Patrick Rudolph 6f7ce9b217 intel raminit: fix timB high adjust calculation
Issue observed:
Any memory DIMM placed in channel0 slots stops at "c320c discovery failed".
The same memory DIMM works when placed in channel1 slots.

Test system:
 * Intel Pentium CPU G2130
 * Gigabyte GA-B75M-D3H
 * DIMMs:
  * elixir 1GB 1Rx8 PC3-10600U M2Y1G64CB88A5N
  * crucial 2GB 256Mx64 CT2566aBA160BJ
  * corsair 8GB CMZ16GX3M2A1866C9

Problem description:
In case of good timmings (all bits are set) an offset of 3*64 was applied.
The following test (c320c discovery) failed only on those byte-lanes.

Problem solution:
Don't modify timB in case of good timings measured.

Final testing result:
The system boots with every DIMM placed in channel 0 slots.

coreboot README
-------------------------------------------------------------------------------

coreboot is a Free Software project aimed at replacing the proprietary BIOS
(firmware) found in most computers.  coreboot performs a little bit of
hardware initialization and then executes additional boot logic, called a
payload.

With the separation of hardware initialization and later boot logic,
coreboot can scale from specialized applications that run directly
firmware, run operating systems in flash, load custom
bootloaders, or implement firmware standards, like PC BIOS services or
UEFI. This allows for systems to only include the features necessary
in the target application, reducing the amount of code and flash space
required.

coreboot was formerly known as LinuxBIOS.


Payloads
--------

After the basic initialization of the hardware has been performed, any
desired "payload" can be started by coreboot.

See http://www.coreboot.org/Payloads for a list of supported payloads.


Supported Hardware
------------------

coreboot supports a wide range of chipsets, devices, and mainboards.

For details please consult:

 * http://www.coreboot.org/Supported_Motherboards
 * http://www.coreboot.org/Supported_Chipsets_and_Devices


Build Requirements
------------------

 * gcc / g++
 * make

Optional:

 * doxygen (for generating/viewing documentation)
 * iasl (for targets with ACPI support)
 * gdb (for better debugging facilities on some targets)
 * ncurses (for 'make menuconfig')
 * flex and bison (for regenerating parsers)


Building coreboot
-----------------

Please consult http://www.coreboot.org/Build_HOWTO for details.


Testing coreboot Without Modifying Your Hardware
------------------------------------------------

If you want to test coreboot without any risks before you really decide
to use it on your hardware, you can use the QEMU system emulator to run
coreboot virtually in QEMU.

Please see http://www.coreboot.org/QEMU for details.


Website and Mailing List
------------------------

Further details on the project, a FAQ, many HOWTOs, news, development
guidelines and more can be found on the coreboot website:

You can contact us directly on the coreboot mailing list:
