Subject: [PATCH v2 3/7] u-boot: Dynamic RISC-V ISA configuration
Date: Tue, 17 Jun 2025 18:39:40 -0500	[thread overview]
Message-ID: <1750203584-32065-4-git-send-email-mark.hatle@kernel.crashing.org> (raw)
In-Reply-To: <1750203584-32065-1-git-send-email-mark.hatle@kernel.crashing.org>

From: Mark Hatle <mark.hatle@amd.com>

Allow the risc-v TUNE_FEATURES to select specific ISA (kconfig) selections
via config fragments.

This allows the following items to be selected dynamically:

    CONFIG_RISCV_ISA_C
    CONFIG_RISCV_ISA_F
    CONFIG_RISCV_ISA_D
    CONFIG_RISCV_ISA_ZBB
    CONFIG_RISCV_ISA_A
    CONFIG_RISCV_ISA_ZICBOM
