2020-02-21ppc/pnv: Fix PCI_EXPRESS dependencyLaurent Vivier
When PHB4 bridge has been added, the dependencies to PCIE_PORT has been added to XIVE_SPAPR and indirectly to PSERIES. The build of the PowerNV machine is fine while we also build the PSERIES machine. If we disable the PSERIES machine, the PowerNV build fails because the PCI Express files are not built: /usr/bin/ld: hw/ppc/pnv.o: in function `pnv_chip_power8_pic_print_info': .../hw/ppc/pnv.c:623: undefined reference to `pnv_phb3_msi_pic_print_info' /usr/bin/ld: hw/ppc/pnv.o: in function `pnv_chip_power9_pic_print_info': .../hw/ppc/pnv.c:639: undefined reference to `pnv_phb4_pic_print_info' /usr/bin/ld: ../hw/usb/hcd-ehci-pci.o: in function `usb_ehci_pci_write_config': .../hw/usb/hcd-ehci-pci.c:129: undefined reference to `pci_default_write_config' /usr/bin/ld: ../hw/usb/hcd-ehci-pci.o: in function `usb_ehci_pci_realize': .../hw/usb/hcd-ehci-pci.c:68: undefined reference to `pci_allocate_irq' /usr/bin/ld: .../hw/usb/hcd-ehci-pci.c:72: undefined reference to `pci_register_bar' /usr/bin/ld: ../hw/usb/hcd-ehci-pci.o:(.data.rel+0x50): undefined reference to `vmstate_pci_device' This patch fixes the problem by adding needed dependencies to POWERNV.

into staging RISC-V Patches for the 5.0 Soft Freeze, Part 2 This is a fairly light-weight pull request, but I wanted to send it out to avoid the Goldfish stuff getting buried as the next PR should contain the H extension implementation. As far as this PR goes, it contains: * The addition of syscon device tree nodes for reboot and poweroff, which allows Linux to control QEMU without an additional driver. The existing device was already compatible with the syscon interface. * A fix to our GDB stub to avoid confusing XLEN and FLEN, specifically useful for rv32id-based systems. * A device emulation for the Goldfish RTC device, a simple memory-mapped RTC. * The addition of the Goldfish RTC device to the RISC-V virt board. This passes "make check" and boots buildroot for me. # gpg: Signature made Mon 10 Feb 2020 21:28:04 GMT # gpg: using RSA key 2B3C3747446843B24A943A7A2E1319F35FBB1889 # gpg: issuer "palmer@dabbelt.com" # gpg: Good signature from "Palmer Dabbelt <palmer@dabbelt.com>" [unknown] # gpg: aka "Palmer Dabbelt <palmer@sifive.com>" [unknown] # gpg: aka "Palmer Dabbelt <palmerdabbelt@google.com>" [unknown] # gpg: WARNING: This key is not certified with a trusted signature! # gpg: There is no indication that the signature belongs to the owner. # Primary key fingerprint: 00CE 76D1 8349 60DF CE88 6DF8 EF4C A150 2CCB AB41 # Subkey fingerprint: 2B3C 3747 4468 43B2 4A94 3A7A 2E13 19F3 5FBB 1889 * remotes/palmer/tags/riscv-for-master-5.0-sf2: MAINTAINERS: Add maintainer entry for Goldfish RTC riscv: virt: Use Goldfish RTC device hw: rtc: Add Goldfish RTC device riscv: Separate FPU register size from core register size in gdbstub [v2] riscv/virt: Add syscon reboot and poweroff DT nodes Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2020-02-13hw/arm/raspi: Use BCM2708 machine type with pre Device Tree kernelsPhilippe Mathieu-Daudé
When booting without device tree, the Linux kernels uses the $R1 register to determine the machine type. The list of values is registered at [1]. There are two entries for the Raspberry Pi: - https://www.arm.linux.org.uk/developer/machines/list.php?mid=3138 name: MACH_TYPE_BCM2708 value: 0xc42 (3138) status: Active, not mainlined date: 15 Oct 2010 - https://www.arm.linux.org.uk/developer/machines/list.php?mid=4828 name: MACH_TYPE_BCM2835 value: 4828 status: Active, mainlined date: 6 Dec 2013 QEMU always used the non-mainlined type MACH_TYPE_BCM2708. The value 0xc43 is registered to 'MX51_GGC' (processor i.MX51), and 0xc44 to 'Western Digital Sharespace NAS' (processor Marvell 88F5182). The Raspberry Pi foundation bootloader only sets the BCM2708 machine type, see [2] or [3]: 133 9: 134 mov r0, #0 135 ldr r1, =3138 @ BCM2708 machine id 136 ldr r2, atags @ ATAGS 137 bx r4 U-Boot only uses MACH_TYPE_BCM2708 (see [4]): 25 /* 26 * 2835 is a SKU in a series for which the 2708 is the first or primary SoC, 27 * so 2708 has historically been used rather than a dedicated 2835 ID. 28 * 29 * We don't define a machine type for bcm2709/bcm2836 since the RPi Foundation 30 * chose to use someone else's previously registered machine ID (3139, MX51_GGC) 31 * rather than obtaining a valid ID:-/ 32 * 33 * For the bcm2837, hopefully a machine type is not needed, since everything 34 * is DT. 35 */ While the definition MACH_BCM2709 with value 0xc43 was introduced in a commit described "Add 2709 platform for Raspberry Pi 2" out of the mainline Linux kernel, it does not seem used, and the platform is introduced with Device Tree support anyway (see [5] and [6]). Remove the unused values (0xc43 introduced in commit 1df7d1f9303aef "raspi: add raspberry pi 2 machine" and 0xc44 in commit bade58166f4 "raspi: Raspberry Pi 3 support"), keeping only MACH_TYPE_BCM2708.
