Description

Native raminit failed with: "edge write discovery failed".
It's failing on channel 1 with two DIMMs installed, while it has no problems booting with a single DIMM.
The test fails on lane 1.
These are the Cvals of channel 1:
Cval: 1, 1, 0, 26
Cval: 1, 1, 1, 21
Cval: 1, 1, 2, 41
Cval: 1, 1, 3, 4d
Cval: 1, 1, 4, 4e
Cval: 1, 1, 5, 52
Cval: 1, 1, 6, 2c
Cval: 1, 1, 7, 5e

Cval: 1, 0, 0, 22
Cval: 1, 0, 1, 5e
Cval: 1, 0, 2, 3b
Cval: 1, 0, 3, 4a
Cval: 1, 0, 4, 4a
Cval: 1, 0, 5, 4c
Cval: 1, 0, 6, 29
Cval: 1, 0, 7, 5b

Values for the same lane are about the same (+- 6units), but only lane 1
shows a huge offset of 61.

By adding a simple check to timB discovery:

 FOR_ALL_LANES {
               if (((ctrl->timings[channel][slotrank].lanes[lane].timB & 0x3f) == 0x3e) ||
                       ((ctrl->timings[channel][slotrank].lanes[lane].timB & 0x3f) == 0x3f))
               ctrl->timings[channel][slotrank].lanes[lane].timB += 2;
 }

The issue is fixed for me.
This patch just covers the problem instead of fixing it.

Should be fixed in latest git.
Needs tests on x230.

Native ram init should really work, as I'm using 2 DIMMs and at least with ram init I don't have a problem.
I append a cdbmem log, with ram debug enabled, in case that helps.
