2024-03-06riscv: dts: Move BUILTIN_DTB_SOURCE to common KconfigYangyu Chen1-1/+1
The BUILTIN_DTB_SOURCE was only configured for K210 before. Since SOC_BUILTIN_DTB_DECLARE was removed at commit d5805af9fe9f ("riscv: Fix builtin DTB handling") from patch [1], the kernel cannot choose one of the dtbs from then on and always take the first one dtb to use. Then, another commit 0ddd7eaffa64 ("riscv: Fix BUILTIN_DTB for sifive and microchip soc") from patch [2] supports BUILTIN_DTB_SOURCE for other SoCs. However, this feature will only work if the Kconfig we use links the dtb we expected in the first place as mentioned in the thread [3]. Thus, a config BUILTIN_DTB_SOURCE is needed for all SoCs to choose one dtb to use. For some considerations, this patch also removes default y if XIP_KERNEL for BUILTIN_DTB, as this requires setting a proper dtb to use on the BUILTIN_DTB_SOURCE, else the kernel with XIP but does not set BUILTIN_DTB_SOURCE or unselect BUILTIN_DTB will not boot. Also, this patch removes the default dtb string for k210 from Kconfig to nommu_k210_defconfig and nommu_k210_sdcard_defconfig to avoid complex Kconfig settings for other SoCs in the future.

Sipeed's Lichee Pi 4A development board uses Lichee Module 4A core module which is powered by T-HEAD's TH1520 SoC. Add minimal device tree files for the core module and the development board. Support basic uart/gpio/dmac drivers, so supports booting to a basic shell. Signed-off-by: Jisheng Zhang <[email protected]> Signed-off-by: Conor Dooley <[email protected]>
2023-01-27riscv: dts: allwinner: Add MangoPi MQ devicetreeSamuel Holland1-0/+1
The MangoPi MQ is a tiny SBC built around the Allwinner D1s. Its onboard peripherals include two USB Type-C ports (1 device, 1 host) and RTL8189FTV WLAN. A MangoPi MQ-R variant of the board also exists. The MQ-R has a different form factor, but the onboard peripherals are the same. Most D1 and D1s boards use a similar power tree, with the 1.8V rail powered by the SoC's internal LDOA, analog domains powered by ALDO, and the rest of the board powered by always-on fixed regulators. To avoid duplication, factor out the regulator information that is common across boards. The board also exposes GPIO Port E via a FPC connector, which can support either a camera or an RMII Ethernet PHY. The additional regulators supply that connector.

Enable the minimal blocks required for booting the Renesas RZ/Five SMARC EVK with initramfs. Below are the blocks which are enabled: - CPG - CPU0 - DDR (memory regions) - PINCTRL - PLIC - SCIF0 As we are reusing the RZ/G2UL SoC base DTSI [0], RZ/G2UL SMARC SoM [1] and carrier [2] board DTSIs which enables almost all the blocks supported by the RZ/G2UL SMARC EVK and whereas on RZ/Five SoC we will be gradually enabling the blocks hence the aliases for ETH/I2C are deleted and rest of the IP blocks are marked as disabled/deleted.

2021-01-07riscv: Fix builtin DTB handlingDamien Le Moal1-1/+1
All SiPeed K210 MAIX boards have the exact same vendor, arch and implementation IDs, preventing differentiation to select the correct device tree to use through the SOC_BUILTIN_DTB_DECLARE() macro. This result in this macro to be useless and mandates changing the code of the sysctl driver to change the builtin device tree suitable for the target board. Fix this problem by removing the SOC_BUILTIN_DTB_DECLARE() macro since it is used only for the K210 support. The code searching the builtin DTBs using the vendor, arch an implementation IDs is also removed. Support for builtin DTB falls back to the simpler and more traditional handling of builtin DTB using the CONFIG_BUILTIN_DTB option, similarly to other architectures.

2020-05-18riscv: K210: Add a built-in device treePalmer Dabbelt1-0/+2
The K210's bootloader does not provide a device tree. Give the ability to providea builtin one with the SOC_KENDRYTE_K210_BUILTIN_DTB option. If selected, this option result in the definition of a builtin DTB entry in the k210 sysctl driver. If defined, the builtin DTB entry points to the default k210.dts device tree file and is keyed with the vendor ID 0x4B5, the arch ID 0xE59889E6A5A04149 ("Canaan AI" in UTF-8 coded Chinese) and the impl ID 0x4D41495832303030 ("MAIX200"). These values are reported by the SiPEED MAIXDUINO board, the SiPEED MAIX Go board and the SiPEED Dan Dock board.
