Builds the spi-nor.img together with the sdcard.img.
Readme is extended with SPI NOR flash writing instructions
and recovery.

The spi-nor.img layout is based on the following document:

  Applied to master, thanks.

  I've added the following paragraph to the readme:

Note that Buildroot puts the bootloader both in SPI NOR and on the SD card,
so after flashing as instructed above, either boot mode should work.

  If this is not correct, could you please send a correction?

  Regards,
  Arnout
