	b4db05f Browse files » ARM: rpi: move debug UART Kconfig settings ... In contrast to other architectures, R.Pi debug UART config was placed under the "System Type" menu, not under the "Debugging -> low-level debugging port". This made this setting easy to miss when enabling low level debug mesages. While at it use the existing base address defines rather than defining them again in Kconfig.

2019-03-04	67e38cd Browse files » ARM: rpi: save bootargs from VC FDT to vc.bootargs ... When booting a Raspberry Pi, it is useful to extract bootargs from the device tree that was created by the VideoCore firmware. These bootargs contain for example settings for the framebuffer that the kernel needs to properly set the video output. This commit extracts the bootargs in the board initialization code and saves them to the vc.bootargs global variable. For example, a bootloader environment can then add the contents of this variable to linux.bootargs.vc, which then gets included into the final bootargs for the kernel using CONFIG_FLEXIBLE_BOOTARGS.

	e390c87 Browse files » ARM: rpi: save fdt that was passed from VideoCore ... On Raspberry Pi, VideoCore firmware creates a device tree that contains information about peripherals that were initialized by VideoCore based on settings in config.txt. Normally this device tree is passed to the Linux kernel via a pointer in the r2 register. A bootloader needs to pass this device tree to the kernel, or some peripherals will not work correctly. Since the VideoCore device tree is not compatible with barebox, we can't just pass it to barebox_arm_entry() as the internal barebox device tree. This commit makes the prebootloader code copy the device tree from VideoCore into a scrap RAM area just above the area reserved for the bootloader. Board initialization code in the bootloader proper then copies it into a file /vc.dtb. The bootloader environment is then free to pass this file to the kernel at boot (e.g. via bootm -o).

Knowing the address of the end of the memory area used by Barebox is useful if PBL stores some extra data after it, so that board init code can later retrieve it from there.

Otherwise the pinctrl device tree properties in the mci node are ignored. pinctrl is initialized by coredevice_initcall(), so moving mci-bcm2835 to device_initcall() ensures that it is initialized later. There is no reason for mci-bcm2835 to use coredevice_initcall(). Other mci drivers already use device_initcall().

On Raspberry Pi 3, sdhost is normally used for SD card/MMC flash and sdhci for the wireless interface. Barebox currently only has a driver for sdhci, so we disable the sdhost interface and remap the pins so that the sdhci has access to the SD card/MMC flash.
