From 6fba6e0490584036fe1210986d6db439b22cb03e Mon Sep 17 00:00:00 2001 From: Tony Xie Date: Fri, 15 Jan 2016 17:17:32 +0800 Subject: [PATCH] Support for Rockchip's family SoCs This patch adds to support the RK3368 and RK3399 SoCs. RK3368/RK3399 is one of the Rockchip family SoCs, which is an multi-cores ARM SoCs. This patch adds support to boot the Trusted Firmware on RK3368/RK3399 SoCs, and adds support to boot secondary CPUs, enter/exit core power states for all CPUs in the slow/fast clusters. This is the initial version for rockchip SoCs.(RK3368/RK3399 and next SoCs) * Support arm gicv2 & gicv3. * Boot up multi-cores CPU. * Add generic CPU helper functions. * Support suspend/resume. * Add system_off & system_reset implementation. * Add delay timer platform implementation. * Support the new porting interface for the PSCI implementation.
