* emulparams/d30velf.sh (STACK_START_ADDR): Top of default
stack.
({TEXT,DATA,EMEM}_SIZE): Sizes of the 3 memory areas.
({TEXT,DATA,BSS}_MEMORY): Which memory region .text, .data, and
.bss should go in.
* scripttempl/elfd30v.sc: Allow .text, .data, .bss to be put in
either the onchip text/data areas or the external memory area.
(MEMORY): Get sizes from d30velf.sh.
(.e{data,text,bss}): Put sections in the external memory region.
(.stext): Put section in the onchip text region.
(.s{data,bss}): Put sections in the onchip data region.
(__stack): Assign from ${STACK_START_ADDR}.
(.text): Put in ${TEXT_MEMORY} memory region.
(.data{,1}/.strings/.rodata{,1}): Put in ${DATA_MEMORY} memory
region.
(.bss): Put in ${BSS_MEMORY} memory region.
