# To let the nRF5 bootloader load an application, the application
# must be linked after Nordic MBR, that is factory-programmed on the board.

# Nordic nRF5 bootloader exists outside of the partitions specified in the
# DTS file, so we manually override FLASH_LOAD_OFFSET to link the application
# correctly, after Nordic MBR.

# When building MCUBoot, MCUBoot itself will select USE_DT_CODE_PARTITION
# which will make it link into the correct partition specified in DTS file,
# the offset is applied here so that the full partition size can be used when
# the bootloader Kconfig option has been disabled.
