Stefano Babic - Oct. 11, 2012, 7:11 a.m.
The woodburn board is based on the MX35 SOC.
Support for both external (NOR) and internal
(SD Card) boot mode are added. It uses the
generic SPL framework to implement the internal boot
mode.

The following peripherals are supported:
- Ethernet (FEC)
- SD Card
- NAND (512 MB)
- NOR Flash

In the internal boot mode, a simple imximage header
is generated to set the address in internal RAM
where the SOC must copy the SPL code. The initial setup
is then demanded to the SPL itself.

---
Changes in v2:
- fix MX35 boot mode (Eric Benard)
- uses SPL as binary instead of MLO (Thomas Petazzoni, Tom Rini)
- NAND: the harware manufacturer decided for a different chip.  Patches / issues related to NAND are dropped.
- use board_init_f in SPL for setting SDRAM controller

It seems this board uses the old PMIC framework, so it does not merge
properly with u-boot/master which has switched to power in-between. Can
you look into this?

I must say I'm not entirely sure how to handle this, but here is my
proposal: AFAIU this patch was applied initially in your imx tree, so I
suggest that you merge u-boot/master into your tree (with a comment to
the effect that you need this to resolve PMIC vs POWER conflicts) or
into an ad hoc branch, and resolve the conflicts there, then send a
pull request to me for your resolved tree or branch.

Tom, what do you think about this?

Amicalement,

There are conflicts with three boards : mx35pdk, woodburn and mx53loco.

It seems that a couple of patches were lost in the transition from pmic
to power, too:

commit 787f4f30823a15b1e45c0a0b901cfa5bd415e251
Author: Fabio Estevam <fabio.estevam@freescale.com>
Date:   Tue Oct 23 06:36:18 2012 +0000

    pmic: Add support for mc34704

    Add the register layout for the MC34704 PMIC from Freescale.

    Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>

commit 4cfc6c4fa7611e79e6434e97db56b6072ad4d05c
Author: Fabio Estevam <fabio.estevam@freescale.com>
Date:   Tue Oct 23 06:34:50 2012 +0000

    pmic_fsl: Introduce FSL_PMIC_I2C_LENGTH

I solved the conflicts in the way you suggested and I pushed a temporary
branch "master_merge" on u-boot-imx.

I am unsure, too, if this is the best way to solve these conflicts, but
if Tom agrees on our way to proceed, I will post a new pull request.

Best regards,
Stefano

I'm OK with this method now, so long as at the end of the day, git
diff looks good.
