This looks like a modified copy of bsps/arm/shared/start/linkcmds.base.
Are there significant differences or could we share this linker script on arm
and aarch64?
[]
They are similar and could probably share large sections, but a single base
linker script is not shareable between arm and aarch64 due to aarch64 multilibs
needing different OUTPUT_FORMAT and OUTPUT_ARCH directives as well as having
differing setups for their various respective exception stacks.
Can't this be solved via an INCLUDE similar to linkcmds.armv4 and
linkcmds.armv7m?
