061c6d1b23 arm: mvebu: Espressobin: Detect presence of emmc at runtime
Try to initialize emmc in board_late_init() and if it fails then we know
that emmc device is not connected.

This allows to use in U-Boot just one DTS file for all Espressobin variants
and also to correctly set fdtfile env variable for Linux kernel.

a65e65939e arm: mvebu: Espressobin: Setup MTD partitions when booting kernel
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'.

48f2c8a37f arm: mvebu: Espressobin: Disallow forwarding packets between wan and lan ports
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].

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.
