hm, I can't reproduce that:
$ qemu-system-mips -M malta -cpu 24Kc -m 256 -nographic -drive if=pflash,file=/work/u-boot-mips/pflash.bin,format=raw -netdev user,id=ubtest,tftp=/work/u-boot-mips -device pcnet,netdev=ubtest
malta # md BE040000 4
be040000: ffffffff ffffffff ffffffff ffffffff ................
malta # erase BE040000 +10000
. done
Erased 1 sectors
malta # md BE040000 4
be040000: ffffffff ffffffff ffffffff ffffffff ................
and saveenv works for me too:
