Philipp Tomsich 297bb9e0fc sunxi: DRAM initialisation for sun9i 
This adds DRAM initialisation code for sun9i, which calculates the
appropriate timings based on timing information for the supplied
DDR3 bin and the clock speeds used.

With this DRAM setup, we have verified DDR3 clocks of up to 792MHz
(i.e. DDR3-1600) on the A80-Q7 using a dual-channel configuration.

[wens@csie.org: Moved dram_sun9i.c to arch/arm/mach-sunxi/; style cleanup]

default 0
---help---
Set the dram controller tpr3 parameter. This parameter configures
the delay on the command lane and also phase shifts, which are
applied for sampling incoming read data. The default value 0
means that no phase/delay adjustments are necessary. Properly
configuring this parameter increases reliability at high DRAM
clock speeds.
config DRAM_DQS_GATING_DELAY
hex "sunxi dram dqs_gating_delay value"
default 0
---help---
Set the dram controller dqs_gating_delay parmeter. Each byte
encodes the DQS gating delay for each byte lane. The delay
granularity is 1/4 cycle. For example, the value 0x05060606
means that the delay is 5 quarter-cycles for one lane (1.25
cycles) and 6 quarter-cycles (1.5 cycles) for 3 other lanes.
The default value 0 means autodetection. The results of hardware
autodetection are not very reliable and depend on the chip
temperature (sometimes producing different results on cold start
and warm reboot). But the accuracy of hardware autodetection
is usually good enough, unless running at really high DRAM
clocks speeds (up to 600MHz). If unsure, keep as 0.

used in Allwinner A10/A13/A20 devices. In the case of DDR3-1333
or DDR3-1600 chips, be sure to check the DRAM datasheet to confirm
that down binning to DDR3-1066F is supported (because DDR3-1066F
uses a bit faster timings than DDR3-1333H).
