7 title: Peripheral-specific properties for a SPI bus.
10 Many SPI controllers need to add properties to peripheral devices. They could
11 be common properties like spi-max-frequency, spi-cpha, etc. or they could be
12 controller specific like delay in clock or data lines, etc. These properties
13 need to be defined in the peripheral node because they are per-peripheral and

17 2. U-Boot expects the serial console device entry to be present under /chosen
20 stdout-path = "/soc/serial@10010000:115200";
23 Without a serial console U-Boot will panic.
27 1. Add the RISC-V toolchain to your PATH.
28 2. Setup ARCH & cross compilation enviornment variable.
36 The current U-Boot port is supported in S-mode only and loaded from DRAM.
