Drop static tables which map the bits in F2x80 to a chip select size in
favor of functions doing the mapping with some bit fiddling. Also, add
F15 support.

This function is relevant for F10h and higher, and it has only one

F15h sys_addr to chip select mapping is almost identical to F10h's so
reuse that. Rename functions on that path accordingly.

When node interleaving is enabled, a subset of the addr[14:12] bits has
to be removed in order to get the normalized DCT address of the DRAM
channel. The actual number of bits to remove is determined by F1x[1,
0][7C:40][IntlvEn]. Do this correctly.

On revC3 and revE Fam10h machines and later, non-interleaved graphics
framebuffer memory under the 16G mark can be swapped with a region
located at the bottom of memory so that the GPU can use the interleaved
region and thus two channels. Add support for that.

The only difference is that F10h used to sport ganged DCTs and F15h
doesn't so adjust the F10h routine and reuse it.

Remove reporting of errors with UC bit set - this is done by the MCE
decoding code anyway and this driver deals with DRAM ECC errors only. UC
(NB uncorrectable error) doesn't necessarily mean it is a DRAM error.
Remove unused macros while at it.

The fact whether we are chipkill capable or not does not have any
bearing when computing the channel index on a ganged DCT configuration
so remove that. Also, simplify debug statements. Finally, remove old
error injection leftovers, while at it.

* Restrict DCT ganged mode check since only Fam10h supports it
* Adjust DRAM type detection for BD since it only supports DDR3
* Remove second and thus unneeded DCLR read in k8_early_channel_count() - we do
that in read_mc_regs()
* Cleanup comments and remove family names from register macros
* Remove unused defines

This function maps the system address to the normalized DCT address.
Document what the code does for more clarity and wrap insane bitmasks in
a more understandable macro which generates them. Also, reduce number of
arguments passed to the function. Finally, rename this function to what
it actually does.

Cleanup and simplify f10_determine_channel(); make it more readable.
Also drop f10_map_intlv_en_to_shift() in favor of simply counting the

Add a struct representing the DRAM chip select base/limit register
pairs. Concentrate all CS handling in a single function. Also, add CS
looping macros for cleaner, more readable code. While at it, adjust code
to F15h. Finally, do smaller macro names cleanups (remove family names
from register macros) and debug messages clarification.

Add a struct representing the DRAM base/limit range pairs and remove all
cached subfields. Replace them with accessor functions, which actually
saves us some space:
text data bss dec hex filename
14712 1577 336 16625 40f1 drivers/edac/amd64_edac_mod.o.after
14831 1609 336 16776 4188 drivers/edac/amd64_edac_mod.o.before
Also, it simplifies the code a lot allowing to merge the K8 and F10h
routines.

F15h "multiplexes" between the configuration space of the two DRAM
controllers by toggling D18F1x10C[DctCfgSel] while F10h has a different
set of registers for DCT0, and DCT1 in extended PCI config space.
Add DCT configuration space accessors per family thus wrapping all the
different access prerequisites. Clean up code while at it, shorten
names.
