# Code Partition:
#
# For the secure version of the board the firmware is linked at the beginning
# of the flash, or into the code-partition defined in DT if it is intended to
# be loaded by MCUboot. If the secure firmware is to be combined with a non-
# secure image (TRUSTED_EXECUTION_SECURE=y), the secure FW image shall always
# be restricted to the size of its code partition.
#
# For the non-secure version of the board, the firmware
# must be linked into the code-partition (non-secure) defined in DT, regardless.
# Apply this configuration below by setting the Kconfig symbols used by
# the linker according to the information extracted from DT partitions.

# SRAM Partition:
#
# If the secure firmware is to be combined with a non-secure image
# (TRUSTED_EXECUTION_SECURE=y), the secure FW image SRAM shall always
# be restricted to the secure image SRAM partition (sram-secure-partition).
# Otherwise (if TRUSTED_EXECUTION_SECURE is not set) the whole sram0 may be
# used by the image.
#
# For the non-secure version of the board, the firmware image SRAM is
# always restricted to the allocated non-secure SRAM partition.
#
