[feature/linker_cleanup] Clean up the sw + linking flow #24

Open MaistoV opened 6 days ago

MaistoV commented 6 days ago

Currently, each sw app uses aits own linker script and not the one config-generated, which is just a stub.

We should have a/some common .ld(s) in a given folder, config-generated, which all SoC apps refer to.
The physical addresses of peripherals should come from linker-defined symbols, not hardcoded in headers. Alternatively, we should define a SoC header

From meeting minutes, this task also involves:

compiler prefix analysis, in preparation for RV64 and Linux
unification of linker scripts
restructure sw/SoC/ directory
add doc for sw flow
add sw/Makefile + sw/SoC/Makefile control of all sub-apps

Optionally, also:

set num master and slaves in uninasoc_pkg.sv with macros from config flow (axi_config.mk)
automatically connect xbar masters/slaves fom config flow

In addition to this, we should also understand how to deal with external libraries, wether they are different repos or not. Also, we should decide for a structure of the SoC sw directory.
