[U-Boot] __bss_end__ and the like

[Simon Glass]

Hi,

grep -rs __bss_end__ * |wc
    215    1011   11552
grep -rs "__bss_end " * |wc
     39     195    2175

I think we should standardise on one or other of these. To me it feels
like __bss_end is correct, since we have __bss_start and none of the
other symbols have a __ at the end.

Comments? If no objections then I will do a patch.

Regards,
