Subject: [PATCH] brcmfmac: get RAM info right before downloading PCIe firmware

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.
|
|
|
|
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.
