*SRAM reserved for bootloader*

Type: ``int``

Help
====

.. code-block:: none

    This option specifies the amount of SRAM (measure in kB) reserved for
    a bootloader image, when either:
    - the Zephyr image itself is to act as the bootloader, or
    - Zephyr is a !XIP image, which implicitly assumes existence of a
    bootloader that loads the Zephyr !XIP image onto SRAM.
