Instead of hardcode the base address, we can get them from the build output, eg. get the SYS_TEXT_BASE from .config and get optee base from DRAM_BASE. We can use this script for SoCs with DRAM base not from 0x60000000(rk3229 and many other 32bit Rockchip SoCs), eg. rk3288 DRAM base is 0. Signed-off-by: Kever Yang <kever.yang@rock-chips.com>
