sunxi: change maximum DRAM size to 3G #6

Closed Icenowy closed 6 years ago

Icenowy commented 6 years ago

The DRAM space allocated in A64/H5 memory map is 3G, and it's possible to use all of it by using a memory chip bigger than 3G (so 4G chip is used; it's wasteful, but it do enables the CPU to access more memory).

Change the maximum DRAM size to 3G, then the last 1G will be also mapped to the virt address space.

DRAM mapping is not needed at all, also this repo is obsolete. Closing.
