[PATCH 5/7] MIPS: ingenic: Add support for the JZ4725B SoC

[Paul Cercueil]

Add preliminary support for boards based on the JZ4725B SoC from
Ingenic.

The JZ4725B SoC is supposed to be older than the JZ4740 SoC, but its
internals are much closer to what can be found on the JZ4750 and newer
SoCs.

It is low-power SoC with a MIPS32r1 SoC running at ~360 MHz, and no FPU.

[PATCH 6/7] MIPS: ingenic: Add support for the RS90 board

[Paul Cercueil]

The RS-90, better known as RetroMini, is a small and pocketable handheld
gaming console from YLMChina. It has little more than a JZ4725B SoC, a
NAND, a screen, some buttons and a speaker.
