board: arm: Add support for Broadcom BCM7445

2018-07-10T20:55:57Z

Add support for loading U-Boot on the Broadcom 7445 SoC. This port assumes Broadcom's BOLT bootloader is acting as the second stage bootloader, and U-Boot is acting as the third stage bootloader, loaded as an ELF program by BOLT.

arm: armv7m: Clean up some thumb / compiler flag options

2018-05-23T17:03:42Z

- The correct way to build with thumb mode is to select SYS_THUMB_BUILD - We should be setting -march=armv7-m in arch/arm/Makefile not the sub-config.mk file. Signed-off-by: Tom Rini

arm: zynqmp: Add ZynqMP minimal R5 support

2018-05-11T07:38:23Z

Xilinx ZynqMP also contains dual Cortex R5 which can run U-Boot. This patch is adding minimal support to get U-Boot boot. U-Boot on R5 runs out of DDR with default configuration that's why DDR needs to be partitioned if there is something else running on arm64. Console is done via Cadence uart driver and the first Cadence Triple Timer Counter is used for time. This configuration with uart1 was tested on zcu100-revC.

arm: v7R: Add initial support

2018-05-07T19:53:28Z

The Cortex-R* processors are a mid-range CPUs for use in deeply-embedded, real-time systems. It implements the ARMv7-R architecture, and includes Thumb-2 technology for optimum code density and processing throughput. Except for MPU(Memory Protection Unit) and few CP15 registers, most of the features are compatible with v7 architecture. So,reuse the same armv7 folder and introduce a new config CPU_V7R in order to differentiate from v7 based platforms.

arm: v7: Kconfig: Rename CPU_V7 as CPU_V7A

2018-05-07T19:53:24Z

Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under armv7 folder. This led to a misconception of creating separate folders for armv7m and armv7r. There is no reason to create separate folder for other armv7 based architectures when it can co-exist with few Kconfig symbols. As a first step towards a common folder, rename CPU_V7 as CPUV7A. Later separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and can co exist in the same folder.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

arm: stm32: add new architecture for STM32MP family

2018-03-19T20:14:21Z

- add new arch stm32mp for STM32 MPU/Soc based on Cortex A - support for stm32mp157 SOC - SPL is used as first boot stage loader - using driver model for all the drivers, even in SPL - all security feature are deactivated (ETZC and TZC) - reused STM32 MCU drivers when it is possible Signed-off-by: Patrick Delaunay

imx: reorganize IMX code as other SOCs

2017-07-12T08:17:44Z

Change is consistent with other SOCs and it is in preparation for adding SOMs. SOC's related files are moved from cpu/ to mach-imx/. This change is also coherent with the structure in kernel.
