/*
* The FreeRTOS kernel's RISC-V port is split between the the code that is
* common across all currently supported RISC-V chips (implementations of the
* RISC-V ISA), and code that tailors the port to a specific RISC-V chip:
*
* + FreeRTOS\Source\portable\GCC\RISC-V-RV32\portASM.S contains the code that
* is common to all currently supported RISC-V chips. There is only one
* portASM.S file because the same file is built for all RISC-V target chips.
*
* + Header files called freertos_risc_v_chip_specific_extensions.h contain the
* code that tailors the FreeRTOS kernel's RISC-V port to a specific RISC-V
* chip. There are multiple freertos_risc_v_chip_specific_extensions.h files
* as there are multiple RISC-V chip implementations.
*
* !!!NOTE!!!
* TAKE CARE TO INCLUDE THE CORRECT freertos_risc_v_chip_specific_extensions.h
* HEADER FILE FOR THE CHIP IN USE. This is done using the assembler's (not the
* compiler's!) include path. For example, if the chip in use includes a core
* local interrupter (CLINT) and does not include any chip specific register
* extensions then add the path below to the assembler's include path:
* FreeRTOS\Source\portable\GCC\RISC-V-RV32\chip_specific_extensions\RV32I_CLINT_no_extensions
