This partial V2 completes the previous partial V2. It contains some final preparational steps, and the introduction of cm-fx6 board.
Changes in V2: - Update commit message of "arm: mx6: ddr: configure MMDC for slow_pd" - Remove unnecessary line removal from arch/arm/cpu/armv7/mx6/ddr.c - Move probe_mmdc_config() code straight to dram_init() - Use imx6_spl.h - Use imx_ddr_size() NOTE: the correction of this patch now depends on https://patchwork.ozlabs.org/patch/376095/
Does this series support the dual core Utilite machine?
It does support dual core, but not the Utilite boot sequence. Right now you can only boot from MMC because SPL has no fallback functionality and Utilite always tries MMC first. I'll be sending patches for that after this series is accepted.
If so I'm not sure how to enable dual core instead of quad core - any ideas please?
You don't need to do anything to run this on dual core. ...or am I misunderstanding your question?
I'm not sure. It was failing to boot from SD and I thought that might be the problems, since I see quite a few CPU-related configs in the board config file. Is there a canonical description of how to making a boot image and put it on SD? Perhaps I was doing that incorrectly.
You can use the article from the Compulab wiki:

This article assumes that both SPL and U-Boot reside on a single binary at the right offsets. The following article describes the steps for creating this joined image:

Thanks, that works. Somehow I didn't have the two sets of instructions in one place. I have a few comments on the patches which I will send separately.
