Hello,
I get the newest kernel from
git clone git://newgolddream.dyndns.info/
because I hoped to get rid of my problems, when I activate the cache
on my SH7750R based board.
When I compiled it without Cache (CONFIG_CACHE_OFF activated):
I get the following error:
UPD include/linux/compile.h
CC init/version.o
LD init/built-in.o

DECLARE_EXPORT(__movstr_i4_even);
and it compiles clean (with CONFIG_CACHE_WRITETHROUGH=y)...
but I am not sure if this is correct.
I use gcc:

Nevertheless, with caches activated, Linux doesnt boot ... I am
