           Summary: dynamic mtd partition table cration
           Product: OpenMoko
           Version: current svn head
          Platform: GTA01
        OS/Version: Linux
            Status: NEW
          Severity: blocker
          Priority: P2
         Component: u-boot
        AssignedTo: laforge at openmoko.org
        ReportedBy: laforge at openmoko.org

When the device boots the first time, u-boot does a NAND bad block scan, and
stores the result in the bbt (bad block table) at the end of flash.  At this
point we know at which locations the factory-default-bad-blocks are, and can
thus determine at which page offsets the individual partitions start.  this
information is stored in the environment, from which it generates a bootcmd
paramter that tells the kernel about the device-specific mtd partition table.
