Series [U-Boot,1/2] bouncebuf: Add static buffer allocation method for SPL. | expand

Since the DMA-engine of the RK3399 cannot directly copy the
ATF SRAM/PMUSRAM memory sections to their destination, we need
to use bounce-buffers. This results in allocation of a huge amount
of heap memory, which can't be reused (because of simple-malloc).

Therefore we enable the static bounce buffer method.
