- 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
