31 * The FreeRTOS kernel's RISC-V port is split between the the code that is
\r
32 * common across all currently supported RISC-V chips (implementations of the
\r
33 * RISC-V ISA), and code which tailors the port to a specific RISC-V chip:
\r
35 * + The code that is common to all RISC-V chips is implemented in
\r
36 * FreeRTOS\Source\portable\GCC\RISC-V-RV32\portASM.S. There is only one
\r
37 * portASM.S file because the same file is used no matter which RISC-V chip is
\r
40 * + The code that tailors the kernel's RISC-V port to a specific RISC-V
\r
41 * chip is implemented in freertos_risc_v_port_specific_extensions.h. There
\r
42 * is one freertos_risc_v_port_specific_extensions.h that can be used with any
\r
43 * RISC-V chip that both includes a standard CLINT and does not add to the
\r
44 * base set of RISC-V registers. There are additional
\r
45 * freertos_risc_v_port_specific_extensions.h files for RISC-V implementations
\r
46 * that do not include a standard CLINT or do add to the base set of RISC-V
\r
49 * CARE MUST BE TAKEN TO INCLDUE THE CORRECT
\r
50 * freertos_risc_v_port_specific_extensions.h HEADER FILE FOR THE CHIP
\r
51 * IN USE. To include the correct freertos_risc_v_port_specific_extensions.h
\r
52 * header file ensure the path to the correct header file is in the assembler's
\r
55 * This freertos_risc_v_port_specific_extensions.h is for use on RISC-V chips
\r
56 * that include a standard CLINT and do not add to the base set of RISC-V
