The eMMC / SD Card methods of BootROM loader are deprecated in the StarFive JH-7110 Technical Reference Manual. Please migrate to using SPI NOR flash or UART boot methods that are supported. The lack of support for this method is intentional as a result of non-compliance in the upstream code review process. In response to the request to support these deprecated methods I asked for supporting documentation in the form of BootROM source code (for which StarFive is in violation of GPL2.0+ by the way, it is required to publish source of modifications and StarFive have not done this). If we want to support this deprecated mode I will agree when GPL compliance is adhered to; this would give us the documentation in form of source code that I expect to be able to make a reasoned decision about whether or not to support this deprecated feature set. If you would like to engage with this discussion it should go to upstream Linux Kernel Mailing List: https://lore.kernel.org/lkml/[email protected]/ -E
