---------------------------------------------------------------------------------------
Properties / Entry arguments:
- filename: Filename of file to read into entry
This file contains a binary blob which is used on some devices to set up
temporary memory (Cache-as-RAM or CAR). U-Boot executes this code in TPL so
that it has access to memory for its stack and initial storage.
An example filename is 'fsp_t.bin'
