[U-Boot] FDT placement in OpenSBI + U-Boot + Linux kernel issue for RISC-V

Hi All, I noticed following issues around U-Boot fdt location in Unleashed and Qemu virt machine. OpenSBI copies the FDT to following addresses for respective platforms Qemu: 0x8220 Unleashed: 0x8800 As CONFIG_PRIOR_STAGE is set for both platforms, fdt is first copied to

to fdt_addr_r 2. setenv fdt_addr $fdt_addr_r In this way, U-Boot will not have any direct dependancies on OpenSBI. As long as U-Boot is configured with a fdt_addr_r, it should work. It will be still valid for loading fdt from tftp server to fdt_addr_r as well. > * Scenario 3: fdt blob i
