From 446587a914cfa57c2ce529056a9ca2215bde7111 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 19 Feb 2021 14:45:43 +0000 Subject: hw/misc/iotkit-sysinfo.c: Implement SYS_CONFIG1 and IIDR MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit For SSE-300, the SYSINFO register block has two new registers: * SYS_CONFIG1 indicates the config for a potential CPU2 and CPU3; since the SSE-300 can only be configured with a single CPU it is always zero * IIDR is the subsystem implementation identity register; its value is set by the SoC integrator, so we plumb this in from the armsse.c code as we do with SYS_VERSION and SYS_CONFIG Signed-off-by: Peter Maydell Tested-by: Philippe Mathieu-Daudé Reviewed-by: Richard Henderson Message-id: 20210219144617.4782-11-peter.maydell@linaro.org --- hw/arm/armsse.c | 5 +++++ hw/misc/iotkit-sysinfo.c | 22 ++++++++++++++++++++++ 2 files changed, 27 insertions(+) (limited to 'hw') diff --git a/hw/arm/armsse.c b/hw/arm/armsse.c index 113a783..326e161 100644 --- a/hw/arm/armsse.c +++ b/hw/arm/armsse.c @@ -30,6 +30,7 @@ struct ARMSSEInfo { int sram_banks; int num_cpus; uint32_t sys_version; + uint32_t iidr; uint32_t cpuwait_rst; bool has_mhus; bool has_ppus; @@ -70,6 +71,7 @@ static const ARMSSEInfo armsse_variants[] = { .sram_banks = 1, .num_cpus = 1, .sys_version = 0x41743, + .iidr = 0, .cpuwait_rst = 0, .has_mhus = false, .has_ppus = false, @@ -84,6 +86,7 @@ static const ARMSSEInfo armsse_variants[] = { .sram_banks = 4, .num_cpus = 2, .sys_version = 0x22041743, + .iidr = 0, .cpuwait_rst = 2, .has_mhus = true, .has_ppus = true, @@ -950,6 +953,8 @@ static void armsse_realize(DeviceState *dev, Error **errp) } object_property_set_int(OBJECT(&s->sysinfo), "sse-version", info->sse_version, &error_abort); + object_property_set_int(OBJECT(&s->sysinfo), "IIDR", + info->iidr, &error_abort); if (!sysbus_realize(SYS_BUS_DEVICE(&s->sysinfo), errp)) { return; } diff --git a/hw/misc/iotkit-sysinfo.c b/hw/misc/iotkit-sysinfo.c index 4bd3fd4..aaa9305 100644 --- a/hw/misc/iotkit-sysinfo.c +++ b/hw/misc/iotkit-sysinfo.c @@ -30,6 +30,8 @@ REG32(SYS_VERSION, 0x0) REG32(SYS_CONFIG, 0x4) +REG32(SYS_CONFIG1, 0x8) +REG32(IIDR, 0xfc8) REG32(PID4, 0xfd0) REG32(PID5, 0xfd4) REG32(PID6, 0xfd8) @@ -70,6 +72,24 @@ static uint64_t iotkit_sysinfo_read(void *opaque, hwaddr offset, case A_SYS_CONFIG: r = s->sys_config; break; + case A_SYS_CONFIG1: + switch (s->sse_version) { + case ARMSSE_SSE300: + return 0; + break; + default: + goto bad_read; + } + break; + case A_IIDR: + switch (s->sse_version) { + case ARMSSE_SSE300: + return s->iidr; + break; + default: + goto bad_read; + } + break; case A_PID4 ...
