This patch series add Sunplus SP7021 SoC support. Sunplus SP7021 is an ARM Cortex A7 (4 cores) based SoC. It integrates many peripherals (ex: UART, I2C, SPI, SDIO, eMMC, USB, SD card and etc.) into a single chip. It is designed for industrial control. SP7021 consists of two chips (dies) in a package. One is called C-chip (computing chip). It is a 4-core ARM Cortex A7 CPU. It adopts high-level process (22 nm) for high performance computing. The other is called P- chip (peripheral chip). It has many peripherals and an ARM A926 added especially for real-time control. P-chip is made for customers. It adopts low-level process (ex: 0.11 um) to reduce cost.
