Pankaj Gupta 0f33f50e21 nxp: warm reset support to retain ddr content ... NXP: Added warm reset handler to handle SMC PSCI_SYSTEM_RESET2 raised from kernel (> 5.4). As part of first cold boot, DDR training data is stored in NV storage. As part of this SMC handling, following things are done: - DDR is put in self-refresh mode to retain the content of DDR. - Reset cause is saved. - Reset is triggered. On next boot to last warm-reset, DDR training is restored from the NV storage.
