Method and apparatus for an original equipment manufacturer defined scalable and safe memory layout firmware

A method of booting an information handling system, comprising:

• executing, with a central processing unit (CPU), a boot sequence with plural stages of boot modules from a non-volatile memory device;
• executing, with the CPU, an original equipment manufacturer (OEM)-defined agnostic memory allocation module to generate a virtual memory interface at a serial-peripheral interface (SPI) chip to create a customized set of allocated, reserved portions of a memory device for the plural stages of the boot modules;
• and
• the CPU executing the OEM-defined agnostic memory allocation module to redefine the virtual memory interface at the SPI chip to redefine a portion of at least one allocated, reserved portion of the memory device designated for at least a first boot module of the plural stages of the boot modules that are executed from pre-boot, through boot, and to runtime to a second boot module of the plural stages of the boot modules with scalable memory headers for the CPU to access the redefined portion of at least one allocated, reserved portion of the memory device.

An information handling system comprising:

• a central processing unit (CPU);
• the SPI chip to establish a virtual memory interface for the CPU executing the plural stages of boot modules during a boot process of the information handling system to allocate reserved portions of the memory device for each stage of boot module executed in pre-boot, boot, and runtime phases;
• the CPU to execute an original equipment manufacturer (OEM)-defined agnostic memory allocation firmware module generate the virtual memory interface for a customized set of allocated reserved portions of the memory device for the plural stages of the boot modules defined by an OEM via an adjustable memory map;
• the CPU executing the OEM defined agnostic memory allocation firmware module to redefine the adjustable memory map for use with the virtual memory interface for a plurality of allocated reserved portions of the memory device assigned to the plural stages of the boot modules that are executed from pre-boot, through boot, and to runtime phases to provide adjustments to allocated, reserved portions of memory for later stages of executed plural stages of the boot modules;
• and
• the CPU executing the OEM-defined agnostic memory allocation firmware module to create dynamic and customized macros that define the adjustable memory map for use after the information handling system has been rebooted.
