System RDL support
This PR introduces initial support for generating SoC configuration registers using the SystemRDL tool. The goal is to replace the existing
reggentool withSystemRDL.🆕 Added
rdl: Therdlfolder contains all the RDL files needed to correctly generate the SoC address map. It includes the SoC control registers (chimera_regs) as well as the top-level address map (chimera.rdl), which is used to generate the C-header with the full address map and helper structs.chimera_top_wrapper: The top-level wrapper has been updated to convert the internal Cheshire register protocol to the APB protocol used to connect to the SystemRDL-generated registers.chimera_addrmap.h: With the C-header support of SystemRDL, a new header file containing the full Chimera SoC address map has been generated.offload.c: The offload helper functions have been refactored to use the new generated structs.chimera.mk: The makefile now includes a target to regenerate the SoC registers if necessary.sw.mk: A new target has been introduced to regenerate the address map header.
