/**
|
|
This FSP API is called after TempRamInit and initializes the memory.
|
|
This FSP API accepts a pointer to a data structure that will be platform dependent
|
|
and defined for each FSP binary. This will be documented in Integration guide with
|
|
each FSP release.
|
|
After FspMemInit completes its execution, it passes the pointer to the HobList and
|
|
returns to the boot loader from where it was called. BootLoader is responsible to
|
|
migrate it's stack and data to Memory.
|
|
FspMemoryInit, TempRamExit and FspSiliconInit APIs provide an alternate method to
|
|
complete the silicon initialization and provides bootloader an opportunity to get
|
|
control after system memory is available and before the temporary RAM is torn down.
|
|
|
|
@param[in] FspmBase The base address of FSPM.
|
|
@param[out] HobListPtr Pointer to receive the address of the HOB list.
|
|
|
|
@retval EFI_SUCCESS FSP execution environment 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 FSP initialization failed.
|
|
@retval EFI_OUT_OF_RESOURCES Stack range requested by FSP is not met.
|
|
@retval FSP_STATUS_RESET_REQUIREDx A reset is reuired. These status codes will not be returned during S3.
