It features dual Cortex-A35 cores with GICv3, a Denali\nDDR memory controller, Cadence GEM Ethernet (SGMII), and reuses several\nGXP IP blocks (timer, SPI, I2C).\n\nThe existing ARCH_GXP Kconfig symbol is renamed to ARCH_HPE to serve as\nan umbrella for both the GXP (ARMv7) and GSC (ARMv8) SoC variants,\nselected via a choice menu under mach-hpe.\n\nNew drivers:\n- Watchdog (drivers/watchdog/gsc_wdt.c)\n- Memory-mapped virtual EEPROM for VPD (drivers/misc/gsc_mem_eeprom.c)\n- Cadence GEM support added to the existing MACB driver\n\nBoard support includes DRAM sizing from the Denali memory controller,\nMAC address provisioning from VPD EEPROM, FDT fixups for network\nconfiguration, shared Ethernet/DisplayPort PHY initialization, and a\nserver_id command for reading server identification from the CPLD.\n\nNotes:\n- The server_id command (patch 7) is hardware-specific and reads from\n GSC CPLD registers, so no sandbox test is included.\n- MAINTAINERS warnings in patches 1-8 are resolved by patch 9.\n\nBased on v2026.04-rc4 (ba7bf918dafcd093ad733b07ba490baeb20cf5da).\nTested: both gxp_defconfig and gsc_defconfig build cleanly.\n\nSigned-off-by: Jorge Cisneros \n---\nJorge Cisneros (9):\n arm: hpe: Rename ARCH_GXP to ARCH_HPE and add GSC SoC choice\n arm: hpe: Add GSC SoC support\n arm: dts: Add HPE GSC device tree\n watchdog: Add HPE GSC watchdog driver\n misc: Add HPE GSC memory-mapped EEPROM driver\n net: macb: Add HPE GSC GEM Ethernet support\n board: hpe: Add GSC board support\n configs: Add gsc_defconfig for HPE GSC SoC\n MAINTAINERS: Add HPE GSC files and maintainer\n\n MAINTAINERS | 8 +-\n arch/arm/Kconfig | 9 +-\n arch/arm/Makefile | 2 +-\n arch/arm/dts/hpe-gsc.dts | 146 ++++++++\n arch/arm/include/asm/arch-gsc/clk.h | 14 +\n arch/arm/mach-hpe/Kconfig | 33 ++\n arch/arm/mach-hpe/Makefile | 1 +\n arch/arm/mach-hpe/gsc/Kconfig | 27 ++\n arch/arm/mach-hpe/gsc/Makefile | 1 +\n arch/arm/mach-hpe/gsc/reset.c | 19 +\n arch/arm/mach-hpe/gxp/Kconfig | 2 +-\n board/hpe/gsc/Kconfig | 18 +\n board/hpe/gsc/Makefile | 3 +\n board/hpe/gsc/common-phy-wrapper-addresses.h | 86 +++++\n board/hpe/gsc/common-phy.c | 296 +++++++++++++++\n board/hpe/gsc/common-phy.h | 8 +\n board/hpe/gsc/gsc.env | 9 +\n board/hpe/gsc/gsc_board.c | 538 +++++++++++++++++++++++++++\n board/hpe/gsc/server_id.c | 51 +++\n configs/gsc_defconfig | 88 +++++\n configs/gxp_defconfig | 2 +-\n drivers/misc/Kconfig | 7 +\n drivers/misc/Makefile | 1 +\n drivers/misc/gsc_mem_eeprom.c | 118 ++++++\n drivers/net/macb.c | 17 +\n drivers/watchdog/Kconfig | 7 +\n drivers/watchdog/Makefile | 1 +\n drivers/watchdog/gsc_wdt.c | 110 ++++++\n include/configs/gsc.h | 25 ++\n 29 files changed, 1640 insertions(+), 7 deletions(-)\n---\nbase-commit: ba7bf918dafcd093ad733b07ba490baeb20cf5da\nchange-id: 20260408-hpe-gsc-upstream-369c5ee59c0a\n\nBest regards,\n-- \nJorge Cisneros "}
