V3s devices won't have enough memory to load U-Boot binary at 0x4a000000, and they do not have enough memory to reserve 64MiB for malloc() (it has only 64MiB at all!) Change the text base to 0x41000000, and cut down malloc() reserved area to 4MB, in order to fit into the small DRAM of V3s.

Can't this be used for all the SoCs? Allocating 64MB seems way to much already :)

This patch is obsolute now.

A newer version which enables booting a kernel is ready now, on my github.

And according to someone in linux-sunxi, some works, for example enable a UBIFS, eats a lot of heap.
