[PATCH v2 0/6] Enhance DDR support for Arria10 SoCFPGA

[Naresh Kumar Ravulapalli]

DDR driver of Arria10 SoCFPGA is enhanced in below ways:
a) Check DRAM size from device tree and actual hardware,
   mismatch is notified to the user
b) In case DRAM size from device tree is greater than actual
   hardware, DRAM size is initialized to the hardware value
c) Fix a bug during computation of mpu1 address
d) Move common code specifically, initializing SDRAM ECC bits to a
   common sdram_soc32 file. This allows using the same code for
   future devices.
e) DRAM initialization is sped up by enabling Dcache

Changes in v2:
- Avoid hang if DRAM size from device tree is greater than
  actual hardware
- Correct ECC Scrubbing commit message to appropriate one
- Address minor comments in v1
