This is a virtual "board" that uses configuration files and
Kconfig to define the memory layout used by a real board during
the board bring-up process.
It generates an SPL image that can be loaded using imx_usb or
SB_LOADER.exe.
When run, it will generate a set of calibration constants for
use in either or both a DCD configuration file for boards that
use u-boot.imx or struct mx6_mmdc_calibration for boards that
boot via SPL.
In essence, it is a configurable, open-source variant of the
Freescale ddr-stress tool.

File mx6memcal_defconfig configures the board for use with
mx6sabresd or mx6qsabreauto.
Do you still have plans on refreshing this series?
Plans is a strong word, but I certainly hope to find some time
to continue this effort.
I haven't been doing too many new board bring-ups lately though,
so it moved away from my front burner.
I set this aside because I wasn't able to get the "return to
RBL" code working and figured I'd try to reverse-engineer the API.
Any hints you have in that area would be helpful, and will solve
that other long-standing issue of how to live with SPL on i.MX.
It does seem very useful.
It is, and even the RFC patch allows very quick testing of
large numbers of boards to gather calibration data.
Regards,
Eric
