This FSP API is called soon after coming out of reset and before memory and stack is
available. This FSP API will load the microcode update, enable code caching for the
region specified by the boot loader and also setup a temporary stack to be used until
main memory is initialized.
A hardcoded stack can be set up with the following values, and the "esp" register
initialized to point to this hardcoded stack.
1. The return address where the FSP will return control after setting up a temporary
stack.
2. A pointer to the input parameter structure
However, since the stack is in ROM and not writeable, this FSP API cannot be called
using the "call" instruction, but needs to be jumped to.
@param[in] TempRaminitParamPtr Address pointer to the FSP_TEMP_RAM_INIT_PARAMS structure.
@retval FSP_SUCCESS Temp RAM was initialized successfully.
@retval FSP_INVALID_PARAMETER Input parameters are invalid..
@retval FSP_NOT_FOUND No valid microcode was found in the microcode region.
@retval FSP_UNSUPPORTED The FSP calling conditions were not met.
@retval FSP_DEVICE_ERROR Temp RAM initialization failed.
If this function is successful, the FSP initializes the ECX and EDX registers to point to
a temporary but writeable memory range available to the boot loader and returns with
FSP_SUCCESS in register EAX. Register ECX points to the start of this temporary
memory range and EDX points to the end of the range. Boot loader is free to use the
whole range described. Typically the boot loader can reload the ESP register to point
to the end of this returned range so that it can be used as a standard stack.

The boot loader provides a continuation function as a parameter when calling FspInit.
After FspInit completes its execution, it does not return to the boot loader from where
it was called but instead returns control to the boot loader by calling the continuation
