From: Mingkai Hu Mingkai.Hu@freescale.com
The Freescale C29x family is a high performance crypto co-processor. It combines a single e500v2 core with necessary SEC engine. There're three SoC types(C291, C292, C293) with the following features:
- 512K L2 Cache/SRAM and 512 KB platform SRAM - DDR3/DDR3L 32bit DDR controller - One PCI express (x1, x2, x4) Gen 2.0 Controller - Trust Architecture 2.0 - SEC6.0 engine
Signed-off-by: Mingkai Hu Mingkai.Hu@freescale.com Signed-off-by: Po Liu Po.Liu@freescale.com --- Changes for v2: - Remove define CONFIG_C291/CONFIG_C292/CONFIG_C293, replace with CONFIG_C29X Changes for v3: - Replace CONFIG_C29X with CONFIG_PPC_C29X Changes for v4: - None Changes for v5: - None
