CRS305-1G-4S has a switch chip with an integrated CPU (98DX3236) and
like some of the other similar boards requires bin_hdr.
bin_hdr (DDR3 init stage) is currently retrieved from the stock

There is a Factory RESET button on the back side of the Turris Omnia
router. When user presses this button before powering the device up and
keeps it pressed, the microcontroller prevents the main CPU from booting
and counts how long the RESET button is being pressed (and indicates
this by lighting up front LEDs).
The idea behind this is that the user can boot the device into several
Factory RESET modes.
This patch adds support for U-Boot to read into which Factory RESET mode
the user booted the device. The value is an integer stored into the
omnia_reset environment variable. It is 0 if the button was not pressed
at all during power up, otherwise it is the number identifying the
Factory RESET mode.
This patch also changes bootcmd to a special hardcoded value if Factory
RESET button was pressed during device powerup. This special bootcmd
value sets the colors of all the LEDs on the front panel to green and
then tries to load the rescue image from the SPI flash memory and boot
it.

Testing has shown that the current DM implementation of a platform /
board specific translation offset, as its needed for the SPL on MVEBU
platforms is buggy. The translation offset is confingured too late,
after the driver bind functions are run. This may result in incorrect
address translations. With the current implementation its not possible
to configure the offset earlier, as the DM code has not run at all.
This patch now removed the set_/get_translation_offset() calls and
moves the translation offset into the GD variable translation_offset.
This variable will get used when CONFIG_TRANSLATION_OFFSET is enabled.
This option is enabled only for MVEBU on ARM32 platforms, where its
currenty needed and configured in the SPL.

Compared to the Armada 3700, the Armada 7K and 8K are much more on the
high-end side: they use a dual Cortex-A72 or a quad Cortex-A72, as
opposed to the Cortex-A53 for the Armada 3700.
The Armada 7K and 8K also use a fairly unique architecture, internally
they are composed of several components:
- One AP (Application Processor), which contains the processor itself
and a few core hardware blocks. The AP used in the Armada 7K and 8K
is called AP806, and is available in two configurations:
dual Cortex-A72 and quad Cortex-A72.
- One or two CP (Communication Processor), which contain most of the I/O
interfaces (SATA, PCIe, Ethernet, etc.). The 7K family chips have one
CP, while the 8K family chips integrate two CPs, providing two times
the number of I/O interfaces available in the CP.
The CP used in the 7K and 8K is called CP110.
All in all, this gives the following combinations:
- Armada 7020, which is a dual Cortex-A72 with one CP
- Armada 7040, which is a quad Cortex-A72 with one CP
- Armada 8020, which is a dual Cortex-A72 with two CPs
- Armada 8040, which is a quad Cortex-A72 with two CPs

This adds support for the MV78230 based DS414 NAS by Synology. The
relevant bits have been extracted from the 'synogpl-5004-armadaxp'
package Synology kindly published, garnished with a fair amount of
trial-and-error.
Sadly, support is far from perfect. The major parts I have failed in
are SATA and XHCI support. Details about these and some other things
follow:
Device Tree
-----------
The device tree file armada-xp-synology-ds414.dts has been copied from
Linux and enhanced by recent U-Boot specific changes to
armada-xp-gp.dts.
SATA Support
------------
There is a Marvell 88SX7042 controller attached to PCIe which is
supported by Linux's sata_mv driver but sadly not U-Boot's sata_mv.
I'm not sure if extending the latter to support PCI devices is worth the
effort at all. Porting sata_mv from Linux exceeded my brain's
capacities. :(
XHCI Support
------------
There is an EtronTech EJ168A XHCI controller attached to PCIe which
drives the two rear USB3 ports. After a bit of playing around I managed
to get it recognized by xhci-pci, but never was able to access any
devices attached to it. Enabling it in ds414 board config shows that it
does not respond to commands for whatever reason. The (somewhat) bright
side to it is that it is not even supported in Synology's customized
U-Boot, but that also means nowhere to steal the relevant bits from.
EHCI Support
------------
This seems functional after issuing 'usb start'. At least it detects USB
storage devices, and IIRC reading from them was OK. OTOH Linux fails to
register the controller if 'usb start' wasn't given before in U-Boot.
According to Synology sources, this board seems to support USB device
(gadget?) mode. Though I didn't play around with it.
PCIe Support
------------
This is fine, but trying to gate the clocks of unused lanes will hang
PCI enum. In addition to that, pci_mvebu seems not to support DM_PCI.
DDR3 Training
-------------
Marvell/Synology uses eight PUPs instead of four. Does not look like
this is meant to be customized in mainline U-Boot at all. OTOH I have
no idea what a "PUP" actually is.
PEX Init
--------
Synology uses different values than mainline U-Boot with this patch:
pex_max_unit_get returns 2, pex_max_if_get returns 7 and
max_serdes_lines is set to 7. Not changing this seems to not have an
impact, although I'm not entirely sure it does not cause issues I am not
aware of.
Static Environment
------------------
This allows to boot stock Synology firmware at least. In order to be a
little more flexible when it comes to booting custom kernels, do not
only load zImage partition, but also rd.gz into memory. This way it is
possible to use about 7MB for kernel with piggyback initramfs.

This patch adds runtime detection of the Marvell UART boot-mode (xmodem
protocol). If this boot-mode is detected, SPL will return to the
BootROM to continue the UART booting.
With this patch its now possible, to generate a U-Boot image that
can be booted either from the strapped boot-device (e.g. SPI NOR, MMC,
etc) or via the xmodem protocol from the UART. In the UART case,
the kwboot tool will dynamically insert the UART boot-device type
into the image. And also patch the load address in the header, so
that the mkimage header will be skipped (as its not expected by the
Marvell BootROM).
This simplifies the development for Armada XP / 38x based boards.
As no special images need to be generated by selecting the
MVEBU_BOOTROM_UARTBOOT Kconfig option.
Since the Kconfig option MVEBU_BOOTROM_UARTBOOT is not needed any
