helper functions for SoC 64bits In-Reply-To: <1582264059-37988-1-git-send-email-chee.hong.ang@intel.com> References: <1582264059-37988-1-git-send-email-chee.hong.ang@intel.com> Message-ID: <1582264059-37988-11-git-send-email-chee.hong.ang@intel.com> From: Chee Hong Ang These secure register access functions allow U-Boot proper running at EL2 (non-secure) to access System Manager's secure registers by calling the ATF's PSCI runtime services (EL3/secure). If these helper functions are called from secure mode (EL3), the helper function will direct access the secure registers without calling the ATF's PSCI runtime services.
