[coreboot] [arm64] queries on current support and future direction

[Sukanto Ghosh]

Hi Everyone,

We have couple of queries regarding the current support and future direction of arm64 port of coreboot:

1.  Does the current coreboot/arm64 execute post BL31 stage (assuming a separate BL2 stage loads BL31 and coreboot) ?
     *   If no, would coreboot community be willing to support such a flow (via a build-time flag) ?
     *   Beyond the direct access of EL3 registers, what are the other assumptions that the current coreboot/arm64 port has that need to be addressed to allow such a NS-EL2 port ?
  2.  Does the current coreboot/arm64 port allow executing only the ramstage of coreboot (say as a means of reducing the coreboot binary footprint) ?

Best Regards,
Sukanto
