boards/imx93-evk: kernel build for AHAB boot
Add kernel build (target imx93-evk:knsh) to i.MX93 EVK.
This target is preconfigured for use with AHAB boot (see
https://spsdk.readthedocs.io/en/latest/examples/ahab/imx93/imx93_ahab_uboot.html)
as a replacement of U-Boot proper (BL33 at EL2), hence
the load address is set to 0x80200000.

3. Insert the SD-card into the imx93-evk, make sure BMODE switch is [1,2,3,4]
= [Off, On, Off, Off] so that it boots from the SD-card.
This should boot into NuttShell in EL3 level.
+
+==========================================
+
+Option 5: Kernel build, via AHAB boot
+
+==========================================
+
+1. Follow the instructions at:
https://spsdk.readthedocs.io/en/latest/examples/ahab/imx93/imx93_ahab_uboot.html
+ to create an eMMC-bootable image (latest version of instructions tested is
v2.6.1). We will be replacing the u-boot binary in step 2.3 with NuttX.
+
+2. Clone both NuttX and NuttX-Apps in same level directories `nuttx` and
`apps` respectively.
+
+3. Configure and build NuttX:
+
+ cd nuttx
+ tools/configure.sh imx93-evk:knsh
+ make
+ make export
+
+4. Build NuttX apps and prepare the /bin ROMFS image:
+
+ pushd ../apps
+ tools/mkimport.sh -z -x ../nuttx/nuttx-export-*.tar.gz
+ make import
+ tools/mkromfsimg.sh
+ mv boot_romfsimg.h
../nuttx/boards/arm64/imx9/imx93-evk/include/bin_romfsimg.h
+ popd
+
+5. Re-build NuttX embedding the generated /bin ROMFS image:
+
+ make clean clean_context
+ make
+
+6. Replace the value of the `u-boot:` entry in workspace/ahab_template.yaml
created in step 1 above with the path to nuttx.bin.
