> LPDDR3, DDR4 and LPDDR4.
> At the moment, the driver only supports DDR3 and LPDDR3 memory.
> Let's extend the driver to support the LPDDR4 memory. This type
> of memory widely used in device with T507(-H) SoC and new orangepi
> zero3 with H618.
> The compatibility with T507 is not yet complete, because there
> is difference in the phy_init array.
> The LPDDR4-2133 timings correspond to DRAM Rayson RS1G32LO4D2BDS-53BT
> found on the NOR SPI from the Orangepi Zero 3 4GB.
