Why? xtensa doesn't use any of it.

For xtensa that address is defined as an expression, like
(CONFIG_SYS_MEMORY_TOP - CONFIG_SYS_MONITOR_LEN),
and for a single board it may vary with the CPU core on that board.
If I just do this replacement then linking fails because of this symbolic
definition:

  xtensa-dc233c-elf-ld.bfd    --gc-sections -Bstatic
--no-dynamic-linker -Ttext "(CONFIG_SYS_MEMORY_TOP -
CONFIG_SYS_MONITOR_LEN)"
  ...
  xtensa-dc233c-elf-ld.bfd: invalid hex number `(CONFIG_SYS_MEMORY_TOP
- CONFIG_SYS_MONITOR_LEN)'

Thanks.
