not really ... look at the linker scripts and you'll see most do:
.text {
...
common/env_embedded.o (.ppcenv)
...
that's why i didnt use the CONFIG_SYS_USE_PPCENV to figure out how many people
had a dedicated section

can you name a board ? the ones i saw placed the env sector after things,
they didnt split the .text section. otherwise we'd have to do like:
.text.pre.env { ... custom filler ... }
.ppcenv { common/env_embedded.o (.ppcenv) }
.text { ... glob remaining .text }
