Michael Jung 9b679a7860 stm32l562e-dk: Board Support
Support for the STMicroelectronics STM32L562E-DK development board. This
is a proof-of-concept port that demonstrates running NuttX as the
Non-Secure TrustZone domain companion to TrustedFirmware-M.

/* This linker script supports running NuttX in the 'Non-Secure' (ns) domain
* in conjunction with TrustedFirmware-M (tfm).
*
* NuttX will run as the 'Non secure application' in the 'Non-Secure Image
* primary primary slot Area 1' in external flash. Compare [UM2671],
* Figure 8. Furthermore, see Figure 15 for the SRAM area used for 'Non-
* Secure application volatile data'
*
* While the 'Non-Secure Image primary slot Area 1' is actually one MiB large
* in the referenced setup, the image will be enriched with a header of 0x400
* bytes and a trailer of 0x2000 bytes. Thus the 'flash' statement in the
* MEMORY definition below.
