1 Samsung Exynos SYSRAM for SMP bringup:
2 ------------------------------------
4 Samsung SMP-capable Exynos SoCs use part of the SYSRAM for the bringup
5 of the secondary cores. Once the core gets powered up it executes the
6 code that is residing at some specific location of the SYSRAM.
8 Therefore reserved section sub-nodes have to be added to the mmio-sram
9 declaration. These nodes are of two types depending upon secure or
10 non-secure execution environment.
12 Required sub-node properties:
13 - compatible : depending upon boot mode, should be
14 "samsung,exynos4210-sysram" : for Secure SYSRAM
15 "samsung,exynos4210-sysram-ns" : for Non-secure SYSRAM
17 The rest of the properties should follow the generic mmio-sram discription
18 found in Documentation/devicetree/bindings/sram/sram.txt
