Julius Werner b852d229f3 Introduce lightweight BL platform parameter library This patch adds some common helper code to support a lightweight platform parameter passing framework between BLs that has already been used on Rockchip platforms but is more widely useful to others as well. It can be used as an implementation for the SoC firmware configuration file mentioned in the docs, and is primarily intended for platforms that only require a handful of values to be passed and want to get by without a libfdt dependency. Parameters are stored in a linked list and the parameter space is split in generic and vendor-specific parameter types. Generic types will be handled by this code whereas vendor-specific types have to be handled by a vendor-specific handler function that gets passed in.
