Normally, this is simple to address via hybrid partition tables. I've done that already for two different SoCs (TI AM62 and Altera Cyclone V), and this allows to use all the nifty features of the modern GPT without upsetting the ROM loaders. Do you have a SoC where this does not work? That said, adding this feature may still be valuable. Jan -- Siemens AG, Foundational Technologies Linux Expert Center
