Subject: tools/nolibc: string: Remove the `_nolibc_memcpy_down()` function
X-Git-Tag: v6.7-rc1~176^2~11

tools/nolibc: string: Remove the `_nolibc_memcpy_down()` function

This nolibc internal function is not used. Delete it. It was probably
supposed to handle memmove(), but today the memmove() has its own
implementation.
