Testing recent mainline git head for omap3_evm_config I get compiler 
warning

env_onenand.c: In function 'saveenv':
env_onenand.c:104: warning: format '%08lx' expects type 'long unsigned 
int', but argument 2 has type 'loff_t'

Is there already a fix available?

Thanks

Dirk

Since env_addr is a loff_t (long long), "%08lx" is not a good format;
this uses "%08llx" (not "%016llx"), to get 8 or more hex digits.  I
tnknk padding to 8 digits makes things more readable for "small"
numbers, and the unlikely values over 4GB are reported correctly
anyways.

I found this during "./MAKEALL arm", and it affects my nhk8815 as
well.  The warning was already reported today by Dirk Behme, thus this is
reply to his message.

But %llx needs CONFIG_SYS_64BIT_VSPRINTF - are we sure that this is
#define'd on all boards that use onenand?

Best regards,
