The clue is to put the text section into the flash. Here's from my
linker script:

MEMORY
{
  ram    (rwx) : ORIGIN = 512M,       LENGTH = 32K
  flash  (rx)  : ORIGIN = 0,          LENGTH = 256K
  ipsbar (rwx) : ORIGIN = 0x40000000, LENGTH = 0x0
}
...

  .text :
  {
    *(.text .text.*)
    . = ALIGN(0x4);
  } > flash

as well as the rodata:

  .rodata :
  {
    *(.rodata .rodata.*)
    . = ALIGN(0x4);
  } > flash
