3326 is more like a PX30
derivative chip. This is not the same as the previous chips.
So we use PX30 instead of RK3326 for name, and the opening document is only for
PX30, we think this is more convenient for developers.

In order to be able to use more than 4GB of RAM when the LPAE is
activated, the dts must be converted in 64 bits.

Another way to support 64-bit memory is create a soc subnode, and move all
peripherals to this subnode. But it will break userspace compatibility.
For
Rockchip RK3288 has some 64-bit capable DMA and therefore needs
dma_addr_t to be a 64-bit size. One user is the Mali GPU.

Most IP cores on ARM Rockchip platforms can only address 32 bits of
physical memory for DMA. Thus ZONE_DMA should be enabled when LPAE
is activated.
