+Subject: [PATCH] brcmfmac: support NVRAMs containing pci devpaths (instead of
+ pcie)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Recently Broadcom added support for NVRAMs with entries for multiple
+PCIe devices. One of the supported formats is based on prefixes defined
+like: devpath0=pcie/1/4/ and entries like 0:foo=bar 0:baz=qux etc.
+
+Unfortunately there are also a bit older devices using different way of
+defining prefixes, e.g. SmartRG SR400ac (2 x BCM43602) with entries:
+devpath0=pci/1/1/
+devpath1=pci/2/1
+Broadcom stated this old format will never be used/supported by brcmfmac
+but given the simplicity of this patch I'll insist on supporting it.

+Subject: [PATCH] brcmfmac: use direct data pointer in NVRAM parser struct
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+As we plan to add support for platform NVRAM we should store direct
+data pointer without the extra struct firmware layer. This will allow
+us to support other sources with the only requirement being u8 buffer.
