From: Marek Behún marek.behun@nic.cz
This device tree is taken from mainline Linux kernel commit 7b7db5ab. Added is also a -u-boot.dtsi file with these additions:
- 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
