- * 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.
- *

- * 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.
