net: cpsw: prevent stray cache writeback ...

The cache should be invalidated when transfering ownership of a buffer
to the device. Otherwise the writeback of dirty cache lines can
corrupt the hardware written data.

mtd: nand-bb: Fix accesses beyond device ...

When a block is marked bad after the bb device has been created
the real size of the bb device is smaller than the calculated size
on creation. In this case we can't rely on the upper layers anymore
that they won't pass read/write sizes in that fit into the device.

|     mtd: omap gpmc: fix ecc bytes/size
|
|     The ecc bytes / size are per subpage, not per page.
|
|     Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

The ecc code in omap_correct_data() expects to correct a whole page
at once, so we must tell the nand layer that we have 4 * 13 bytes of
ecc bytes and 4 * 512 bytes of ecc size. Otherwise the NAND layer will
iterate over 512 byte steps over a page and call the .correct callback
each time.

This only works for 2k pagesize and needs revisit once other page sizes
shall be supported. It would be better to tell the nand layer the real
ecc bytes (13) and ecc size (512) instead and drop the iteration in
omap_correct_bch(). However, this needs better testing so it isn't done
here now.

net: smc1111: extend the driver for 91c94 and 91c96 support ...

All the smcs family chips 91c94, 91c96, 91c100, 91c111 share almost the
same behavior and register sets. The noticeable exceptions are coped
with in this patch, ie :
 - 91c94 and 91c96 only have an internal 10 Mbps phy
   The registers used for phy discovery on later chips will corrupt the
   91c96 state.
 - 91c94 and 91c96 have a control and config register quite different
   from their 91c1xx conterparts
   A platform data user defined couple of registers is introduced. If
   these values are 0, 91c1xx legacy behavior is assumed.

net: smc1111: add 16 bits accessors, allow address shift ...

Smc network IPs can be wired up in different funny ways. For example the
lubbock pxa25x development platform wires all address lines shifted by
2, ie. bus A2 is smc91c96 A0, bus A3 is smc91c96 A1 etc ...

In order to cope with the different possible combination, add a shift
parameter for addresses.

By default, the old behaviour using the 32 bit accesses is kept.
