2020-05-12arm: dts: bcm283x: Allow UARTs to work before relocationSimon Glass
At present the pinctrl nodes are not enabled in pre-relocation U-Boot so the UARTs do not correctly select the pinconfig to enable the UART pins. Fix this so that the U-Boot banner is printed. This fixes serial output on rpi_3b_32b with the following config.txt options: enable_uart=1 gpu_freq=250 Signed-off-by: Simon Glass <sjg@chromium.org> Fixes: 9821636b64 (bcm2835_pinctrl: Probe pre-reloc) Signed-off-by: Matthias Brugger <mbrugger@suse.com>
2019-11-24arm: dts: bcm283x: Rename U-Boot fileMatthias Brugger
Rename the file bcm283x-uboot.dtsi so that it get automatically include through the scripts/Makefile.lib using $(CONFIG_SYS_SOC))-u-boot.dtsi Without this uarts and pincontroller miss the property dm-pre-reloc and the first call to bcm283x_mu_serial_ofdata_to_platdata() fails as the pins are not set correctly. As a result the U-Boot banner isn't shown on boot. Before commmit 143256b353 ("fdt: update bcm283x device tree sources to Linux 5.1-rc6 state") we included bcm283x-uboot.dtsi directly in the device-tree file. Which got deleted by the metioned commit. This is a much robuster solution.
