[U-Boot] [PATCH v2 0/6] Support for the Turris Omnia router
This is the second version of patches for adding support for the Turris Omnia board, a router developed by the CZ.NIC.
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, wich small additions.
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.

From: Marek Behún marek.behun@nic.cz
The DDR3 training code for Marvell A38X currently computes 1t timing when given board topology map of the Turris Omnia, but Omnia needs 2t.
This patch adds support for enforcing the 2t timing in struct hws_topology_map, through a new enum hws_timing, which can assume following values: HWS_TIM_DEFAULT - default behaviour, compute whether to enable 2t from the number of CSs HWS_TIM_1T - enforce 1t HWS_TIM_2T - enforce 2t
This patch also sets all the board topology maps (db-88f6820-amc, db-88f6820-gp, controlcenterdc and clearfog) to have timing set to HWS_TIM_DEFAULT.

The Orion watchdog can be found on some Marvell Armada chips.
This driver is based on the code by Tomas Hlavacek in the CZ.NIC turris-omnia-uboot repository, which can be found at https://gitlab.labs.nic.cz/turris/turris-omnia-uboot, and that one is based on code by Sylver Bruneau. His code is already in mainline Linux kernel.
The code uses the new driver model API.

- aliases for I2C devices are added, because u-boot i2cmux doesn't work otherwise - the ATSHA204A node is added in the i2c@5 node - "u-boot,dm-pre-reloc"s are added in needed nodes for SPL build to work correctly

Thanks for that clarification.
with certain modifications:
- aliases for I2C devices are added, because u-boot i2cmux doesn't work otherwise
Sorry, my question may not have been clear enough: You should not add anything to the .dts. Use a new -u-boot.dtsi for any additions instead, so that we can update the .dts file from Linux.
- the ATSHA204A node is added in the i2c@5 node

This module can be found on the Turris Omnia board connected via the I2C interface.
Among some cryptographic functions, the chip has a 512 bit One Time Programmable memory, 88 byte configuration memory and 512 byte general purpose memory.
The Turris Omnia stores serial number and device MAC address in the OTP memory.
This commit adds basic support for reading the EEPROM and also exposes the chips Random Number Generator.
The driver is based on code by Josh Datko, Cryptotronix, jbd@cryptotronix.com and also Tomas Hlavacek, CZ.NIC, tomas.hlavacek@nic.cz

The Turris Omnia is a open-source router created by CZ.NIC.
The code is based on the Marvell/db-88f6820-gp by Stefan Roese with modifications from Tomas Hlavacek in the CZ.NIC turris-omnia-uboot repository, which can be found at https://gitlab.labs.nic.cz/turris/turris-omnia-uboot
By default, the Turris Omnia uses btrfs as the main and only filesystem, and also loads kernel and device tree from this filesystem. Since U-Boot does not yet support btrfs, you should not flash your Turris Omnia board with this unless you know what you are doing.
