+* Aspeed Firmware Memory controller
+* Aspeed SPI Flash Memory Controller
+
+The Firmware Memory Controller in the Aspeed AST2500 SoC supports
+three chip selects, two of which are always of SPI type and the third
+can be SPI or NOR type flash. These bindings only describe SPI.
+
+The two SPI flash memory controllers in the AST2500 each support two
+chip selects.
+
+Required properties:
+ - compatible : Should be one of
+ "aspeed,ast2400-fmc" for the AST2400 Firmware Memory Controller
+ "aspeed,ast2400-spi" for the AST2400 SPI Flash memory Controller
+ "aspeed,ast2500-fmc" for the AST2500 Firmware Memory Controller
+ "aspeed,ast2500-spi" for the AST2500 SPI flash memory controllers
+
+ - reg : the first contains the control register location and length,
+ the second contains the memory window mapping address and length
+ - #address-cells : must be 1 corresponding to chip select child binding
+ - #size-cells : must be 0 corresponding to chip select child binding
+
+Optional properties:
+ - interrupts : Should contain the interrupt for the dma device if an
+ FMC
+
+The child nodes are the SPI flash modules which must have a compatible
+property as specified in bindings/mtd/jedec,spi-nor.txt
+
+Optionally, the child node can contain properties for SPI mode (may be
+ignored):
+ - spi-max-frequency - max frequency of spi bus
+
+
+Example:
+fmc: fmc@1e620000 {
+ compatible = "aspeed,ast2500-fmc";
+ reg = < 0x1e620000 0x94
+ 0x20000000 0x02000000 >;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ interrupts = <19>;
+ flash@0 {
+ reg = < 0 >;
+ compatible = "jedec,spi-nor";
+ /* spi-max-frequency = <>; */
+ /* m25p,fast-read; */
+ #address-cells = <1>;
+ #size-cells = <1>;
+ };
+};

+Upgrading BIOS using intel-spi
+------------------------------
+
+Many Intel CPUs like Baytrail and Braswell include SPI serial flash host
+controller which is used to hold BIOS and other platform specific data.
+Since contents of the SPI serial flash is crucial for machine to function,
+it is typically protected by different hardware protection mechanisms to
+avoid accidental (or on purpose) overwrite of the content.
+
+Not all manufacturers protect the SPI serial flash, mainly because it
+allows upgrading the BIOS image directly from an OS.
+
+The intel-spi driver makes it possible to read and write the SPI serial
+flash, if certain protection bits are not set and locked. If it finds
+any of them set, the whole MTD device is made read-only to prevent
+partial overwrites. By default the driver exposes SPI serial flash
+contents as read-only but it can be changed from kernel command line,
+passing "intel-spi.writeable=1".
+
+Please keep in mind that overwriting the BIOS image on SPI serial flash
+might render the machine unbootable and requires special equipment like
+Dediprog to revive. You have been warned!
+
+Below are the steps how to upgrade MinnowBoard MAX BIOS directly from
+Linux.
+
+ 1) Download and extract the latest Minnowboard MAX BIOS SPI image
+ [1]. At the time writing this the latest image is v92.
+
+ 2) Install mtd-utils package [2]. We need this in order to erase the SPI
+ serial flash. Distros like Debian and Fedora have this prepackaged with
+ name "mtd-utils".
+
+ 3) Add "intel-spi.writeable=1" to the kernel command line and reboot
+ the board (you can also reload the driver passing "writeable=1" as
+ module parameter to modprobe).
+
+ 4) Once the board is up and running again, find the right MTD partition
+ (it is named as "BIOS"):
+
+ # cat /proc/mtd
+ dev: size erasesize name
+ mtd0: 00800000 00001000 "BIOS"
+
+ So here it will be /dev/mtd0 but it may vary.
+
+ 5) Make backup of the existing image first:
+
+ # dd if=/dev/mtd0ro of=bios.bak
+ 16384+0 records in
+ 16384+0 records out
+ 8388608 bytes (8.4 MB) copied, 10.0269 s, 837 kB/s
+
+ 6) Verify the backup
+
+ # sha1sum /dev/mtd0ro bios.bak
+ fdbb011920572ca6c991377c4b418a0502668b73 /dev/mtd0ro
+ fdbb011920572ca6c991377c4b418a0502668b73 bios.bak
+
+ The SHA1 sums must match. Otherwise do not continue any further!
+
+ 7) Erase the SPI serial flash. After this step, do not reboot the
+ board! Otherwise it will not start anymore.
+
+ # flash_erase /dev/mtd0 0 0
+ Erasing 4 Kibyte @ 7ff000 -- 100 % complete
+
+ 8) Once completed without errors you can write the new BIOS image:
+
+ # dd if=MNW2MAX1.X64.0092.R01.1605221712.bin of=/dev/mtd0
+
+ 9) Verify that the new content of the SPI serial flash matches the new
+ BIOS image:
+
+ # sha1sum /dev/mtd0ro MNW2MAX1.X64.0092.R01.1605221712.bin
+ 9b4df9e4be2057fceec3a5529ec3d950836c87a2 /dev/mtd0ro
+ 9b4df9e4be2057fceec3a5529ec3d950836c87a2 MNW2MAX1.X64.0092.R01.1605221712.bin
+
+ The SHA1 sums should match.
+
+ 10) Now you can reboot your board and observe the new BIOS starting up
+ properly.
