This change fixes rv1126, but still fails on rv1103:

$ cat spl/u-boot-spl.map | grep __bss_end
                0x000000000000b468                __bss_end = .
                0x0000000000000050                __bss_size =
(__bss_end - __bss_start)

$ hexdump -Cv spl/u-boot-spl.bin | grep 'd0 0d fe ed'

dtb is correctly found at 0xb468.
