[PATCH 0/5]arm64: Add multiboot support (via fdt) for Xen boot

by Fu Wei

- This multiboot support is built into linux module for aarch64. - The implementation for Xen is following <Multiboot on ARM Specification>: http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions/Multiboot and xen/docs/misc/arm/device-tree/booting.txt in Xen source code. - The example of this support is <How to boot Xen with GRUB on AArch64 the Foundation FVP model> https://wiki.linaro.org/LEG/Engineering/Grub2/Xen_booting_on_Foundation_FVP… - This adds support for the Xen Multiboot on ARM specification for arm64, enabling config file portability across the architectures. - The multiboot command is currently x86-only, so reusing these command names should not conflict with any future additions of ARM support to multiboot2. - The reason of adding this functionality to the existing "linux" module rather than "multiboot(2)" (1)multiboot is x86 only (2)Multiboot is added to "linux" module because it reuses existing code. - Some changes in original linux module code Move some #define from grub-core/loader/arm64/linux.c to include/grub/arm64/linux.h Make some shared functions for multiboot.c Remove "loaded" checking in the grub_cmd_devicetree of linux.c - Add grub_fdt_set_reg64 macro into fdt.h header file for inserting "reg" properiy, while #address-cells = <0x2> and #size-cells = <0x2> - Add the introduction of multiboot/module command in docs/grub.texi This multiboot support will be built in linux module for aarch64, and can not be used alone. docs/grub.texi | 10 + grub-core/Makefile.core.def | 1 + grub-core/loader/arm64/linux.c | 72 ++--- grub-core/loader/arm64/multiboot.c | 593 +++++++++++++++++++++++++++++++++++++ include/grub/arm64/linux.h | 11 + include/grub/arm64/multiboot.h | 115 +++++++ include/grub/fdt.h | 12 + 7 files changed, 778 insertions(+), 36 deletions(-) create mode 100644 grub-core/loader/arm64/multiboot.c create mode 100644 include/grub/arm64/multiboot.h Signed-off-by: Fu Wei <fu.wei(a)linaro.org> Reviewed-by: Leif Lindholm <leif.lindholm(a)linaro.org> -- 1.8.3.1

Hi Leif, Is the beaglebone black EDK2 port in reasonable shape? If so I want to try Ard's new 32 bit EFI stub update a try on that. Thanks, Roy

[PATCH 0/8] Updated EFI support for 32-bit ARM

by Ard Biesheuvel

Hi all, Yesterday and this morning, I had a go at bringing the 32-bit ARM EFI support in line with the current arm64 upstream code. I have reshuffled a lot of Roy's code, mainly so that the remaining delta against the ARM tree is as small as possible, and keeps out of existing early init code as much as possible. I have not reused any of the existing 32-bit runtime services code. I did not use the early ioremap support but instead refactored the existing init code lightly so that we can use two adjacent fixmap slots instead. This mostly works, but there are (at least) two issues that need resolving: - LPAE support builds but doesn't run - the EFI page tables are clobbered at some point in the execution -> note in the log below that the RTC efi is read successfully once, but later on (when invoked by hwclock from userland), the page table entries have been cleared I don't intend to burn a lot of time on this but it may be worthwile to run this on a model (with better watchpoint support) to figure out what is going on with the page tables. Not today though .... Ard Biesheuvel (7): efi: avoid initialized .data in the EFI stub efi: build efi_config_init() only if CONFIG_EARLY_IOREMAP arm64/efi: split off EFI init and runtime code for reuse by 32-bit ARM arm64/efi: refactor EFI init and runtime code for reuse by 32-bit ARM ARM: move fixmap init before memblock init and use static allocation ARM: split off core code from create_mapping() for EFI reuse ARM: add UEFI support Roy Franz (1): ARM: add strstr and strncmp to compressed string.c arch/arm/Kconfig | 19 ++ arch/arm/boot/compressed/.gitignore | 2 + arch/arm/boot/compressed/Makefile | 18 +- arch/arm/boot/compressed/efi-header.S | 141 +++++++++++ arch/arm/boot/compressed/efi-stub.c | 89 +++++++ arch/arm/boot/compressed/head.S | 66 ++++- arch/arm/boot/compressed/string.c | 43 ++++ arch/arm/include/asm/efi.h | 135 ++++++++++ arch/arm/include/asm/fixmap.h | 4 + arch/arm/include/asm/mach/map.h | 1 + arch/arm/kernel/setup.c | 5 + arch/arm/mm/mmu.c | 68 +++-- arch/arm64/include/asm/efi.h | 29 +++ arch/arm64/kernel/efi.c | 330 +------------------------ drivers/firmware/efi/Makefile | 4 + drivers/firmware/efi/arm-init.c | 212 ++++++++++++++++ drivers/firmware/efi/arm-runtime.c | 142 +++++++++++ drivers/firmware/efi/efi.c | 2 + drivers/firmware/efi/libstub/efi-stub-helper.c | 8 +- 19 files changed, 952 insertions(+), 366 deletions(-) create mode 100644 arch/arm/boot/compressed/efi-header.S create mode 100644 arch/arm/boot/compressed/efi-stub.c create mode 100644 arch/arm/include/asm/efi.h create mode 100644 drivers/firmware/efi/arm-init.c create mode 100644 drivers/firmware/efi/arm-runtime.c -- EFI stub: Booting Linux Kernel...

[PATCHv2 0/2] Add SPCR/DBG2 tables for kernel testing/debug

by Graeme Gregory

These patches add the DBG2/SPCR tables for FVP/Juno for kernel testing. They allow a kernel to find a serial console without console= line. They have been tested using the Redhat patches for SPCR support which are work in progress! Thanks Changes since v1 Ryan pointed out I had used RTSM in the JUNO tables - fixed.

UEFI on KVM fails to start on juno on cortex-a57 cluster

by Riku Voipio

Hi, It appears on juno, I can start kvm with UEFI only on cortex-a53 cores: taskset -c 0 qemu-system-aarch64 -m 1024 -cpu host -M virt -bios QEMU_EFI.fd -enable-kvm -nographic -> works: UEFI Interactive Shell v2.0 taskset -c 1 qemu-system-aarch64 -m 1024 -cpu host -M virt -bios QEMU_EFI.fd -enable-kvm -nographic -> hangs at cpu spinning 100% ... Qemu and kernel are latest mainline, kvm from last months Ĺinaro release. According to cpuinfo cores 0 and 3-5 are a53 and 1-2 are a57.

by jayanthi annadurai

Hi, I want to boot Linux from NOR flash. I see that ARM juno board is using BootMonFs file system on NOR flash. How to create BootMonFs on NOR flash? Is there any other option available to use NOR as a boot device? Thank you, Jayanthi
