mx6: Add board mx6memcal for use in validating DDR
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.

mx6memcal - a tool for calibrating DDR on i.MX6 boards.
|
||||
|
||||
The mx6memcal board isn't a real board, but a tool for use in bring-up of
|
||||
new i.MX6 board designs.
|
||||
|
||||
It provides a similar function to the tool from NXP([1]) with a number
|
||||
of advantages:
|
||||
|
||||
1. It's open-source, so it's easier to change if needed.
|
||||
Typical reasons for needing to change include the use of alternate
|
||||
UARTs and PMIC initialization.
|
||||
2. It produces an image that's directly loadable with imx_usb [2] or
|
||||
SB_LOADER.exe [3].
|
||||
The NXP tool requires either a cumbersome JTAG connection that
|
||||
makes running the DDR very slow or a working U-Boot image that
|
||||
suffers from a chicken-and-egg problem (i.e. where do you get the
|
||||
DDR parameters for U-Boot?).
|
||||
3. It doesn't prompt for parameters, so it's much faster to gather
|
||||
data from multiple boards.
|
||||
4. Parameters to the calibration process can be chosen through
|
||||
'make menuconfig'.
|
||||
|
||||
When booted, the mx6memcal board will run the DDR calibration
|
||||
routines and display the result in a form suitable for cut and
|
||||
paste into struct mx6_mmdc_calibration. It can also optionally
|
||||
produce output in a form usable in a DCD-style .cfg file.
|
||||
|
||||
Selections in Kconfig allow most system design settings to be chosen:
|
||||
|
||||
1. The UART number and pad configuration for the UART. Options
|
||||
include support for the most frequent reference designs on
|
||||
i.MX6DQ/SDL (SABRE Lite and SABRESD designs).
|
||||
2. The memory bus width (64 and 32-bit)
|
||||
3. The number of chip-selects in use
|
||||
4. The type of DDR (DDR3 or LPDDR2). Note that LPDDR2 support
|
||||
is incomplete as of this writing.
|
||||
5. The type of DDR chips in use. This selection allows re-use of common
|
||||
parts and four DDR3 and two LPDDR2 parts are currently defined
|
||||
6. The On-die termination value for the DRAM lines
|
||||
7. The DRAM drive strength
|
||||
8. The RTT_NOM and RTT_WR termination settings
|
||||
9. RALAT/WALAT latency values
