Rockchip SoCs bootrom design is like this:
- First 2KB or 4KB internal memory is for bootrom stack and heap;
- Then the first 4-byte suppose to be a TAG like 'RK33';
- The the following memory address end with '0004' is the first
instruction load and running by bootrom;
Let's use the boot0 hook to reserve the first 4-byte tag for all
the Rockchip SoCs.
