This is v2 of a patch series that adds support for DM to the MPC8XXX SPI
driver, cleans up the driver code, fixes a few minor problems.
Some TODOs are left over for later, such as proper SPI speed setting,
and support for SPI mode setting. These would be enhancements to the
original functionality, and can come later.
The legacy functionality is removed in this version, so old boards in
the tree might end up with broken SPI functionality.

Boards with
- configs/MPC8349EMDS_defconfig
- configs/ids8313_defconfig
are using this driver, so Kim, Heiko please convert enable DM_SPI for the same.
Use below tree for respective changes and update on top of this.

I have a few series in the making that will enable DM on the MPC83xx platform
(I'm doing a respin on the first right now). If there is still interests in the
boards, I could push it to the MPC83xx repository (but mind that the work
required per board is quite extensive).
Also, MPC8349EMDS is de facto abandoned, and I don't have access to the
hardware, so I can't really maintain it.
It's up to you, look like this board maintained by Kim is not
available with freescale e-mail (or may be changed) if none can't
maintain, it better to drop the board.
we use custom 832x boards so please don't remove 83xx from u-boot.
I'm not planning to do that; on the contrary: I'm trying to update the platform
to fully support DM (I hope to get a fully converted board in after the next
release).
The problem is that we only use MPC8308 SoCs, so I can only vouche for the
correctness of that specific SoC. Everything else is a bit up in the air, since
I'm changing code blindly pretty much.
I have a MPC8321 board so I may test it on it if it helps.
In the meantime, I was thinking about using your converted driver and
see if I can adapt it to support MPC8xx as well, instead of converting
the mpc8xx_spi driver to DM, however I've not been able to find your
patches in the master tree allthough they are flagged as accepted in
patchwork.
Are they on another branch somewhere ?
Thanks
Christophe
Best regards,
Mario
