2016-12-15edac: rename edac_core.h to edac_mc.hMauro Carvalho Chehab
Now, all left at edac_core.h are at drivers/edac/edac_mc.c, so rename it to edac_mc.h. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-10-22EDAC, altera: Disable IRQs while injecting SDRAM errorsThor Thayer
Disable IRQs while injecting SDRAM errors. The RT patches exposed a spinlock deadlock where the spinlock taken for the regmap write deadlocked with the IRQ clear regmap write. Error injection is not normally enabled for ECC but only for testing.

In preparation for additional memory module ECCs, the IRQ function will check a panic flag before doing a kernel panic on double bit errors. OCRAM uncorrectable errors cause a panic because sleep/resume functions and FPGA contents during sleep are stored in OCRAM. ECCs on peripheral FIFO buffers will not cause a kernel panic on DBERRs because the packet can be retried and therefore recovered.

Suspend-to-RAM and EDAC support are mutually exclusive on SOCFPGA. If EDAC is enabled, it will prevent the platform from going into suspend. The reason is that the IRQ vectors for OCRAM reside on DDR and in Suspend-to-RAM mode we're executing out of OCRAM.
