[PATCH 0/2] arm: mvebu: clearfog: support additional ddr

This series adds support for additional memory configuration that were been produced in the past - most notably a dual-channel configuration with two 512MB modules.
Josua Mayer (2): arm: mvebu: clearfog: read number of ddr channels from tlv data arm: mvebu: clearfog: support 512MB memory size from tlv eeprom

Extend the existing tlv vendor extension used for ram size by one byte to also store the number of ddr channels. The length of the tlv entry can indicate whether the new information is present. If not default to single channel.
