* ARM64: qemu-virt64: migrate to generic DT imageAhmad Fatoum2021-03-171-1/+2
| | | | | | | | | | | | | | | | | | | | | | Current qemu-virt64 barebox support doesn't look much like what's offered on physical boards. It's not relocatable, lacks PBL and doesn't use device tree. As qemu-system-aarch64 -M virt -kernel already supplies an external device tree, we could just replace all existing support with BOARD_ARM_GENERIC_DT, which builds a barebox image that reuses an externally passed device tree. The 32-bit ARM VIRT support has some board code for host name setting and overlay applying to handle environment and state on flash. We could do without that, given the new virtio-blk support, but the code is already there, so reuse it and drop all current virt64-specific board code. As the barebox ELF image resulting from the build can no longer be directly booted as before and only with -kernel, not -bios, rename the Kconfig symbol, so existing users can notice this during build.

* doc: bcm283x: document use of mini-uart on Raspberry Pi Zero W / CM3Ahmad Fatoum2020-12-101-0/+7
| | | | | | | | | | | | | | | | | | As described in the UART configuration[1] article in the Raspberry Pi Foundation documentation, Raspberry Pi 3 & 4 as well as Zero W use the mini-uart as primary (easily user-accessible) UART. At least on the Raspberry Zero W and CM3, we need to pass uart_2ndstage=1, so the BootROM leaves the 8250 IP in a suitable state for use by barebox. Document this.
