Subject: [PATCH] brcmfmac: add credit numbers updating support
The credit numbers are static and tunable per chip in firmware side.
However the credit number may be changed that is based on packet pool
length and will send BRCMF_E_FIFO_CREDIT_MAP event to notify host driver
updates the credit numbers during interface up.
The purpose of this patch is making host driver has ability of updating
the credit numbers when receiving the BRCMF_E_FIFO_CREDIT_MAP event.

Subject: [PATCH] brcmfmac: enable frameburst mode in default firmware setting
The frameburst feature can enable per-packet framebursting in firmware
side and get higher TX throughput in High Throughput(HT) mode. To enhance
TX throughput, we enable frameburst mode in default firmware setting.

Subject: [PATCH] brcmfmac: set SDIO F1 MesBusyCtrl for CYW4373
Along with F2 watermark (existing) configuration, F1 MesBusyCtrl
should be enabled & sdio device RX FIFO watermark should be
configured to avoid overflow errors.

GCI core is needed for ULP operation. Allow GCI core enumuration with
below changes:
- Allow GCI to be added to core list even when it doesn't have a wrapper.
- Allow 8K address space size.
- Don't overwrite the address value when an additional size descriptor
is in place.

Subject: [PATCH] brcmfmac: update 43012 F2 watermark setting to fix DMA Error
during UDP RX Traffic
The number of words that the read FIFO has to contain except
the end of frame before sends data back to the host.
Max watermark = (512B - 2* (BurstLength))/4 =
(512 - 128)/4 = 384/4 = 0x60
so if burst length (i.e. BurstLength = 64) is increased,
watermark has to be reduced. This is the optimal setting for this chip.

Subject: [PATCH] brcmfmac: disable command decode in sdio_aos
AOS is a part of the SDIOD core that becomes active when the rest of
SDIOD is sleeping to keep SDIO bus alive responding to reduced set of
commands.
Transaction between AOS and SDIOD is not protected, and if cmd 52 is
received in AOS and in the middle of response state changed from AOS to
SDIOD, response is corrupted and it causes to SDIO Host controller to
hang.
Command decode for below chips are disabled in this commit:

Subject: [PATCH] brcmfmac: fix false-positive -Wmaybe-unintialized warning
When CONFIG_NO_AUTO_INLINE is set, we get a false-postive warning
for the brcmf_fw_request_nvram_done() function, after gcc figures
out that brcmf_fw_nvram_from_efi() might not set the 'data_len'
variable, but fails to notice that it always returns NULL:
drivers/net/wireless/broadcom/brcm80211/brcmfmac/firmware.c: In function 'brcmf_fw_request_nvram_done':
drivers/net/wireless/broadcom/brcm80211/brcmfmac/firmware.c:560:11: error: 'data_len' may be used uninitialized in this function [-Werror=maybe-uninitialized]
Mark it 'inline' to force gcc to understand this.

Subject: [PATCH] brcmfmac: Fix access point mode
Since commit 1204aa17f3b4 ("brcmfmac: set WIPHY_FLAG_HAVE_AP_SME flag")
the Raspberry Pi 3 A+ (BCM43455) isn't able to operate in AP mode with
hostapd (device_ap_sme=1 use_monitor=0):
brcmfmac: brcmf_cfg80211_stop_ap: setting AP mode failed -52
So add the missing mgmt_stypes for AP mode to fix this.
