| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When attempting to use the existing configuration file to bootstrap an RMU2 board, openocd would consistently fail in the 'safe_reset' function with a number of errors. Disabling the internal reset handling (similar to what's done on the i.MX7 Sabre boards) allowed barebox to download and run successfully. Tested with openocd-0.10.0+dev-00924-g16496488 on a Zodiac RMU2.

|/ | | | | | | | | | | | | | | When attempting to use the existing configuration file to bootstrap an SCU4 AIB board, openocd would consistently fail on the 'halt' command with a "Target not examined yet" error. Dumping target information showed that vf610.cpu1 was the active target, rather that vf610.cpu0. Adding a command prior to the halt to explicitly set the target core resulted in proper operation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As observed on CFU1 board, without this delay we interrupt mask ROM code execution even before it sets up any PLLs correctly preventing Barebox from correctly starting up. Fixing this by adding PLL setup code to OpenOCD script helps somewhat and Barebox starts, howerver CPU started this way ends up being unstable crashing randomly during further Barebox use. Adding a simple 100 ms post reset delay resolves all of the described issues. This is also consistent with how other ZII boards are set up.

|/ | | | | | | | | | | | | | | 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.

| * ARM: rpi: save bootargs from VC FDT to vc.bootargsTomaz Solc2019-03-041-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
