If the SCIF is receiving data quickly enough, it may happen that the
SCxSR_RDxF flag is cleared in sh_serial_getc_generic(), while the
FIFO still contains data. If that happens, the serial_getc_check()
reports no data in the FIFO as the flag is no longer set. Add one
more check, if the SCxSR_RDxF is not set, read out the FIFO level
and if there are still characters in the FIFO, permit reading them

The command 'mtrr' does not recognize the 'list' subcommand any more
since the code restructuring in commit b2a76b3fe7 ("x86: mtrr:
Restructure so command execution is in one place").
The if-else parsing the command arguments does not take 'list' into
account: the if-branch is intended for no subcommands, the else-branch
is intended for the non-list subcommands (which all expect additional
arguments). Calling the 'mtrr list' subcommand leads to a "return
CMD_RET_USAGE" in the else-branch.
Fix this by changing the else-branch to explicitly checking for
if (cmd != 'l').

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'.

Linux kernel pci-aardvark driver needs to reset PCIe card via PERST# signal

This commit fixes initialization of COMPHY on EspressoBin.
Commit 22f418935b ("phy: marvell: a3700: Use comphy_mux on Armada
37xx.") introduced usage of comphy_mux on Armada 37xx comphy driver.
The lanes are defined in comphy_a3700.c as described in functional
specification, that is:
lane 0 is SGMII1 or USB3
lane 1 is PCIe or SGMII0
lane 2 is SATA or USB3
But the DTS for EspressoBin configures PCIe on lane 0 and USB3 on
lane 1, which is wrong in the sense of the specification and doesn't
work with the comphy_mux code, which is 2 years now (the aardvark driver
causes synchronous abort in U-Boot).
It worked till the above mentioned commit, because the code for powering
up PCIe PHY doesn't work with lane number at all, and the code for
powering up USB3 PHY works differently only if USB3 is on lane 2, ie.
the check goes like:
if (lane == 2)
something
else
something else
so it does not differentiate between lanes 0 and 1.
In the future I shall post patches that remove the comphy_a3700 driver
and add comphy driver which uses calls to ATF, like Linux' driver does.
This will have the advantage of same DTS bindings as Linux', but till
this is done, we need this patch.

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].
