All POWER systems have an architecturally defined decrementer and timestamp counter. On such systems, the LiteX timer peripheral is redundant, but the LiteX BIOS assumes it is present on all SoCs. Add a minimal interface from the LiteX BIOS code to the POWER internal decrementer for SoCs without the LiteX timer peripheral.

Add support for xcompiler on Alpine 3.13
-
Benjamin Henrion authored
Problem: xcompiler on Alpine 3.13 was not found Solution is to add "riscv-none-elf-gcc": 1. Add Edge to your repositories: $ echo -e "http://dl-cdn.alpinelinux.org/alpine/edge/main\nhttp://dl-cdn.alpinelinux.org/alpine/edge/testing\nhttp://dl-cdn.alpine linux.org/alpine/edge/community" >> /etc/apk/repositories $ apk update $ apk add gcc-riscv-none-elf 2. The xcompiler should be found at: $ which riscv-none-elf-gcc /usr/bin/riscv-none-elf-gcc

soc: Add init_rom to initialize ROM and contents and with auto_size option (enable by default) to reduce ROM size to length of contents when in Read Only mode. This ensures the integrated ROM is reduced to minimal size before build and avoid having to adjust it manually with --integrated-rom-size on targets.
