This patchset update Stratix 10 SDRAM driver to support: - Multi-banks memory - Stratix 10 support up to 2 memory banks: Bank 0: Address 0, size 2GB Bank 1: Address 0x100000000, size 124GB - Add warm reset boot checking function (Patch[5]) - Add ECC memory scrubbing support (Patch [6]) - Use cache enabled + "DC ZVA" instruction to clear memory to zeros
v1 -> v2: --------- - Decode memory bank configuration from device tree - Use asm volatile() and "memory" clobber
History: -------- v1: https://patchwork.ozlabs.org/cover/1055134/
