Secure system memory training

A method comprising:

• prior to releasing one or more main processors from reset, a security processor separate from the one or more main processors:
• loading and authenticating multiple blocks of data from a boot media into a first memory of the security processor, wherein at least one block of data includes a first bootloader that comprises a set of executable instructions;
• executing the first bootloader to:
• fetch a further block of data from the boot media, wherein the further block of data comprises a second bootloader wherein the second bootloader is configured to retrieve one or more parameters from the configuration block for initializing and training the system memory;
• and
• store and authenticate the second bootloader in the first memory;
• executing, by the security processor, the second bootloader to initialize and train a system memory.

A non-transitory computer readable storage medium storing program instructions, wherein the program instructions are executable by a processor to:

• load and authenticate multiple blocks of data from a boot media into a first memory of a security processor, wherein at least one block of data includes a first bootloader that comprises a set of executable instructions;
• execute the first bootloader to:
• fetch a further block of data from the boot media, wherein the further block of data comprises a second bootloader, wherein the second bootloader is configured to retrieve one or more parameters from the configuration block for initializing and training the system memory;
• and
• store and authenticate the second bootloader in the first memory;
• execute the second bootloader to initialize and train a system memory.
