soc: riscv32: add RV32M1 SoC as openisa_rv32m1 The OpenISA RV32M1 SoC has four CPU cores. Two of these are RISC-V 32-bit cores, which are named "RI5CY" and "ZERO-RISCY". (The other two cores are ARM Cortex-M0+ and -M4.) This patch adds basic SoC enablement for the RISC-V cores: - basic dtsi, to be extended as additional drivers are added - SoC definition in soc/riscv32/openisa_rv32m1 for RI5CY / ZERO-RISCY - system timer driver for RI5CY, based on LPTMR0 peripheral The timer driver will be generalized a bit soon once proper multi-level interrupt support is available. Emphasis is on supporting the RI5CY core as the more capable of the two; the ZERO-RISCY SoC definitions are a good starting point, but additional work setting up a dtsi and initial drivers is needed to support that core.

riscv: linker.ld: Port vector table to zephyr_linker_sources() Put it in its own linker file snippet. Signed-off-by: Øyvind Rønningstad <oyvind.ronningstad@nordicsemi.no>

extensions.cmake: Replace TEXT_START with ROM_START In zephyr_linker_sources(). This is done since the point of the location is to place things at given offsets. This can only be done consistenly if the linker code is placed into the _first_ section. All uses of TEXT_START are replaced with ROM_START. ROM_START is only supported in some arches, as some arches have several custom sections before text. These don't currently have ROM_START or TEXT_START available, but that could be added with a bit of refactoring in their linker script. No SORT_KEYs are changed. This also fixes an error introduced when TEXT_START was added, where TEXT_SECTION_OFFSET was applied to riscv's common linker.ld instead of to openisa_rv32m1's specific linker.ld.
