-DXXX on the linker command line overrides the defaults
The problem with this approach is that the linker has no ability to detect
region overflows.

Does the NGMP allow for variant sizes of ROM and RAM? If so will we
provide separate BSP variants for all possibilities, or how does the
user select the right size for their board?
The user has to provide an application specific linker command file, e.g.
LDFLAGS += -qnolinkcmds -T linkcmds.app
linkcmds.app:
MEMORY {
ram : ORIGIN = 0x00000000, LENGTH = 12345678M
}
INCLUDE linkcmds.base
