NXP SoC supports two TBB mode:
- MBED_TLS based
  -- ROTK key hash is placed as part of the BL2 binary at section:
     --- .rodata.nxp_rotpk_hash
  -- Supporting non-volatile counter via SFP.
     -- platform function used by TFA common authentication code.

- NXP CSF based
  -- ROTK key deployment vary from MBEDTLS

All of the NXP SoC, needs fip_fuse image to be
loaded additionally as part of preparation for Trusted board boot
- fip_fuse.bin contains an image for auto fuse provisioning.
- Auto fuse provisioning is based on the input file with values for:
  -- SRK Hash
  -- OTPMK
  -- misc. refer board manual for more details.

Few of the NXP SoC like LX2160A, needs ddr-phy images to be
loaded additionally before DDR initialization
- fip_ddr.bin is created containing upto 6 ddr images.
- With TRUSTED_BOARD_BOOT = 1, fip_ddr.bin is authenticated
  first before loading and starting DDR initialization.
- To successfully compile this image, platform-defined header files
needs to be defined:
  -- include/common/tbbr/tbbr_img_def.h uses:
	--- plat_tbbr_img_def.h: platform specific new FIP image macros.

  -- include/tools/share/firmware_image_package.h uses:
	--- plat_def_fip_uuid.h: platform specific new UUID macros.
	    ---- Added UUID for DDR images to create FIP-DDR.
	    ---- Added UUID for FUSE provisioning images to create FIP-fuse.

  -- include/tools/share/tbbr_oid.h uses:
	--- platform_oid.h: platform specific new OID  macros.

function load_img(), is dependent on:
- Recursively calling load_image() defined in common/bl_common.c
- for each image in the fip.

NXP specifc macro SET_NXP_MAKE_FLAG is added.

NXP has pool of multiple IPs. This macro helps:
- In soc.mk, this macro help the selected IP source files to be included
  for that SoC.
  -- The set of IPs required for one NXP SoC is different to the set of IPs
     required by another NXP SoC.

- For the same SoC,
  -- For one feature, the IP may be required in both BL2 and BL31.
  -- Without the above feature, that IP may be required in one.
     This macro help in selecting the inclusion of source and header files to:
     --- BL2 only
     --- BL31 only
     --- COMM (used by BL2 and BL31)
