Ali Saidi f2642e2055 Loader: Make the load address mask be a parameter of the system rather than a constant.
This allows one two different OS requirements for the same ISA to be handled.
Some OSes are compiled for a virtual address and need to be loaded into physical
memory that starts at address 0, while other bare metal tools generate
images that start at address 0.
