Note that PCIE_ECAM_BASE is set up by the FSP so the value used
by U-Boot matches that value.
+config TARGET_SLIMBOOTLOADER
+ bool "slimbootloader"
+ help
+ This target is used for running U-Boot on top of Slim Bootloader
+ boot firmware as a payload. Slim Bootloader does memory initialization
+ and silicon initialization, and it passes necessary information in
+ HOB (Hand Off Block) to a payload. The payload consumes HOB data
+ which is generated by Slim Bootloader for its driver initialization.
+ Slim Bootloader consumes FSP and its HOB, but FSP HOB is cleared
+ Before launching a payload. Instead, Slim Bootloader generates its
+ HOB data such as memory info, serial port info and so on.
+ Refer to doc/board/intel/slimbootloader.rst for the details.
