/****************************************************************
* Memory map configuration for using application with MCU-boot *
****************************************************************/
/*
* Internal nRF52 flash memory:
* 0x00000000: MCUBoot(28 kB)
* 0x00007000: Reboot logs (4 kB)
* 0x00008000: MCUBoot header (32 bytes)
* 0x00008020: Application (463+ kB)
* 0x0007be50: MCUBoot image trailer (432 bytes)
* 0x0007c000: MCUBoot Scratch partition (4 kB)
* 0x0007d000: unused (12 kB)
*
* SPI flash:
* 0x00000000: Bootloader Assets, like Boot Graphic (256 kB)
* 0x00040000: Application 2 (including MCUBoot header) (464 kB)
* 0x000b4000: User files - littlefs (3376 kB)
*
* This linker script sets the origin of the application at 0x00
* which means that the application must be linked with a start
* address at 0x00 and that it'll overwrite the bootloader.
* This is very practical when debugging and testing on
* the hardware with a SWD probe.
