From 35509737c8f958944e059d501255a0bf18361ba0 Mon Sep 17 00:00:00 2001 From: Dmitry Osipenko Date: Fri, 13 Mar 2020 12:01:04 +0300 Subject: ARM: tegra: Correct PL310 Auxiliary Control Register initialization The PL310 Auxiliary Control Register shouldn't have the "Full line of zero" optimization bit being set before L2 cache is enabled. The L2X0 driver takes care of enabling the optimization by itself. This patch fixes a noisy error message on Tegra20 and Tegra30 telling that cache optimization is erroneously enabled without enabling it for the CPU: L2C-310: enabling full line of zeros but not enabled in Cortex-A9 Cc: Signed-off-by: Dmitry Osipenko Tested-by: Nicolas Chauvet Signed-off-by: Thierry Reding --- arch/arm/mach-tegra/tegra.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'arch/arm/mach-tegra') diff --git a/arch/arm/mach-tegra/tegra.c b/arch/arm/mach-tegra/tegra.c index f1ce2857a251..b620b0651157 100644 --- a/arch/arm/mach-tegra/tegra.c +++ b/arch/arm/mach-tegra/tegra.c @@ -107,8 +107,8 @@ static const char * const tegra_dt_board_compat[] = { }; DT_MACHINE_START(TEGRA_DT, "NVIDIA Tegra SoC (Flattened Device Tree)") - .l2c_aux_val = 0x3c400001, - .l2c_aux_mask = 0xc20fc3fe, + .l2c_aux_val = 0x3c400000, + .l2c_aux_mask = 0xc20fc3ff, .smp = smp_ops(tegra_smp_ops), .map_io = tegra_map_common_io, .init_early = tegra_init_early, -- cgit v1.2.3
