Adding custom SCFW binary (scfw_tcm.bin) to a Yocto build

[guilhermes]

Hello NXP team,

I ported SCFW to a custom board based on the imx8qxp-mek, using the latest SCFW Porting Kit (imx-scfw-porting-kit-1.15.0), generating the scfw_tcm.bin file. My changes to SCFW are basically adapting the DCD table for LPDDR4 (based on MX8QXP_C0_B0_LPDDR4_RPA_1.2GHz_v16). 

I want to set up the build system for this custom board to use this file instead of the default one for the imx8qxp-mek.

Since meta-imx-scfw is not publicly available, how can I include this file as a part of a Yocto build? Should I use the imx-sc-firmware recipe (or any other adequate recipe for this)?
