From 00179319714fd2076cf81f49de357ee699672f31 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Fri, 3 Sep 2021 10:40:28 -0400 Subject: [PATCH] Revert most of the series for adding vexpress_aemv8r support Per a request from Andre Przywara and agreed with by Peter Hoyes, the vexpress aemv8r support wasn't quite ready to be merged, but the discussion had moved off list. We should keep the first patch in the series for now, but revert the rest. This reverts the following commits: e0bd6f31ce41 doc: Add documentation for the Arm vexpress board configs 30e5a449e8c7 arm: Use armv8_switch_to_el1 env to switch to EL1 b53bbca63bf4 vexpress64: Add BASER_FVP vexpress board variant 2f5b7b74903f armv8: Add ARMv8 MPU configuration logic 37a757e227cc armv8: Ensure EL1&0 VMSA is enabled Signed-off-by: Tom Rini --- arch/arm/Kconfig | 7 -- arch/arm/cpu/armv8/cache_v8.c | 96 +------------------ arch/arm/include/asm/armv8/mpu.h | 61 ------------ arch/arm/include/asm/macro.h | 17 ---- arch/arm/include/asm/system.h | 24 ----- arch/arm/lib/bootm.c | 40 +++----- board/armltd/vexpress64/Kconfig | 5 +- board/armltd/vexpress64/MAINTAINERS | 5 - board/armltd/vexpress64/vexpress64.c | 22 ----- configs/vexpress_aemv8r_defconfig | 19 ---- doc/README.semihosting | 2 +- doc/arch/arm64.rst | 3 +- doc/board/armltd/index.rst | 9 -- doc/board/armltd/vexpress64.rst | 57 ----------- doc/board/index.rst | 1 - .../{vexpress_aemv8.h => vexpress_aemv8a.h} | 58 ++++------- 16 files changed, 43 insertions(+), 383 deletions(-) delete mode 100644 arch/arm/include/asm/armv8/mpu.h delete mode 100644 configs/vexpress_aemv8r_defconfig delete mode 100644 doc/board/armltd/index.rst delete mode 100644 doc/board/armltd/vexpress64.rst rename include/configs/{vexpress_aemv8.h => vexpress_aemv8a.h} (84%) diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig index 47f094514b..50efb5e2e2 100644 --- a/arch/arm/Kconfig +++ b/arch/arm/Kconfig @@ -1185,13 +1185,6 @@ config TARGET_VEXPRESS64_BASE_FVP select PL01X_SERIAL select SEMIHOSTING -config TARGET_VEXPRESS64_BASER_FVP - bool "Support Versatile Express ARMv8r64 FVP BASE model" - select ARM64 - select DM - select DM_SERIAL - select PL01X_SERIAL - config TARGET_VEXPRESS64_JUNO bool "Support Versatile Express Juno Development Platform" select ARM64 diff --git a/arch/arm/cpu/armv8/cache_v8.c b/arch/arm/cpu/armv8/cache_v8.c index 46625675bd..3de18c7675 100644 --- a/arch/arm/cpu/armv8/cache_v8.c +++ b/arch/arm/cpu/armv8/cache_v8.c @@ -15,7 +15,6 @@ #include #include #include -#include DECLARE_GLOBAL_DATA_PTR; @@ -366,86 +365,6 @@ __weak u64 get_page_table_size(void) return size; } -static void mpu_clear_regions(void) -{ - int i; - - for (i = 0; mpu_mem_map[i].end || mpu_mem_map[i].attrs; i++) { - setup_el2_mpu_region(i, 0, 0); - } -} - -static struct mpu_region default_mpu_mem_map[] = {{0,}}; -__weak struct mpu_region *mpu_mem_map = default_mpu_mem_map; - -static void mpu_setup(void) -{ - int i; - - if (current_el() != 2) { - panic("MPU configuration is only supported at EL2"); - } - - set_sctlr(get_sctlr() & ~(CR_M | CR_WXN)); - - asm volatile("msr MAIR_EL2, %0" : : "r" MEMORY_ATTRIBUTES); - - for (i = 0; mpu_mem_map[i].end || mpu_mem_map[i].attrs; i++) { - setup_el2_mpu_region(i, - PRBAR_ADDRESS(mpu_mem_map[i].start) - | PRBAR_OUTER_SH | PRBAR_AP_RW_ANY, - PRLAR_ADDRESS(mpu_mem_map[i].end) - | mpu_mem_map[i].attrs | PRLAR_EN_BIT - ); - } - - set_sctlr(get_sctlr() | CR_M); -} - -static bool el_has_mmu(void) -{ - uint64_t id_aa64mmfr0; - asm volatile("mrs %0, id_aa64mmfr0_el1" - : "=r" (id_aa64mmfr0) : : "cc"); - uint64_t msa = id_aa64mmfr0 & ID_AA64MMFR0_EL1_MSA_MASK; - uint64_t msa_frac = id_aa64mmfr0 & ID_AA64MMFR0_EL1_MSA_FRAC_MASK; - - switch (msa) { - case ID_AA64MMFR0_EL1_MSA_VMSA: - /* - * VMSA supported in all translation regimes. - * No support for PMSA. - */ - return true; - case ID_AA64MMFR0_EL1_MSA_USE_FRAC: - /* See MSA_frac for the supported MSAs. */ - switch (msa_frac) { - case ID_AA64MMFR0_EL1_MSA_FRAC_NO_PMSA: - /* - * PMSA not supported in any translation - * regime. - */ - return true; - case ID_AA64MMFR0_EL1_MSA_FRAC_VMSA: - /* - * PMSA supported in all translation - * regimes.
