2018-07-12ddr: altera: Add ECC DRAM scrubbing support for Arria10Marek Vasut
The SDRAM must first be rewritten by zeroes if ECC is used to initialize the ECC metadata. Make the CPU overwrite the DRAM with zeroes in such a case. This scrubbing implementation turns the caches on temporarily, then overwrites the whole RAM with zeroes, flushes the caches and turns them off again. This provides satisfactory performance.

2018-07-12ddr: altera: Drop custom dram_bank_mmu_setup() on Arria10Marek Vasut
This function was never used in SPL and the default implementation of dram_bank_mmu_setup() does the same thing. The only difference is the part which configures OCRAM as cachable, which doesn't really work as it covers more than the OCRAM.
