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.
