0bd20207ab ARM: uniphier: disable cache in SPL of PH1-LD20 
The Boot ROM has enabled D-cache and MMU setting DDR memory area

5eb4150e84 ARM: uniphier: allow to use System Bus for ROM boot mode of PH1-LD20 
The System Bus is not available by default on the ROM boot mode of
PH1-LD20.  To use devices connected to the System Bus, such as the
Micro Support Card, it is necessary to set up pin-muxing and some
System Bus Controller register.
