(https://github.com/sifive/freedom-u540-c000-bootloader/blob/master/fsbl/main.c#L428) L2 cache is of 2 MB (16 cache ways) and 1 cache way is of 128 KB. FSBL is located on the latest way of L2 cache. Therefore, FSBL can only enable the first 15 L2 cache ways to avoid corrupt itself. U-Boot proper enables all cache ways (16 cache ways) in this patch. Patch 2: Enable SiFive PWM driver This patch enables SiFive PWM driver for the SiFive Unleashed board. This series is rebase on - [v13] RISC-V SiFive FU540 support SPL This series depends on: [1] https://patchwork.ozlabs.org/patch/1275883 All these together is available for testing here [2] https://github.com/pragnesh26992/u-boot/tree/pwm Pragnesh Patel (2): riscv: sifive: fu540: enable all cache ways from U-Boot proper riscv: sifive: fu540: Enable SiFive PWM driver arch/riscv/cpu/fu540/Makefile | 1 + arch/riscv/cpu/fu540/cache.c | 53 +++++++++++++++++++++++ arch/riscv/dts/fu540-c000-u-boot.dtsi | 4 ++ arch/riscv/include/asm/arch-fu540/cache.h | 14 ++++++ board/sifive/fu540/Kconfig | 2 + board/sifive/fu540/fu540.c | 10 ++++- 6 files changed, 83 insertions(+), 1 deletion(-) create mode 100644 arch/riscv/cpu/fu540/cache.c create mode 100644 arch/riscv/include/asm/arch-fu540/cache.h -- 2.17.1 ^ permalink raw reply [flat|nested] 15+ messages in thread
