90f740a06a rockchip: sdram: fix dram_init_banksize
Currently 2.5 GB is calculated as DRAM size for a 1 GB RK322x board
if CONFIG_SPL_OPTEE is set. This is troublesome when booting a
linux kernel since this size will be injected in FDT of the kernel.

gd->bd->bi_dram[0].start (which is basically CONFIG_SYS_SDRAM_BASE)
must not be taken into consideration for calculation of second bank
size, since this offset is already included in calculation of "top".

After applying this patch 992 MB (1024 MB - 32 MB reserved for
optee-os) is correctly calculated and has also been verified on
2 GB boards.

67c4e9f815 common: Move board_get_usable_ram_top() out of common.h
Move this function into init.h which seems to be designed for this sort
of thing. Also update the header to declare struct global_data so that it
can be included without global_data.h being needed.

c7becc3a2b rockchip: sdram: update the sys_reg to sys_reg2
We are using sys_reg2 and sys_reg3 as ddr cap info, sync the variable
name to what we real use to avoid confuse people.

9a46f2a4cb rockchip: sdram: extend to use sys_reg3 for capacity info
Since we have new DRAM type and to support different DRAM size in different
CS, we need more bits, so introduce sys_reg3 to record the info.
Note that the info in sys_reg3 is extension to sys_reg2 and the info in
sys_reg2 is the same as before. We define the DRAM_INFO with sys_reg3 as
VERSION2.
All the ENC macro are moved to sdram_common.h since the sdram.c only
need to do the info decode.

5d19ddf0db ram: rockchip: rename sdram_common.c/h to sdram.c
rename sdram_common.c in arch/arm/mach-rockchip to sdram.c;
so that we can use the file name sdram_common.c in dram driver for
better understand the code;
clean the related file who has use the header file at the same time.
