This adds a proper glue driver for the Designware DWMAC ethernet MAC IP
found in the Amlogic Meson8, GXBB, GXL, GXM, G12A, G12B & SM1 SoCs.
This is aimed to replace the static ethernet link setup found on the board
init code for the Amlogic SoC based boards.
Tested on a libretech-cc (S905x Internal RMII 10/100 PHY) and Khadas VIM3 (A113d
with external 10/100/1000 RGMII PHY) to cover the most extreme setups.

Espressobin had disabled watchdog support (CONFIG_WDT) because older stable
Linux kernel versions (which are used by current stable OpenWRT and Debian
versions) do not have support for Armada 3700 watchdog driver. Therefore
they are not able to periodically kick watchdog so Espressobin enter into
boot loop.
This change enable CONFIG_WDT, CONFIG_WDT_ARMADA_37XX and CONFIG_CMD_WDT
options which add support for U-Boot 'wdt' command. And unset new
CONFIG_WATCHDOG_AUTOSTART option which cause that watchdog is not
automatically started by U-Boot during init phase, like when CONFIG_WDT
option is not set at all.
So with this change, U-Boot on Espressobin would have working 'wdt' command
which can be used from boot scripts (e.g. for enabling watchdog prior new
Linux booting kernel). But default behavior of watchdog status stays
unchanged, U-Boot does not start watchdog on Espressobin during its init
phase.

In some cases it is useful to compile support for U-Boot command 'wdt'
without starting HW watchdog in early U-Boot phase. For example when the
user want to start the watchdog only on demand by some boot script.
This change adds a new compile option WATCHDOG_AUTOSTART to control whether
U-Boot should automatically start the watchdog during init phase or not.
This option is enabled by default as it was the default behavior prior
introducing this new change. When compiling U-Boot users can decide to turn
this option off.

Watchdog is ready after successful call of ops->start() callback in
wdt_start() function. And is stopped after successful call of ops->stop()
callback in wdt_stop function.
So move setting of GD_FLG_WDT_READY flag from initr_watchdog() function to
wdt_start() and ensure that GD_FLG_WDT_READY flag is unset in wdt_stop()
function.
This change ensures that GD_FLG_WDT_READY flag is set only when watchdog is
running. And ensures that flag is also also when watchdog was started not
only by initr_watchdog() call (e.g. by U-Boot 'wdt' command).

We had a problem detecting 8/16bit flash devices connected only via
8bits to the SoC for quite a while. Commit 239cb9d9
[mtd: cfi_flash: Fix CFI flash driver for 8-bit bus support] finally
fixed this 8-bit bus support. But also broke some other boards using
this cfi driver. So this patch had to be reverted.
I spotted a different, simpler approach for this 8-bit bus support
on the barebox mailing list posted by
Oleksij Rempel <bug-track@fisher-privat.net>:
http://www.spinics.net/lists/u-boot-v2/msg14687.html
Here the commit text:
"
Many cfi chips support 16 and 8 bit modes. Most important
difference is use of so called "Q15/A-1" pin. In 16bit mode this
pin is used for data IO. In 8bit mode, it is an address input
which add one more least significant bit (LSB). In this case
we should shift all adresses by one:
For example 0xaa << 1 = 0x154
"
This patch now is a port of this barebox patch to U-Boot.
Along with the change w.r.t from barebox,
Some flash chips can support multiple bus widths, override the
interface width and limit it to the port width.
Tested on 16-bit Spansion flash on sequoia.
Tested 8-bit flashes like 256M29EW, 512M29EW.

Also if a node's parent is missing the #address-cells and #size-cells

When test suite tries to create a file for a new filesystem test case and fails,
the clean up of the exception tries to unmount the image, that has not yet been
mounted. When it happens, the fuse_mounted global variable is set to False and
inconveniently the test case tries to use sudo, so without this change the
admin of the machine gets an (annoying) email:
Subject: *** SECURITY information for example.com ***
example.com : Feb 5 19:43:47 : ... COMMAND=/bin/umount .../build-sandbox/persistent-data/mnt
and second run of the test cases on uncleaned build folder will ask for sudo
which is not what expected.
Besides that there is a double unmount calls during successfully run test case.
All of these due to over engineered Python try-except clause and people didn't
get it properly at all. The rule of thumb is that don't use more keywords than
try-except in the exception handling code. Nevertheless, here we adjust code
to be less intrusive to the initial logic behind that complex and unclear
constructions in the test case, although it adds a lot of lines of the code,
i.e. splits one exception handler to three, so on each step we know what
cleanup shall perform.

Loading Trusted-Firmware's BL31 at 16KB into DRAM was originally a hack
to allow sharing more code with the other SoCs (which use this offset
in SRAM). However there is no longer a reason for that, as the
problematic macros have been properly separated there.
The latest (and hopefully final) TF-A code drop now changes the load
address to the beginning of DRAM, which is also more easily protected
by the Trustzone memory controller (code to be done).
Adjust the load address of BL31 now, to avoid any issues with
incompatible versions later on (the TF-A patches are about to be merged).
