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. - -Signed-off-by: Gabor Juhos <juhosg@openwrt.org> ---- -Changes since v1: --- ---- - drivers/net/wireless/ralink/rt2x00/rt2800.h | 3 +++ - drivers/net/wireless/ralink/rt2x00/rt2800lib.c | 44 +++++++++++++++++++++++++++++++ - 2 files changed, 47 insertions(+) - ---- a/drivers/net/wireless/ralink/rt2x00/rt2800.h -+++ b/drivers/net/wireless/ralink/rt2x00/rt2800.h -@@ -574,6 +574,7 @@ - #define PBF_SYS_CTRL 0x0400 - #define PBF_SYS_CTRL_READY FIELD32(0x00000080) - #define PBF_SYS_CTRL_HOST_RAM_WRITE FIELD32(0x00010000) -+#define PBF_SYS_CTRL_SHR_MSEL FIELD32(0x00080000) - - /* - * HOST-MCU shared memory -@@ -2026,6 +2027,8 @@ struct mac_iveiv_entry { - (((__index) < 6) ?
