[PATCH 1/2] riscv-cores.def: Fix description of RISCV_CORE() macro

[Christoph Muellner <christoph.muellner@vrull.eu>]

From: Christoph Müllner <christoph.muellner@vrull.eu>

The current description of RISCV_CORE() does not match the
implementation. This commit provides a fix for that.

gcc/ChangeLog:

	* config/riscv/riscv-cores.def: Fix comment.

    Before using #include to read this file, define a macro:
 
-      RISCV_CORE(CORE_NAME, ARCH, MICRO_ARCH, TUNE_INFO)
+      RISCV_CORE(CORE_NAME, ARCH, TUNE_INFO)
 
    The CORE_NAME is the name of the core, represented as a string.
-   The ARCH is the default arch of the core, represented as a string,
-   can be NULL if no default arch.
-   The MICRO_ARCH is the name of the core for which scheduling decisions
-   will be made, represented as an identifier.
-   The TUNE_INFO is the detail cost model for this core, represented as an
-   identifier, reference to riscv-tunes.def.  */
+   The ARCH is a string describing the supported RISC-V ISA (e.g. "rv32i"
+   or "rv64gc_zifencei").
+   The TUNE_INFO is a string that references the detail tuning information
+   for this core (refer to riscv_tune_info_table for possible values).  */
