However, on real hardware, the SSP begins in a powered-off\nstate. The typical boot sequence involves the PSP powering up first, loading\nthe SSP firmware binary into shared memory via DRAM remap, and then releasing\nthe SSP reset and enabling it through SCU control registers.\n\nTo more accurately model this behavior in QEMU, this commit sets the\n\"start-powered-off\" property for the SSP's ARMv7M core. This change ensures\nthe SSP remains off until explicitly enabled via the SCU, simulating the\nreal-world flow where the PSP controls SSP boot through SCU interaction.\n\nSigned-off-by: Jamin Lin <jamin_lin@aspeedtech.com>\n---\n hw/arm/aspeed_ast27x0-ssp.c | 7 +++++++\n 1 file changed, 7 insertions(+)", "diff": "diff --git a/hw/arm/aspeed_ast27x0-ssp.c b/hw/arm/aspeed_ast27x0-ssp.c\nindex 9a2079668b..edfcf1badb 100644\n--- a/hw/arm/aspeed_ast27x0-ssp.c\n+++ b/hw/arm/aspeed_ast27x0-ssp.c\n@@ -166,6 +166,13 @@ static void aspeed_soc_ast27x0ssp_realize(DeviceState *dev_soc, Error **errp)\n qdev_connect_clock_in(armv7m, \"cpuclk\", s->sysclk);\n object_property_set_link(OBJECT(&a->armv7m), \"memory\",\n OBJECT(s->memory), &error_abort);\n+ /*\n+ * The SSP starts in a powered-down state and can be powered up\n+ * by setting the SSP Control Register through the SCU\n+ * (System Control Unit)\n+ */\n+ object_property_set_bool(OBJECT(&a->armv7m), \"start-powered-off\", true,\n+ &error_abort);\n sysbus_realize(SYS_BUS_DEVICE(&a->armv7m), &error_abort);\n \n /* SDRAM */\n", "prefixes": [ "v4", "03/21" ] }
