This is the fourth version of patches for adding support for the
Turris Omnia board, a router developed by the CZ.NIC.
Modifications from last version:
- Since the new driver model API does not expose the
watchdog_reset function, only wdt_reset, the watchdog did not
get restarted and the device rebooted every 2 minutes in U-Boot.
These patches solve this problem.
- The SPI flash could not be accessed. I did not notice this since
during my testing I always uploaded the SPL image via serial
line. This is now also solved.
The first patch modifies Marvell's DDR3 training code to be more
general, so that board topology map can force 2t timing.
The second patch adds support for the hardware watchdog which
can be found on Omnia. I have modified the driver to use the new
driver model API.
The third patch adds the device tree for Turris Omnia taken from
Linux kernel and also armada-385-turris-omnia-u-boot.dtsi file
with some additions for U-Boot.
The fourth patch adds support for the I2C multiplexer found on
Turris Omnia.
The fifth patch adds support for the ATSHA204A CryptoAuthentication
chip, on which the Turris Omnia stores serial number and device MAC
address.
The sixth patch adds the proper support for the board. I have
modified config to use distro defaults as requested by Andreas
Faerber and also removed unnecessary comments.
