Since S400 will set the memory of SPL image to R/X. We can't write to any data in SPL image. 1. Set the parameters save/restore only for u-boot, not for SPL. to avoid write data. 2. Not use MU DM driver but directly call MU API to send release XRDC to S400 at early phase. 3. Configure the SPL image memory of SRAM2 to writable (R/W/X) Signed-off-by: Ye Li <ye.li@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>
