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.
