Initial patch based on [1] to support yosemite v4 bmc emulation. The goal of this machine support is to support OpenBMC development.
Reference linux devicetree from openbmc linux is [2]. Status: - Enclosure FRU: showing up - Management Board FRU: showing up - Blade Board FRU: showing up - Blade Board sensors: not implemented - Blade Chassis FRU: showing up - Fan Board FRU: both showing up - Fan Board sensors: supported Overall the emulation is incomplete but already helpful in development and testing. The focus of this initial support is on the FRU eeproms and fanboard sensors. Tested: booted an OpenBMC image for yosemite4 target. Tested: functional test (see [5] for the image) passed. ``` export QEMU_TEST_QEMU_BINARY=qemu-system-arm ./build/run tests/functional/arm/test_aspeed_fby4.py TAP version 13 ok 1 test_aspeed_fby4.YosemiteV4Machine.test_arm_ast2600_yosemitev4_openbmc 1..1 ``` References: [1] https://github.com/9elements/qemu/commit/32139f913c2bd0ebe4bd26c46765861f6f9f2d49 [2] arch/arm/boot/dts/aspeed/aspeed-bmc-facebook-yosemite4.dts [3] https://github.com/legoater/qemu-aspeed-boot/pull/5 Cc: "Cédric Le Goater" <[email protected]> (maintainer:ASPEED BMCs) Cc: Peter Maydell <[email protected]> (maintainer:ASPEED BMCs) Cc: Steven Lee <[email protected]> (reviewer:ASPEED BMCs) Cc: Troy Lee <[email protected]> (reviewer:ASPEED BMCs) Cc: Jamin Lin <[email protected]> (reviewer:ASPEED BMCs) Cc: Kane Chen <[email protected]> (reviewer:ASPEED BMCs) Cc: Andrew Jeffery <[email protected]> (reviewer:ASPEED BMCs) Cc: Joel Stanley <[email protected]> (reviewer:ASPEED BMCs) Cc: [email protected] (open list:ASPEED BMCs) Cc: [email protected] (open list:All patches CC here) Signed-off-by: Alexander Hansen <[email protected]> --- hw/arm/aspeed_ast2600_fby4.c | 289 +++++++++++++++++++++++ hw/arm/meson.build | 1 + tests/functional/arm/meson.build | 2 + tests/functional/arm/test_aspeed_fby4.py | 44 ++++ 4 files changed, 336 insertions(+) create mode 100644 hw/arm/aspeed_ast2600_fby4.c create mode 100755 tests/functional/arm/test_aspeed_fby4.py diff --git a/hw/arm/aspeed_ast2600_fby4.c b/hw/arm/aspeed_ast2600_fby4.c new file mode 100644 index 0000000000..284f64e3f3 --- /dev/null +++ b/hw/arm/aspeed_ast2600_fby4.c @@ -0,0 +1,289 @@ +/* + * Yosemite V4 + * + * Copyright 2026 9elements. + * + * SPDX-License-Identifier: GPL-2.0-or-later + */ + +#include "qemu/osdep.h" +#include "qapi/error.h" +#include "hw/arm/machines-qom.h" +#include "hw/arm/aspeed.h" +#include "hw/arm/aspeed_soc.h" +#include "hw/nvram/eeprom_at24c.h" +#include "hw/sensor/tmp105.h" +#include "hw/sensor/max31790.h" +#include "hw/sensor/max11615.h" +#include "hw/sensor/adc128d818.h" +#include "hw/i2c/i2c_mux_pca954x.h" +#include "hw/gpio/pca9552.h" +#include "system/reset.h" + +#define FBY4_BMC_RAM_SIZE ASPEED_RAM_SIZE(2 * GiB) + +/* START OF EEPROM CONTENTS */ + +/* + *./frugen -s board.mfg="Wiwynn" \ + * --set board.pname="Fan Board FSC-MAX ADC-TI LED-NXP EFUSE-MAX" \ + * --set text:board.pn="BRD-PN-345" \ + * --board-date "10/1/2017 12:58:00" \ + * --set board.serial="123456" \ + * --set product.pname="Yosemite V4" \ + * --set product.mfg="Wiwynn" \ + * --set product.ver="v1.1" \ + * --set product.serial="123456" \ + * --set product.atag="PLACEHOLDER" \ + * --set product.custom="Fanboard Custom1" \ + * --set product.custom.1="Fanboard Custom2" \ + * --set text:product.pn="PN-345" \ + * fru-yv4-fanboard.bin + */ +/* EM Config: yosemite4_fanboard_fsc_max_adc_ti_led_nxp_ons_efuse_max.json */ +/* Yosemite4 fan board */ +static const uint8_t fru_yv4_fanboard_bin[] = { + 0x01, 0x00, 0x00, 0x01, 0x0b, 0x00, 0x00, 0xf3, 0x01, 0x0a, 0x19, 0xce, + 0xc2, 0xa8, 0xc6, 0x57, 0x69, 0x77, 0x79, 0x6e, 0x6e, 0xea, 0x46, 0x61, + 0x6e, 0x20, 0x42, 0x6f, 0x61, 0x72, 0x64, 0x20, 0x46, 0x53, 0x43, 0x2d, + 0x4d, 0x41, 0x58, 0x20, 0x41, 0x44, 0x43, 0x2d, 0x54, 0x49, 0x20, 0x4c, + 0x45, 0x44, 0x2d, 0x4e, 0x58, 0x50, 0x20, 0x45, 0x46, 0x55, 0x53, 0x45, + 0x2d, 0x4d, 0x41, 0x58, 0x85, 0x91, 0x34, 0x51, 0x95, 0x05, 0xca, 0x42, + 0x52, 0x44, 0x2d, 0x50, 0x4e, 0x2d, 0x33, 0x34, 0x35, 0xc0, 0xc1, 0x00, + 0x00, 0x00, 0x00, 0xdb, 0x01, 0x09, 0x19, 0xc6, 0x57, 0x69, 0x77, 0x79, + 0x6e, 0x6e, 0xcb, 0x59, 0x6f, 0x73, 0x65, 0x6d, 0x69, 0x74, 0x65, 0x20, + 0x56, 0x34, 0xc6, 0x50, 0x4e, 0x2d, 0x33, 0x34, 0x35, 0xc4, 0x76, 0x31, + 0x2e, 0x31, 0x85, 0x91, 0x34, 0x51, 0x95, 0x05, 0x89, 0x30, 0x1b, 0x8e, + 0x25, 0xfa, 0xb2, 0x64, 0x29, 0x03, 0xc0, 0xd0, 0x46, 0x61, 0x6e, 0x62, + 0x6f, 0x61, 0x72, 0x64, 0x20, 0x43, 0x75, 0x73, 0x74, 0x6f, 0x6d, 0x32, + 0xc1, 0x00, 0x00, 0x9d +};
