2023-10-15drivers: introduce Secure Monitor uclassAlexey Romanov
At the moment, we don't have a common API for working with SM, only the smc_call() function. This approach is not generic and difficult to configure and maintain. This patch adds UCLASS_SM with the generic API: - sm_call() - sm_call_write() - sm_call_read() These functions operate with struct pt_regs, which describes Secure Monitor arguments.
