+/**\r
+ This FSP API is called soon after coming out of reset and before memory and stack is\r
+ available. This FSP API will load the microcode update, enable code caching for the\r
+ region specified by the boot loader and also setup a temporary stack to be used until\r
+ main memory is initialized.\r
+\r
+ A hardcoded stack can be set up with the following values, and the "esp" register\r
+ initialized to point to this hardcoded stack.\r
+ 1. The return address where the FSP will return control after setting up a temporary\r
+ stack.\r
+ 2. A pointer to the input parameter structure\r
+\r
+ However, since the stack is in ROM and not writeable, this FSP API cannot be called\r
+ using the "call" instruction, but needs to be jumped to.\r

+ @retval FSP_UNSUPPORTED The FSP calling conditions were not met.\r
+ @retval FSP_DEVICE_ERROR Temp RAM initialization failed.\r
+\r
+ If this function is successful, the FSP initializes the ECX and EDX registers to point to\r
+ a temporary but writeable memory range available to the boot loader and returns with\r
+ FSP_SUCCESS in register EAX. Register ECX points to the start of this temporary\r
+ memory range and EDX points to the end of the range. Boot loader is free to use the\r
+ whole range described. Typically the boot loader can reload the ESP register to point\r
+ to the end of this returned range so that it can be used as a standard stack.\r
