Subject: [PATCH] barebox in-system update infrastructure
Date: Mon, 15 Oct 2012 15:15:03 +0200	[thread overview]
Message-ID: <1350306908-25206-1-git-send-email-s.hauer@pengutronix.de> (raw)

This is an update to the barebox in-system update infrastructure
I posted some time ago.

Basically this infrastructure adds a command which calls previously
registered handlers to update barebox in flash/mmc/...

Here is an example session:

barebox@Ka-Ro tx53:/ barebox_update
Usage: barebox_update [OPTIONS] <image>
Update barebox to persistent media
-t <target>
-d <device>     write image to <device> instead of handler default
                Can be used for debugging purposes (-d /tmpfile)
-y              yes. Do not ask for confirmation
-f <level>      Set force level
-l              list registered targets

barebox@Ka-Ro tx53:/ barebox_update -l
registered update handlers:
* nand-xx30   -> /dev/nand0
  mmc-1011    -> /dev/disk0

barebox@Ka-Ro tx53:/ barebox_update -t mmc-1011 /mnt/tftp/barebox-tx53.bin
100Mbps full duplex link detected
DHCP client bound to address 192.168.24.6
update barebox from /mnt/tftp/barebox-tx53.bin using handler mmc-1011 to /dev/disk0 (y/n)?
updating to /dev/disk0
update succeeded

The only user of this infrastructure currently is the i.MX internal
boot mode. For MMC/SD users this has the advantage that the update
command preserves the partition table on the MMC/SD card. For NAND
users it has the advantage that a BBT table for the i.MX BOOT ROM is
created, so that bad blocks in the area where the barebox binary
resides are automatically skipped. Also before flashing an image
it's tested whether the image to flash really is a barebox image.
