The DDR validation tool (which is part of Processor Expert) allows
to evaluate leveling parameters for CR105/CR106/CR110. Several
runs have been made with Colibri VF50 and VF61 and it seems to
evaluate very similar values. Use this values by default.
Note: The newly evaluated parameters seem to require CTLUPD_AREF
to be enabled!
Note 2: The tool also evaluated 6 as a new value for PHY02/18
GATE_CFG (Coarse adjust of gate open time). However, this seems
not to work in practise.

We have two commands to change the bootmode fuses:
mfgr_fuse which set fuse 0/5 and 0/6
and
updt_fuse which burns bit 4 of 0/5.
Before Image 2.6 we fused in mfgr_fuse 0x5062, which boots
from the user partition of the eMMC.
To workaround certain hangs we moved to fastboot mode and
using the first bootpartition of the eMMC requiring a fuse
value of 0x5072 which could be achived by the then added
updt_fuse command. At the same time the mfgr_fuse command
was changed to also fuse 0x5072, revert that second change
so that one can fuse both values, one with just mfgr_fuse
and the later with mfgr_fuse;updt_fuse.
Note that the mfgr_fuse command is only needed at module
production time, a customer might need to use updt_fuse
when upgrading an older module to be compatible with a
newer image. The command is integrated into the image
update scripts.

Rather than passing a hardcoded maxsize to the generic get_ram_size()
function use the i.MX 7 specific imx_ddr_size() function, which extracts
the memory size at runtime by reading the DDR controller registers.
This is a purely cosmetic change as the generic get_ram_size() function
already took care of properly automatically detecting 256MB, 512MB or 1GB
modules.

This makes sure that all Colibri iMX7 modules work with the
same timing. The changes are:
- Disable ODT on read (JEDEC standard JESD79-3F says in chapter
5.2.3 ODT during Reads: "As the DDR3 SDRAM can not terminate
and drive at the same time, RTT must be disabled at least half
a clock cycle..." and also MX7D SABRESD is disabling it)
This alone fixed memory issues for two Colibri iMX7 1GB modules
which showed issues before
- Make sure tRFC(min) is at least 260ns
- Make sure tRC is >50.625ns
- tRP needs to be >13.125ns, we can lower from 18.75ns to 15ns
- tFAW is not relevant, leave at reset
