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.

@retval EFI_NOT_FOUND No valid microcode was found in the microcode region.

@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.
