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. https://community.nxp.com/docs/DOC-105652 File mx6memcal_defconfig configures the board for use with mx6sabresd or mx6qsabreauto.
