From: TracyMg_Li TracyMg_Li@outlook.com

Add pe2201 platform code and the device tree of pe2201 platform board. The initial support comprises the UART and PCIe.

Signed-off-by: TracyMg_Li TracyMg_Li@outlook.com Changes since v1: fix space corrupt. Changes since v2: switch to bootstd and text environment. Changes since v3: add environment variables. --- arch/arm/Kconfig | 7 ++ arch/arm/dts/Makefile | 1 + arch/arm/dts/phytium-pe2201.dts | 43 +++++++ board/phytium/pe2201/Kconfig | 12 ++ board/phytium/pe2201/MAINTAINERS | 8 ++ board/phytium/pe2201/Makefile | 12 ++ board/phytium/pe2201/cpu.h | 64 +++++++++++ board/phytium/pe2201/ddr.c | 190 +++++++++++++++++++++++++++++++ board/phytium/pe2201/pcie.c | 60 ++++++++++ board/phytium/pe2201/pe2201.c | 92 +++++++++++++++ board/phytium/pe2201/pe2201.env | 25 ++++ board/phytium/pe2201/pll.c | 75 ++++++++++++ board/phytium/pe2201/sec.c | 37 ++++++ configs/pe2201_defconfig | 42 +++++++ include/configs/pe2201.h | 16 +++ 15 files changed, 684 insertions(+) create mode 100644 arch/arm/dts/phytium-pe2201.dts create mode 100644 board/phytium/pe2201/Kconfig create mode 100644 board/phytium/pe2201/MAINTAINERS create mode 100644 board/phytium/pe2201/Makefile create mode 100644 board/phytium/pe2201/cpu.h create mode 100644 board/phytium/pe2201/ddr.c create mode 100644 board/phytium/pe2201/pcie.c create mode 100644 board/phytium/pe2201/pe2201.c create mode 100644 board/phytium/pe2201/pe2201.env create mode 100644 board/phytium/pe2201/pll.c create mode 100644 board/phytium/pe2201/sec.c create mode 100644 configs/pe2201_defconfig create mode 100644 include/configs/pe2201.h
