+Subject: [PATCH] brcmfmac: get chip's default RAM info during PCIe setup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
-It's important as brcmf_chip_get_raminfo() also makes sure that memory
-is properly setup. Without it the firmware could report invalid RAM
-address like 0x04000001.
+Getting RAM info just once per driver's lifetime (during chip
+recognition) is not enough as it may get adjusted later (depending on
+the used firmware). Subsequent inits may load different firmwares so a
+full RAM recognition is required on every PCIe setup. This is especially
+important since implementing hardware reset on a firmware crash.
-During a normal brcmfmac lifetime brcmf_chip_get_raminfo() is called on
-probe by the brcmf_chip_recognition(). This change allows implementing
-further improvements like handling errors by resetting a device with
-the brcmf_pcie_reset_device() and redownloading a firmware afterwards.
+Moreover calling brcmf_chip_get_raminfo() makes sure that RAM core is
+up. It's important as having BCMA_CORE_SYS_MEM down on BCM4366 was
+resulting in firmware failing to initialize and following error:
+[ 65.657546] brcmfmac 0000:01:00.0: brcmf_pcie_download_fw_nvram: Invalid shared RAM address 0x04000001
+This change makes brcmf_chip_get_raminfo() call during chip recognition
+redundant for PCIe devices but SDIO and USB still need it and it's a
+very small overhead anyway.
+
+Fixes: 4684997d9eea ("brcmfmac: reset PCIe bus on a firmware crash")
