According to doc/README.distro fdt_addr must not be set when DTB is not available from hardware. So remove this entry.
Use address 32MB above the start of DRAM for kernel_addr_r. This way we likely can avoid the self-relocation of the compressed kernel image before it decompresses to offset 0x8000 from start of DRAM. Use address 128MB above the start of DRAM for fdt_addr_r, since this is the maximum location for the end of the kernel. So we avoid overwriting the DTB. Use 512k above that for ramdisk_addr_r. This should be enough for the DTB, rest of DRAM can be used for initrd. Place boot script / extlinux.conf at offset 0 / 1MB from start of DRAM. This space is available for processing in U-Boot.

Distroboot support for the tbs2910 board was added in the v2020.10 merge window. So please pull this in as fix for v2020.10.
