The VX900 can be connected to either DDR2 or DDR3. On my board, it is
DDR3, hence why there is no and will be no DDR2 code from my side.
This is the raminit for DDR3 dimms for the VX900. I like the term
"raminit" better than "memory training". This is a device, not a dog.
What works and what doesn't is documented in the code. It does not

Take a Parmer board with 4G memory as an example.
Use 'cat /proc/meminfo' to check memory, it reads 'MemTotal 3327540kB'.
Parmer uses 512M as video memory when it has 4G.
3327540+512*1024 = 3851828(kB), so some memory is lost.
When Parmer has 4G memory, TOM2 low is 0x1F000000, TOM2 high is
0x00000001. But in e820 table or coreboot table, the last item is
6: 0000000100000000 - 0000000118000000 = 1 RAM
This is not correct, it should be

This patch changes the memory layout when TOM2 is set.

Split the Persimmon DSDT into common code areas.
For example, split the Southbridge specific code into
the Southbridge directory and CPU specific code into
the CPU directory. Also adding the superio.asl file
to the Persimmon DSDT tree. This file is empty for
the moment but will be necessary in the future. I have
also emptied the thermal.asl file in the mainboard
directory because it does not seem to perform as
intended (fan control does not change when it is
brought back into the code base) and it has been
inside a '#if 0' statement for a long time. Removing
it until it is decided that it is actually necessary.
This change was verified in three different ways:
1. Visual comparison of the compiled DSDT pulled from the
Persimmon after booting into Linux using the ACPI tools
acpidump, acpixtract, and iasl. The comparison was done
between the DSDT before and after doing the split work.
This test is somewhat difficult considering the expanse
of the changes. Blocks of code have been moved, and
others changed.
2. Linux logs were dumped before and after the DSDT split.
Logs dumped and compared include dmesg and lspci -tv.
Neither log changed significantly between the two compare
points.
3. The test suite FWTS was run on the Coreboot build both
before and after doing the DSDT split with the command
'sudo fwts -b -P -u'. The flag -b specifies all batch jobs,
-P specifies all power tests, and -u specifies utilities.
Interactive jobs were not run as most of them consist of
laptop checks. Again, there were no significant changes
between the two endpoints.
These tests lead me to believe that there was no change in
the functionality of the ACPI tables apart from what is
known and expected.
This patch is the first of a series of patches to split the DSDT.
The ASRock patch was merged before this one and breaks the ASROCK
E350M1 build (patch 8d80a3fb: http://review.coreboot.org/#/c/3050/).

ACPI reported the entire space between top-of-memory and some
(relatively) arbitrary limit as useful for MMIO. Unfortunately
the HyperTransport configuration disagreed. Make them match up.
Other boards are not affected since they don't report any region
for that purpose at all (it seems).

The old MTRR code had issues using too many variable
MTRRs depending on the physical address space layout dictated
by the device resources. This new implementation calculates
the default MTRR type by comparing the number of variable MTRRs
used for each type. This avoids the need for IORESOURE_UMA_FB
because in many of those situations setting the default type to WB
frees up the variable MTTRs to set that space to UC.
Additionally, it removes the need for IORESOURCE_IGNORE_MTRR
becuase the new mtrr uses the memrange library which does merging
of resources.
Lastly, the sandybridge gma has its speedup optimization removed
for the graphics memory by writing a pre-determined MTRR index.
That will be fixed in an upcoming patch once write-combining support
is added to the resources.
Slight differences from previous MTRR code:
- The number of reserved OS MTRRs is not a hard limit. It's now advisory
as PAT can be used by the OS to setup the regions to the caching
policy desired.
- The memory types are calculated once by the first CPU to run the code.
After that all other CPUs use that value.
- CONFIG_CACHE_ROM support was dropped. It will be added back in its own
change.
A pathological case that was previously fixed by changing vendor code
to adjust the IO hole location looked like the following:
MTRR: Physical address space:
0x0000000000000000 - 0x00000000000a0000 size 0x000a0000 type 6
0x00000000000a0000 - 0x00000000000c0000 size 0x00020000 type 0
0x00000000000c0000 - 0x00000000ad800000 size 0xad740000 type 6
0x00000000ad800000 - 0x00000000d0000000 size 0x22800000 type 0
0x00000000d0000000 - 0x00000000e0000000 size 0x10000000 type 1
0x00000000e0000000 - 0x0000000100000000 size 0x20000000 type 0
0x0000000100000000 - 0x000000014f600000 size 0x4f600000 type 6
As noted by the output below it's impossible to accomodate those
ranges even with 10 variable MTRRS. However, because the code
can select WB as the default MTRR type it can be done in 6 MTRRs:
MTRR: default type WB/UC MTRR counts: 6/14.
MTRR: WB selected as default type.
MTRR: 0 base 0x00000000ad800000 mask 0x0000007fff800000 type 0
MTRR: 1 base 0x00000000ae000000 mask 0x0000007ffe000000 type 0
MTRR: 2 base 0x00000000b0000000 mask 0x0000007ff0000000 type 0
MTRR: 3 base 0x00000000c0000000 mask 0x0000007ff0000000 type 0
MTRR: 4 base 0x00000000d0000000 mask 0x0000007ff0000000 type 1
MTRR: 5 base 0x00000000e0000000 mask 0x0000007fe0000000 type 0
