Subject: [PATCH v11 0/9] Add Sunplus SP7021 SoC Support
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.
