From 6cbb41432d3af94861568c3cfb057c3d9cbd994b Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 22 Mar 2020 21:15:52 -0600 Subject: arm: dts: bcm283x: Allow UARTs to work before relocation 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 Fixes: 9821636b64 (bcm2835_pinctrl: Probe pre-reloc) Signed-off-by: Matthias Brugger --- arch/arm/dts/bcm283x-u-boot.dtsi | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'arch') diff --git a/arch/arm/dts/bcm283x-u-boot.dtsi b/arch/arm/dts/bcm283x-u-boot.dtsi index 36548dad62..68d03627f4 100644 --- a/arch/arm/dts/bcm283x-u-boot.dtsi +++ b/arch/arm/dts/bcm283x-u-boot.dtsi @@ -19,3 +19,11 @@ &gpio { u-boot,dm-pre-reloc; }; + +&uart0_gpio14 { + u-boot,dm-pre-reloc; +}; + +&uart1_gpio14 { + u-boot,dm-pre-reloc; +}; -- cgit v1.2.3 From c6badda85c6f29904aa8f55c508921d38b93cc60 Mon Sep 17 00:00:00 2001 From: Kyle Evans Date: Wed, 26 Feb 2020 15:37:13 -0600 Subject: rpi: Kconfig option for initial page reservation While the nearly-universal default for the Raspberry Pi family is to use spin tables and the spin table implementation provided by the Raspberry Pi Foundation, FreeBSD and others may use a PSCI implementation instead. Accommodate these setups by allowing them to configure for more than one page to be reserved in the initial reservation. The default reservation remains as one page.
