According to MX6 TRM, both MMDC and DRAM should be configured to
the same powerdown precharge. Currently, mx6_dram_cfg()
configures MMDC for fast pd (MDPDC[7] = 0), and the DRAM for
'slow exit (DLL off)' (MR0[12] = 0).

Configure MMDC for slow pd.

The IMX6 MMDC calibration registers depend on propagation delay and capacitive
loading between the SoC's MMDC and the DDR3 chips. On the Ventana boards the
board layout varies little in trace-lengths such that propagation delays are
irrelevant thus we can simply things by using calibration values obtained
from various board layouts based on a common SoC and DDR chip configuration.

This eliminates board-model from being needed allowing more flexibility. These
values were tested on a large sample size of Gateworks Ventana boards ranging
in layout, and memory configuration over the entire temperature range supported.

When testing the FEC driver on a mx6solox we noticed that the TDAR bit gets
always cleared prior then the READY bit is cleared in the last BD, which causes
FEC packets reception to always fail.

As explained by Ye Li:

"The TDAR bit is cleared when the descriptors are all out from TX ring, but on
mx6solox we noticed that the READY bit is still not cleared right after TDAR.
These are two distinct signals, and in IC simulation, we found that TDAR always
gets cleared prior than the READY bit of last BD becomes cleared.
In mx6solox, we use a later version of FEC IP. It looks like that this
intrinsic behaviour of TDAR bit has changed in this newer FEC version."

Fix this by polling the READY bit of BD after the TDAR polling, which covers the
mx6solox case and does not harm the other SoCs.

No performance drop has been noticed with this patch applied when testing TFTP
transfers on several boards of different i.mx SoCs.

mx6solox has a requirement for 64 bytes alignment for RX DMA transfer.
Other SoCs work with the standard 32 bytes alignment.

Adjust it accordingly by using 64 bytes aligment in the FEC RX DMA buffers,
which addresses the needs from mx6solox and also works for the other SoCs.

in the DWMMC mode by the cpu software reset. Manual reset of the card
by switching proper gpio pin - fixes this issue.
