* ARM: OMAP: GPIO: IRQSTATUS2 workaround for retention stateHiroshi DOYU2006-09-251-0/+6
| | | | | | | | | | | | | In OMAP2420, an incoming GPIO interrupt always sets both GPIO_IRQSTATUS1 and GPIO_IRQSTATUS2, even if the relevant bit is disabled in GPIO_IRQENABLE1/2 and DSP doesn't use GPIO at all. GPIO_IRQSTATUS1 is for MPU and GPIO_IRQSTATUS2 is for DSP. If IRQSTATUS is set, this will prevent the system from going to idle state. This patch also clears IRQSTATUS2 to avoid the above situation.

* [ARM] 3762/1: Fix ptrace cache coherency bug for ARM1136 VIPT nonaliasing ↵George G. Davis2006-09-021-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Harvard caches Patch from George G. Davis Resolve ARM1136 VIPT non-aliasing cache coherency issues observed when using ptrace to set breakpoints and cleanup copy_{to,from}_user_page() while we're here as requested by Russell King because "it's also far too heavy on non-v6 CPUs". NOTES: 1. Only access_process_vm() calls copy_{to,from}_user_page(). 2. access_process_vm() calls get_user_pages() to pin down the "page". 3. get_user_pages() calls flush_dcache_page(page) which ensures cache coherency between kernel and userspace mappings of "page". However flush_dcache_page(page) may not invalidate I-Cache over this range for all cases, specifically, I-Cache is not invalidated for the VIPT non-aliasing case. So memory is consistent between kernel and user space mappings of "page" but I-Cache may still be hot over this range. IOW, we don't have to worry about flush_cache_page() before memcpy(). 4. Now, for the copy_to_user_page() case, after memcpy(), we must flush the caches so memory is consistent with kernel cache entries and invalidate the I-Cache if this mm region is executable. We don't need to do anything after memcpy() for the copy_from_user_page() case since kernel cache entries will be invalidated via the same process above if we access "page" again. The flush_ptrace_access() function (borrowed from SPARC64 implementation) is added to handle cache flushing after memcpy() for the copy_to_user_page() case. Signed-off-by: George G.

The ds1307 is used to initialize the system time, since it's battery-backed. From then on the AT91 RTC is used, since it's more capable (with both alarm and update irqs, and system wakeup capability) even though it needs manual initialization (symlink /dev/rtc to /dev/rtc0 for older versions of hwclock, then "hwclock --systohc") in an rc script or from inittab.
