2019-03-04device/mmio.h: Add include file for MMIO opsKyösti Mälkki
MMIO operations are arch-agnostic so the include path should not be arch/.

2019-02-26soc/cavium/cn81xx: Enable RNG for DRAM initPatrick Rudolph
The Cavium DRAM init might use the RNG for pattern generation. Initialize it before running DRAM init. Tested on OpenCellular Elgon. The RNG generates non identical numbers.

2018-07-23soc/cavium: Enable DRAM testPatrick Rudolph
Enable fast or extended DRAM test based on devicetree setting. The fast DRAM test takes less than a second, while the extended runs about 1 minute. Tested on Cavium Soc.

2018-07-10cavium: Add CN81xx SoC and eval board supportDavid Hendricks
This adds Cavium CN81xx SoC and SFF EVB files. Code is based off of Cavium's Octeon-TX SDK: https://github.com/Cavium-Open-Source-Distributions/OCTEON-TX-SDK BDK coreboot differences: bootblock: - Get rid of BDK header - Add Kconfig for link address - Move CAR setup code into assembly - Move unaligned memory access enable into assembly - Implement custom bootblock entry function - Add CLIB and CSIB blobs romstage: - Use minimal DRAM init only devicetree: - Convert FTD to static C file containing key value pairs Tested on CN81xx: - Boots to payload - Tested with GNU/Linux 4.16.3 - All hardware is usable (after applying additional commits) Implemented in future commits: - Vboot integration - MMU suuport - L2 Cache handling - ATF from external repo - Devicetree patching - Extended DRAM testing - UART init Not working: - Booting a payload - Booting upstream ATF TODO: - Configuration straps Change-Id: I47b4412d29203b45aee49bfa026c1d86ef7ce688 Signed-off-by: David Hendricks <dhendricks@fb.com> Signed-off-by: Patrick Rudolph <patrick.rudolph@9elements.com> Reviewed-on: https://review.coreboot.org/23037 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: David Hendricks <david.hendricks@gmail.com>
