[PATCH v3 1/4] binman: Add nxp_imx8mcst etype for i.MX8M flash.bin signing
Add new binman etype which allows signing both the SPL and fitImage sections of i.MX8M flash.bin using CST. There are multiple DT properties which govern the signing process, nxp,loader-address is the only mandatory one which sets the SPL signature start address without the imx8mimage header, this should be SPL text base. The key material can be configured using optional DT properties nxp,srk-table, nxp,csf-crt, nxp,img-crt, all of which default the key material names generated by CST tool scripts. The nxp,unlock property can be used to unlock CAAM access in SPL section.

Hi Marek,
I thought you were going to leave the above env setting examples in the documentation.
I suggest showing how to specify using env (by just leaving the above in) as well as by copying them directly to the build directory if wanted.. otherwise the documentation is lacking.
