Notes: Changes for v6: - RAM initialisation reworked to detect available memory - Remove memory section from am335x-wega-rdk-u-boot.dtsi

Changes for v5: - Revert proposed moving of sections to am33xx-u-boot.dtsi - Remove redundant/incorrect lines from am33xx-u-boot.dtsi - Add missing changelog

Changes for v4: - Propose abstracting common sections to am33xx-u-boot.dtsi - Remove dead Falcon mode code - Remove non-DM I2C support for TPS65910 I2C

Changes for v3: - Added kernel revision of upstream Linux dtsi files - Place TARGET_PHYCORE_AM335X_R2 alphabetically in Kconfig - Rework TPS65910 I2C init code - Remove non-DM USB board macros - Minor tweaks

Changes for v2: - Remove formatting changes to upstream Linux dtsi files - Remove incorrectly added MACH_TYPE - Rename board from phycore_pcl060 to phycore_am335x_r2 - Implement selecting memory size from device tree - Remove non-DM Ethernet board code - General clean-up
