This patch provides the code to calibrate the DDR's DQS to DQ signals (RDLVL). It is based on: VFxxx Controller Reference Manual, Rev. 0, 10/2016, page 1600 10.1.6.16.4.1 "Software Read Leveling in MC Evaluation Mode" and NXP's community thread: "Vybrid: About DDR leveling feature on DDRMC." https://community.nxp.com/thread/395323 Signed-off-by: Lukasz Majewski <lukma@denx.de>

This enables the 'bmode' (bootmode) command for forcing
|
|
a boot from specific media.
|
|
|
|
This is useful for forcing the ROM's usb downloader to
|
|
activate upon a watchdog reset which is nice when iterating
|
|
on U-Boot. Using the reset button or running bmode normal
|
|
will set it back to normal. This command currently

Vybrid (vf610) SoC provides some on-chip facility to tune the DDR3

memory parameters. Select this option if you want to calculate them
|
|
at boot time.
|
|
NOTE:
|
|
NXP does NOT recommend to perform this calibration at each boot. One
|
|
shall perform it on a new PCB and then use those values to program
|
|
the ddrmc_cr_setting on relevant board file.
