Yes, looks fine to me, except that in VLE mode (do we care?)
".long 0x0fe50553" disassembles as
0: 0f e5 se_cmphl r5,r30
2: 05 53 se_mullw r3,r5
No illegal/trap/privileged insn there.
".long 0x0fe5000b" might be better to cover VLE.

Not without quite a lot of work writing support for that feature.

I think that if CONFIG_MMU is not defined, then ld will remove the
empty section.

er the ELFv2 global entry point
code. If you trash r11 here you're killing the static chain pointer,
used by C nested functions or other languages that use a static chain,
eg. Pascal. r11 has *not* been saved for ELFv2.
r12 might be a better choice for a temp reg.

I just coded this in a similar simple fashion.
It broke building vdso - needs to look into that and will get back when I may
