2015-03-21libpayload arm64: Initialize and enable MMUFurquan Shaikh
What this change does: 1) Initialize limited page tables as soon as we jump into libpayload. Basically two ranges are initialized. One is for the BASE_ADDRESS and other is for the coreboot_tables. With page tables initialized and MMU enabled, we jump into code to parse coreboot tables. 2) Once coreboot tables are parsed and we have complete picture of the memory, we perform a complete page table initialzation and enable MMU and then jump to payload. Additionally, we also: 1) Initialize DMA memory on our own depending upon the memory map. It ensures that the DMA buffer is placed in 32-bit memory.

2015-03-21chromeec: provide proto v3 over i2c supportAaron Durbin
Certain boards need to speak proto v3 over i2c. Leverage the transport agnostic API to share the logic with other proto v3 impelementations. BUG=chrome-os-partner:31148 BRANCH=None TEST=Built and ran on ryu. Can talk to the EC successfully.

2015-03-21chromeec: allow transport implementation to provide buffers for proto v3Aaron Durbin
Depending on the transport mechanism for proto v3 different bytes need to be send and/or read before the request and response. Depending on the software and/or controller interface that requirement leads to needing to copy data into temporary buffers. Avoid this by allowing the transport mechanism to provide the request and response buffers. BUG=chrome-os-partner:31148 BRANCH=None TEST=Built for rush and ryu. Ran on ryu with i2c implementation. Also built for rambi to check x86 systems.

2015-03-21chromeec: correct response length for VBNV writeAaron Durbin
The EC doesn't return any data when one performs a write to VBNV context. Therefore there is a mismatch of expectations. Correct this by properly setting the expected response length. BUG=chrome-os-partner:31148 BRANCH=None TEST=No longer hanging while writing to VBNV on ryu.
