actually no boards use the default lowlevel_init.S
so remove it

btw the u-boot.lds is not anymore need to be generated

I understand this patch is supposed to fix the bug introduced by
commit f0a2c7b4b64eacd0?

You should note this in the message.

Best regards,

Wolfgang Denk

at the same time but it's a side effect

I just notice that noone use the default lowlevel_init.S

which force the norflash boot to add an entry in the lds to force the weak
function overwrite so I fix this

Best Regards,
J.

This patch may be fixing the out-of-tree build problem introduced
with commit f0a2c7b4 "at91: add support for the PM9263 board", but it
causes a LOT of new issues:
