Julius Werner	1143d08f7e	libpayload: head.S: Avoid clearing BSS (and heap) again 3 out of 4 architectures currently zero out the payload BSS in early assembly code, which is pointless since the code loading the payload has already done that (with a more efficient memset). ARM64 has never had any code like this and can run just fine without it. This also defeats the new optimization of moving the heap out of the BSS, since all three implementations assume that everything between _edata and _end is BSS. We should just take this out.

libpayload: head.S: Avoid clearing BSS (and heap) again

3 out of 4 architectures currently zero out the payload BSS in early
assembly code, which is pointless since the code loading the payload has
already done that (with a more efficient memset). ARM64 has never had
any code like this and can run just fine without it. This also defeats
the new optimization of moving the heap out of the BSS, since all three
implementations assume that everything between _edata and _end is BSS.
We should just take this out.
