From faaa2e7644ec6101de0e7d4f35b9dd2999f110a7 Mon Sep 17 00:00:00 2001 From: Vikram Kanigiri Date: Tue, 15 Jul 2014 16:49:22 +0100 Subject: Support asynchronous method for BL3-2 initialization This patch adds support for BL3-2 initialization by asynchronous method where BL3-1 transfers control to BL3-2 using world switch. After BL3-2 initialization, it transfers control to BL3-3 via SPD service handler. The SPD service handler initializes the CPU context to BL3-3 entrypoint depending on the return function indentifier from TSP initialization.
