Andre Przywara 78aa00c38e sunxi: H616: dram: split struct dram_para ... Currently there is one DRAM parameter struct for the Allwinner H616 DRAM "driver". It contains many fields that are compile time constants (set by Kconfig variables), though there are also some fields that are probed and changed over the runtime of the DRAM initialisation. Because of this mixture, the compiler cannot properly optimise the code for size, as it does not consider constant propagation in its full potential. Help the compiler out by splitting that structure into two: one that only contains values known at compile time, and another one where the values will actually change. The former can then be declared "const", which will let the compiler fold its values directly into the code using it. We also add "const" tags for some new "struct dram_config" pointers, to further increase code optimisation. To help the compiler optimise the code further, the definition of the now "const struct dram_para" has to happen at a file-global level, so move that part out of sunxi_dram_init(). That results in quite some code savings (almost 2KB), and helps to keep the code small with the LPDDR3 support added later.
