We should use the algorithm in the Linux kernel so that the UART divisor
calculation is more accurate. It also fixes problems on some picky UARTs
that have sampling anomalies.

The rfcks should be shifted by 28 bits left. We didn't notice the bug
because we were using only 100MHz clocks (for which rfcks == 0).
Though, for SGMII we'll need 125MHz clocks.

Because some dimm parameters like n_ranks needs to be used with the board
frequency to choose the board parameters like clk_adjust etc. in the
board_specific_paramesters table of the board ddr file, we need to pass
the dimm parameters to the board file.
* move ddr dimm parameters header file from /cpu to /include directory.
* add ddr dimm parameters to populate board specific options.
* Fix fsl_ddr_board_options() for all the 8xxx boards which call this function.

At least some revisions of the 8313, and possibly other chips, do not
wait for all pages of the initial 4K NAND region to be loaded before
beginning execution; thus, we wait for it before branching out of the
first NAND page.
This fixes warm reset problems when booting from NAND on 8313erdb.

Set the MQ Read Passing & MCIF Cycle limits to the recommended by AMCC
values. This fixes the occasional 440SPe hard locking issues when the 440SPe's
dedicated DMA engines are used (e.g. by the h/w accelerated RAID driver).
Previously the appropriate initialization had been made in Linux, by the
ppc440spe ADMA driver, which is wrong because modifying the MQ configuration
registers after normal operation has begun is not supported and could
have unpredictable results.
Comment from Stefan: This patch doesn't change the resulting value of the
MQ registers. It explicitly sets/clears all bits to the desired state which
better documents the resulting register value instead of relying on pre-set
default values.

At a lot of places in the code the PIPE_INTERRUPT flags and friends
are used wrong. The wrong bits are compared to this flag resulting
in wrong conditions. Also there are macros that should be used for
PIPE_* flags.
This patch tries to fix them all, however, I was not able to test the
changes, because I do not have any of these boards.

is wrong by a factor of 1.5. Obviously, the interpretation of the
