Context 0 (which handles the error packets) can potentially receive an invalid
rhf. Hence, it can not depend on RHF sequence number and can only use DMA_RTAIL
mechanism. Detect such packets with invalid rhf using rhf sequence counting
mechanism and drop them.
As DMA_RTAIL mechanism has performance penalties, do not use context 0 for
performance critical verbs path. Use context 0 for VL15 (MAD), multicast and
error packets.

Commit 4316302292 ("mtd: m25p80: allow arbitrary OF matching for
"jedec,spi-nor"") moved the "jedec,spi-nor" handling from the
spi_device_id table to the of_match_table, to better handle matching
complex device tree compatible strings. With that patch, device tree
support works as expected when m25p80.c is built into the kernel.
However, that commit ignored the fact that:
(1) (non-DT) platform devices might want to use the "spi-nor" string
for matching with this driver, rather than picking an arbitrary one
like "m25p80"
(2) the core SPI uevent/modalias code doesn't yet support kernel module
autoloading via of_match_table strings; so for DT-based devices, it
will only report (part of) the first compatible string used
Problem (1) has been reported previously, and I forgot to patch it up
afterward.
Problem (2) was noticed recently here:
http://lists.infradead.org/pipermail/linux-mtd/2015-October/062369.htmlhttps://lkml.org/lkml/2015/11/12/574
Specifically, this patch fixes m25p80.ko module autoloading for cases
like this:
flash@xxx {
compatible = "jedec,spi-nor";
...
};
because modalias of "spi:spi-nor" (the only module loading info provided
by the SPI core for this device) will now be listed as an alias in
m25p80.ko.
Notably, it does *not* help cases like this:
flash@xxx {
compatible = "vendor,shiny-new-device", "jedec,spi-nor";
...
};
unless we also list "shiny-new-device" in m25p_ids[]. There has been
discussion on future work for this issue here:
