add boot command support to Snowball

I have an MP in place to help silence some dumb warnings this config change will cause.

Fathi - the main thing I need to know is what you want the actual boot commands for the FDT scenario to be?

Latest snowball images have uinitrd, the boot commands should look like below:
boot_cmds = mmc init,
mmc rescan 1,
setenv bootcmd "'fat load mmc 1:3 0x00100000 /uImage; fat load mmc 1:3 0x01000000 /uInitrd; bootm 0x00100000 0x01000000'"
setenv bootargs "'console=ttyAMA2,115200n8 root=/dev/mmcblk1p5 rootwait ro fixrtc nocompcache vmalloc=300M mem=128M@0 mali.mali_mem=32M@128M hwmem=168M@160M mem=48M@328M mem_issw=1M@383M mem=640M@384M'",
boot

Andrey is looking into enabling DT, I let him follow up with the right boot commands.

boot commands with uInitrd and dtb:
boot_cmds = mmc init,
mmc rescan 1,
setenv bootcmd "'fat load mmc 1:3 0x00100000 /uImage; fat load mmc 1:3 0x01000000 /uInitrd; fat load mmc 1:3 0x00f00000 /board.dtb; bootm 0x00100000 0x01000000 0x00f00000'"
setenv bootargs "'console=ttyAMA2,115200n8 root=/dev/mmcblk1p5 rootwait ro fixrtc nocompcache vmalloc=300M mem=128M@0 mali.mali_mem=32M@128M hwmem=168M@160M mem=48M@328M mem_issw=1M@383M mem=640M@384M'",
boot

I've checked this into our salt repo first. So we can test it some before adding to lava-dispatcher permanently.

Should be able to use this with a boot action like:

{
          "command": "boot_linaro_image",
   "parameters": {
    "options": ["boot_cmds=boot_cmds_fdt"]
   }
    },

good news - I'm probably just dumb and created the wrong device-config. I'm testing something in staging now, and can probably roll out a fix very soon.

a "fix" has been deployed. I've re-submitted the job here:

  http://validation.linaro.org/lava-server/scheduler/job/46374

ugh - didn't work. let me actually do some debugging

this reuired a code change so we didn't break android:

https://code.launchpad.net/~doanac/lava-dispatcher/boot-cmds/+merge/145282

I've tried this job which sets "options": ["boot_cmds=boot_cmds_fdt"] :
http://validation.linaro.org/lava-server/scheduler/job/46482/definition

According to the log, LAVA doesn't seem to handle this boot_cmds setting:
http://validation.linaro.org/lava-server/scheduler/job/46482/log_file#entry14
"<LAVA_DISPATCHER>2013-01-29 04:19:10 PM WARNING: Invalid boot option: boot_cmds"

Also the U-Boot 2009.11 is not good for booting with DT. Only U-Boot 2013.01 (it seems to be the latest one) is able to pass the dtb to the kernel.

The fix has been "committed", not "released". I'm hoping to deploy in a
few hours. When its done, I'll personally verify this is working before
asking you guys to try this again.

This is unfortunate. When I first asked, I was told this u-boot was
sufficient. Changing u-boot for snowballs will be a non-trivial amount
of work. We'll need to identify a release with this, create a master
image in the lab, and run a large number of tests against this to ensure
it will serve as a stable master image.

Fathi - probably should create a BP for this if its the case.

The u-boot issue isn't new, Andrey raised it each time we discussed the topic...
In addition, it has been raised mid-december with http://bazaar.launchpad.net/~fboudra/lava-dispatcher/load-uinitrd-ubuntu/revision/506

the whole master image story and hardcoded boot commands is a mess :(
