[U-Boot] Probing flash before Env setup (Env in UBI)

[Dominik Vogt]

Hi folks,

I'm new to uboot and couldn't figure out how to get
"CONFIG_ENV_IS_IN_UBI" to work (on a nor flash) yet.

Basically, ubi and ubifs work fine.  The mtd device (a nor flash)
is supported and works.  It is formatted with ubiformat and
contains two volumes with a ubifs on each of them.

The "partition" is named "nor0" and the volumes are "env-uboot"
and "env-uboot-redund".

Now, when the board boots, it tries to load the envorinment and
fails:

-- snip --
  Loading Environment from SPI Flash... SF: Detected n25q128 with page size 256 Bytes, erase size 64 KiB, total 16 MiB
  *** Warning - bad CRC, using default environment

  Loading Environment from UBI... Partition nor0 not found!

  ** Cannot find mtd partition "nor0"
-- snip --

The first line looks like the output from "sf probe", but "mtd
list" just says:

  List of MTD devices:
  No MTD device found

Well, I guess I just have to run

  sf probe
  ubi part nor0

before loading he environment, but I couldn't figure out how to do
that, except by adding some C code to board_init_f().

Ciao
