfile", ...) call.
So remove wrong skip based on env_get("fdtfile") and then also unneeded
env_set("fdtfile", ...) call.

On Espressobin board are MAC addresses stored in U-Boot env area. Therefore
they are not present in default_environment[] array constructed at compile
time.
This change puts permanent MAC addresses into default_environment[] array
at board runtime. Espressobin board has enabled DEFAULT_ENV_IS_RW option
and therefore can modify this array.

Due to different partition layouts in different U-Boot versions, DTS for
Espressobin in Linux does not contain any definition of MTD partitions.
See commit https://git.kernel.org/stable/c/00954566464a4 for more details.
This patch via ft_board_setup() hook fills current partition layout used by
U-Boot, so booted kernel would see correct MTD partitions layout.
U-Boot env partition is calculated from CONFIG_ENV_OFFSET option.
First partition contains secure firmware, ARM trusted firmware and U-Boot
with checksums. So it is not possible to replace just one image (e.g.
U-Boot) without updating other parts where is stored checksum of U-Boot.
Therefore there is no extra partition defined for U-Boot and first
partition is called just 'firmware'.

By default Topaz switch on Espressobin board forwards packets between all
ethernet ports, including CPU (port 0), wan (port 1) and lan (ports 2,3).
This default U-Boot setup is unsuitable for using Espressobin as router as
it opens security hole in forwarding all packets between wan and lan ports.
E.g. dhcp packets from wan network leaks to lan network during small time
window until U-Boot boots Linux kernel which loads network drivers which
disallows forwarding between wan and lan.
This patch fixes above problem. For Espressobin board prior putting Topaz
switch into forwarding mode, Topaz switch is reconfigured to allow
forwarding packets from wan and lan ports only to CPU port. This ensures
that packets from wan port are not forwarded to lan ports and vice-versa.
Packets from CPU port are still forwarded to all other ports, so U-Boot
network boot works with any ethernet port as before.
This problem was already discussed on Espressobin forum [1] and on
Marvell's github issue tracker [2]. As a workaround people on Espressobin
forum patched U-Boot to completely disable lan ports on Topaz switch which
prevented forwarding packets. That workaround had an issue that U-Boot was
unable to netboot via lan ports anymore. Change in this patch does not have
such issue.
This security issue has been dicussed here as well: [3].

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.
