The dma_memcpy() function takes care of flushing different caches for us. Normally this is what we want, but when resuming from mem, we don't yet have caches enabled. If these functions happen to be placed into L1 mem (which is what we're trying to relocate), then things aren't going to work. So define a non-cache dma_memcpy() variant to utilize in situations like this. Signed-off-by: NMichael Hennerich <michael.hennerich@analog.com> Signed-off-by: NMike Frysinger <vapier@gentoo.org>

Even though the PH8 pin is only internal to the processor packaging, it can be controlled like any other GPIO pin. Now that we have a proper GPIO define, we can fix the SPI0 CS4 define for the internal SPI flash. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

Anomaly 05000491 says that IFLUSH cannot have certain types of memory stalls triggered before it has completed in order to function correctly. One such condition is that it be in L1 instruction. So add a config option to move it there, default it to on, and throw up a warning when it is turned off and this anomaly exists. Since the anomaly should be worked around, we can drop the older method of calling IFLUSH multiple times.

We reserve the 3.75GB - 4GB region of PCIe address space for device to device transfers, making the corresponding physical memory under direct mapping unavailable for DMA. To allow for PCIe DMA to all physical memory we map this chunk of physical memory with BAR1. Because of the resulting discontinuity in the mapping function, we remove a page of memory at each end of the range so multi-page DMA buffers can never be allocated that span the range.

The sixth argument of notify_die() is a signal number, the fifth is a trap number. Instead of passing a signal number in a randomly selected argument, pass it in the sixth. Extract the exception code from regs and pass that as the trap number. Get rid of redundant cast, and remove some gratuitous spaces. Nobody actually does anything with the signal number or trap number, but we might as well populate them with sensible values.
