[flashrom] ASRock AM2NF6G-VSTA (Nvidia MCP61): `flashrom -Vr` (r1483)

[Paul Menzel]

Dear Flashrom folks,


I tested the ASRock AM2NF6G-VSTA with an Nvidia MCP61 chipset. The
output says, that the chipset is not fully supported so please tell me
what I have to consider when testing writing.

        $ flashrom -V -r am2nf6g-vsta.bin
        […]
        DMI string system-manufacturer: "To Be Filled By O.E.M."
        DMI string system-product-name: "To Be Filled By O.E.M."
        DMI string system-version: "To Be Filled By O.E.M."
        DMI string baseboard-manufacturer: "                      "
        DMI string baseboard-product-name: "AM2NF6G-VSTA"
        DMI string baseboard-version: "                      "
        DMI string chassis-type: "Desktop"
        Found chipset "NVIDIA MCP61" with PCI ID 10de:03e0. 
        This chipset is marked as untested. If you are using an up-to-date version
        of flashrom please email a report to flashrom at flashrom.org including a
        verbose (-V) log. Thank you!
        Enabling flash write... This chipset is not really supported yet. Guesswork...
        ISA/LPC bridge reg 0x8a contents: 0x00, bit 6 is 0, bit 5 is 0
        Flash bus type is LPC
        Found SMBus device 10de:03eb at 00:01:1
        MCP SPI BAR is at 0x40000000
        Strange. MCP SPI BAR is valid, but chipset apparently doesn't have SPI enabled.
        Please send the output of "flashrom -V" to flashrom at flashrom.org with
        your board name: flashrom -V as the subject to help us finish support for your
        chipset. Thanks.
        OK.
        The following protocols are supported: LPC.

Reading seems to work. The difference between the read image to the
downloaded file (1.20) from the ASRock [2] is minimal according to
`bsdiff`.
