+From a7f268af31dddf763fe3dbe9cbf96ea77e0540e0 Mon Sep 17 00:00:00 2001

+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
