tools: spkgimage: add Renesas SPKG format
Renesas RZ/N1 devices contain BootROM code that loads a custom SPKG
image from QSPI, NAND or USB DFU. Support this format in mkimage tool.
SPKGs can optionally be signed, however creation of signed SPKG is not
currently supported.
Example of how to use it:
tools/mkimage -n board/schneider/rzn1-snarc/spkgimage.cfg \
-T spkgimage -a 0x20040000 -e 0x20040000 \
-d u-boot.bin u-boot.bin.spkg
The config file (spkgimage.cfg in this example) contains additional
parameters such as NAND ECC settings.
