2019-06-28mach-stm32: Fix MPU region size dedicated to SDRAM for STM32F4Patrice Chotard1-1/+1
The MPU region dedicated for SDRAM for STM32F4 SoCs family was set to 16MB, but STM32F429 Evaluation board have 32MB of SDRAM. When kernel starts, only first 16MB of SDRAM are configured with XN (eXecute Never) bit disabled, whereas kernel is using 32MB. To avoid such situation in the future, extend this MPU region to 512MB as for STM32F7/H7. It fixes the following user land exception on STM32F429 Evaluation board : [ 1.713002] VFS: Mounted root (ext4 filesystem) readonly on device 179:2.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2-5/+2
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>
2018-03-14mach-stm32: Use default memory map as background regionPatrice Chotard1-25/+11
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.

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.
