Series | [1/3,v2] riscv: Remove OF_PRIOR_STAGE from RISC-V boards | expand |
Please ignore this. I just noticed it will probably not work for ax25-ae350, since it will try to load a DTB from u-boot binary. I'll send a v3 shortly fixing this Regards /Ilias On Thu, 30 Sept 2021 at 09:41, Ilias Apalodimas <ilias.apalodimas@linaro.org> wrote: > > At some point back in 2018 prior_stage_fdt_address and OF_PRIOR_STAGE got > introduced, in order to support a DTB handed over by an earlier stage boo > loader.
