/**
|
|
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] FsptUpdDataPtr Pointer to the FSPT_UPD data structure.
|
|
|
|
@retval EFI_SUCCESS Temporary RAM was initialized successfully.
|
|
@retval EFI_INVALID_PARAMETER Input parameters are invalid.
|
|
@retval EFI_UNSUPPORTED The FSP calling conditions were not met.
|
|
@retval EFI_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.
