That's why my board wasn't booting anymore after your patchset.
if .init is NULL, then in arch/arm/mach-at91/soc.h :
static inline int at91_soc_is_enabled(void)
{
return at91_boot_soc.init != NULL;
}
is false, and in arch/arm/mach-at91/setup.c:
void __init at91_map_io(void)
{
...
if (!at91_soc_is_enabled())
panic("AT91: Soc not enabled");
...
}
Regars,
Richard.
