From 239cb6feb298a31faa40b7e97ced107bf9c2f2bf Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 24 Aug 2018 13:17:50 +0100 Subject: hw/arm/mps2: Fix ID register errors on AN511 and AN385 Fix MPS2 SCC config register values for the mps2-an511 and mps2-an385 boards: * the SCC_AID bits [23:20] specify the FPGA build target board revision, and the SCC_CFG4 register specifies the actual board revision, so these should have matching values. Claim to be board revision C, consistently -- we had the revision in the wrong part of SCC_AID. * SCC_ID bits [15:4] should be the board number in hex, not decimal Signed-off-by: Peter Maydell Reviewed-by: Richard Henderson Message-id: 20180823175225.22612-1-peter.maydell@linaro.org --- hw/arm/mps2.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/hw/arm/mps2.c b/hw/arm/mps2.c index 564624629d..e3d698ba6c 100644 --- a/hw/arm/mps2.c +++ b/hw/arm/mps2.c @@ -312,7 +312,7 @@ static void mps2_common_init(MachineState *machine) sccdev = DEVICE(&mms->scc); qdev_set_parent_bus(sccdev, sysbus_get_default()); qdev_prop_set_uint32(sccdev, "scc-cfg4", 0x2); - qdev_prop_set_uint32(sccdev, "scc-aid", 0x02000008); + qdev_prop_set_uint32(sccdev, "scc-aid", 0x00200008); qdev_prop_set_uint32(sccdev, "scc-id", mmc->scc_id); object_property_set_bool(OBJECT(&mms->scc), true, "realized", &error_fatal); @@ -347,7 +347,7 @@ static void mps2_an385_class_init(ObjectClass *oc, void *data) mc->desc = "ARM MPS2 with AN385 FPGA image for Cortex-M3"; mmc->fpga_type = FPGA_AN385; mc->default_cpu_type = ARM_CPU_TYPE_NAME("cortex-m3"); - mmc->scc_id = 0x41040000 | (385 << 4); + mmc->scc_id = 0x41043850; } static void mps2_an511_class_init(ObjectClass *oc, void *data) @@ -358,7 +358,7 @@ static void mps2_an511_class_init(ObjectClass *oc, void *data) mc->desc = "ARM MPS2 with AN511 DesignStart FPGA image for Cortex-M3"; mmc->fpga_type = FPGA_AN511; mc->default_cpu_type = ARM_CPU_TYPE_NAME("cortex-m3"); - mmc->scc_id = 0x4104000 | (511 << 4); + mmc->scc_id = 0x41045110; } static const TypeInfo mps2_info = { -- cgit v1.2.3
