On Hi6220, below memory regions in DDR have specific purpose: 0x05e0,0000 - 0x05ef,ffff: For MCU firmware using at runtime; 0x06df,f000 - 0x06df,ffff: For mailbox message data; 0x0740,f000 - 0x0740,ffff: For MCU firmware's section; 0x3e00,0000 - 0x3fff,ffff: For OP-TEE. This patch reserves these memory regions in DT.
