Re: Re: [PATCH] [PATCH] ARM64: Setup DMA32 zone size by bootargs

Actually, In a embedded system with 3GB memory, the memory bus width is not the same among the 3GB. (The first 2GB is 48-bit wide, and the latter 1GB is 16-bit wide.) For memory throughput reason of hardware IPs, we need allocate memory from the first 2GB for the hardware IPs. And that is why we
