Going from non-FDT to FDT - The changes i made

Hi!

I recently upgraded my Pogoplug V4 with the 3.17-kernel using the DTB-file.

I'm just going to share in short terms the changes i did to the envs under the main installation.
And then also the changes made later for using the DTB-files offcourse (FDT, which could be used with the 3.17-kernel).

The rootfs i used was:
Debian-3.16.0-kirkwood-tld-2-rootfs-bodhi.tar.bz2
U-Boot envs used:
uboot.2014.07-tld-1.environment.img.bodhi.tar
Kernel upgraded using:
linux-3.17.0-kirkwood-tld-1-bodhi.tar.bz2

After writing the U-Boot envs provided by Bodhi, the following changes were made.
"bootcmd_pogo" is for chainloding the original U-Boot which will get you to the original Pogoplug OS (factory) in case USB/SATA/MMC-boot fails.
"preboot" is for enabling netconsole. Nothing new here really.

bootcmd=run bootcmd_usb; run bootcmd_mmc; run bootcmd_sata; run bootcmd_pogo; reset
preboot=run preboot_nc

When upgrading to 3.17, the following commands were executed to make the necessary changes (keeping it clean and simple):

fw_setenv dtbfile '/boot/dts/kirkwood-pogoplug_v4.dtb'
fw_setenv usb_load_dtb 'ext2load usb $device 0x1c00000 $dtbfile'
fw_setenv mmc_load_dtb 'ext2load mmc $device 0x1c00000 $dtbfile'
fw_setenv sata_load_dtb 'ext2load ide $device 0x1c00000 $dtbfile'
fw_setenv usb_boot 'mw 0x800000 0 1; run usb_load_dtb; run usb_load_uimage; if run usb_load_uinitrd; then bootm 0x800000 0x1100000 0x1c00000; else bootm 0x800000 - 0x1c00000; fi'
fw_setenv mmc_boot 'mw 0x800000 0 1; run mmc_load_dtb; run mmc_load_uimage; if run mmc_load_uinitrd; then bootm 0x800000 0x1100000 0x1c00000; else bootm 0x800000 - 0x1c00000; fi'
fw_setenv sata_boot 'mw 0x800000 0 1; run sata_load_dtb; run sata_load_uimage; if run sata_load_uinitrd; then bootm 0x800000 0x1100000 0x1c00000; else bootm 0x800000 - 0x1c00000; fi'

And the final product of course...

This was my way of doing it. Just sharing. :-)

What do you guys think about this? I was bored so i looked into cleaning up the envs above - they should do absoluely the same, just that they've been packaged a bit. Some parts was a bit repetitive...

I appreciate if you could help me spot some error as i'm a noob when it comes to this. :)

NOT TESTED YET!

Can somebody tell me why "bootcmd_mmc" isn't closed with a ";" at the end. I added one here , but i'm not sure if it will brake something... Hm.

John,

It does not matter with or without ; at the end.

Thanks Bodhi! The config above did not work, this one does!
