Subject: [PATCH] rt2x00: rt2800lib: move rt2800_drv_data declaration into
rt2800lib.h
The rt2800_drv_data structure contains driver specific
information. Move the declaration into the rt2800lib.h
header which is a more logical place for it. Also fix
the comment style to avoid checkpatch warning.
The patch contains no functional changes, it is in
preparation for the next patch.

Subject: [PATCH] rt2x00: rt2800lib: introduce RT2800_HAS_HIGH_SHARED_MEM flag
Some chipsets have more than 16KB of shared memory.
Introduce a new rt2800 specific flag to indicate that
and add a helper function which helps to check the
presence of the new flag.
Also enable the new flag for the RT3593 chipset which
has 24KB of shared memory. The flag can also be used
for other chipsets, but none of those has been tested
yet.
Signed-off-by: Gabor Juhos <juhosg@openwrt.org>

Changes since v1:
- don't enable the new flag for RT3071 and RT5592

Date: Sat, 17 Aug 2013 19:31:42 +0200
Subject: [PATCH] rt2x00: rt2800: serialize shared memory access
The shared memory of the rt2800 devices is accessible
through the register offset range between 0x4000 and
0x8000. The size of this range is 16KB only and on
devices which have more than 16KB of shared memory either
the low or the high part of the memory is accessible at a
time.
Serialize all accesses to the shared memory by a mutex,
in order to avoid concurrent use of that.

Subject: [PATCH] rt2x00: rt2800lib: fix beacon generation on RT3593
On the RT3593 chipset, the beacon registers are located
in the high 8KB part of the shared memory.
The high part of the shared memory is only accessible
if it is explicitly selected. Add a helper function
in order to be able to control the SHR_MSEL bit in
the PBF_SYS_CTRL register. Also add a few more helper
functions and use those to select the correct part of
the shared memory before and after accessing the beacon
registers.
The base addresses of the beacon registers are also
different from the actually used values, so fix the
'rt2800_hw_beacon_base' function to return the correct
values.

Subject: [PATCH] rt2x00: rt2800lib: add hw_beacon_count field to struct
rt2800_drv_data
Some chipsets can handle more than 8 beacons at once.
Add a new field to the rt2800_drv_data structure which
will hold the number of supported beacons of the given
chipset.
Update the rt2x00_init_registers function to get the
beacon count from the new field instead of using a
hardcoded value.
In order to keep the current behaviour, initialize the
new field with the actually used value.
