2019-06-18	3a14fb7 Browse files » Documentation: user: suggest U-Boot's bootm, not go ... Unlike barebox, U-Boot's go command doesn't have any provisions for cache handling and as such, bootstrapping barebox via go can cause stale data to be erroneously executed as instructions. The official documentation[1] suggests use of bootm instead, which does the necessary flushing and invalidation. Update our documentation accordingly.

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.

2019-03-04	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).
