+ * We defined several plat parameter structs for BL2 to pass platform related
+ * parameters to Rockchip BL31 platform code. All plat parameters start with
+ * a common header, which has a type field to indicate the parameter type, and
+ * a next pointer points to next parameter. If the parameter is the last one in
+ * the list, next pointer will points to NULL. After the header comes the
+ * variable-sized members that describe the parameter. The picture below shows
+ * how the parameters are kept in memory.
+ *
+ * head of list ---> +----------------+ --+
+ * | type | |
+ * +----------------+ |--> struct bl31_plat_param
+ * +----| next | |

+ * | | parameter data |

+ * | type | |
+ * +----------------+ |--> struct bl31_plat_param
+ * NULL <---| next | |
+ * +----------------+ --+
+ * | parameter data |
+ * +----------------+
+ *
+ * Note: The SCTLR_EL3.A bit (Alignment fault check enable) of ARM TF is set,
+ * so be sure each parameter struct starts on 64-bit aligned address. If not,
+ * alignment fault will occur during accessing its data member.
