+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.

+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.

+ 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.
