2018-06-05mach-stm32: Enable SPL_RESET_SUPPORT flagPatrice Chotard
Since commit 0e373c0ade8c ("spl: add SPL_RESET_SUPPORT"), reset is supported in SPL, enable this flag for STM32F SoCs family. This allows to remove a specific case in RCC mfd driver. Signed-off-by: Patrice Chotard <patrice.chotard@st.com>
2018-05-07arm: v7R: Add support for MPULokesh Vutla
The Memory Protection Unit(MPU) allows to partition memory into regions and set individual protection attributes for each region. In absence of MPU a default map[1] will take effect. Add support for configuring MPU on Cortex-R, by reusing the existing support for Cortex-M processor.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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 <trini@konsulko.com>
2018-03-13mach-stm32: Use default memory map as background regionPatrice Chotard
On linux kernel side, on STM32F7 and STM32H7 SoCs, DMA requires uncachable regions. These regions are defined in DT. Since kernel linux v4.15, on ARMv7-M Cortex, kernel is able to configure MPU regions depending on DT settings. As kernel is able to configure MPU, this allows to remove MPU region settings in bootloader. On Cortex M processors, MPU allows to use a default memory map. (see B3.5.4 MPU Control Register, MPU_CTRL in https://developer.arm.com/products/architecture/m-profile/docs/ddi0403/latest/armv7-m-architecture-reference-manual) Use the default memory map as background region for all STM32 SoCs family with an additional MPU region corresponding to the SDRAM area.

With xip booting configuration, we don't need to copy the next image (U-Boot or linux xipimage) from flash to sdram area. Flash memory organization is like this: spl-U-Boot: u-boot-spl.bin : 0x0800_0000 U-Boot : u-boot-dtb.bin : 0x0800_8000 linux : xipImage : 0x0800_8000 It is also possible to have U-Boot binary & linux binaries configured at different addresses of flash memory like U-Boot at 0x0800_8000 & linux xipImage at 0x0800_4000. But in any case, spl-U-Boot needs to be compiled for U-Boot as next binary with SPL_OS_BOOT option disabled. By default, spl is configured to boot linux xipImage.

2016-07-14stm32: Change USART port to USART6 for stm32f746 discovery boardToshifumi NISHINAGA
This change is to remove a halt at about 200KiB while sending a large(1MiB) binary to a micro controller using USART1. USART1 is connected to a PC via an on-board ST-Link debugger that also functions as a USB-Serial converter. However, it seems to loss some data occasionally. So I changed the serial port to USART6 and connected it to the PC using an FTDI USB-Serial cable, therefore the transmission was successfully completed.
