All, Please find the attached patch with EFI stub changes to make it work for FVP. This patch contains two fixes 1. FVP model not booting to Linux Shell with -C css.cache_state_modelled=1 flag. (arch/arm64/kernel/efi-entry.S b/arch/arm64/kernel/efi-entry.S) 2. Pre-load RAM Location support for dtb and initrd. (Format: dtb=RAM Address,Size, initrd= RAM Address,Size). (drivers/firmware/efi/libstub/efi-stub-helper.c b/drivers/firmware/efi/libstub/efi-stub-helper.c) This patch was based off of git clone http://git.linaro.org/landing-teams/working/arm/kernel.git . git checkout v4.3 If this is already taken care in EFI Stub in later kernel versions, please ignore it. If not, I thought I would at-least start a discussion here about this topic, before actually getting it in.

Generic 16550 driver

by Yehuda Yitschak

Hello everyone As part of my porting I need to use a 16550 UART port. To avoid adding a driver which already exist I am looking for an existing compatible driver. Is there a generic _MMIO_ based 16550 UART driver in EDK2 ? I only found a PCI based 16550 driver which I cant use since it don't have support for PCI Thanks ------------------- Yehuda Yitschak Marvell Semiconductor Ltd.

Assertion in Software FVP Model

by Supreeth Venkatesh

All, I am bringing up a Software model which simulates 48 ARM A72 Cores. I noticed the following assertion with UEFI in GICv3 mode. add-symbol-file /home/supven01/ashbrook_test/uefi/edk2/Build/Ashbrook_DevPlatform/DEBUG_GCC49/AARCH64/ArmPkg/Drivers/TimerDxe/TimerDxe/DEBUG/ArmTimerDxe.dll 0xFF438240 Loading driver at 0x000FF438000 EntryPoint=0x000FF438280 ArmTimerDxe.efi ASSERT /home/supven01/ashbrook_test/uefi/edk2/MdePkg/Library/BaseLib/LinkedList.c(61): List->ForwardLink != ((void *) 0) gEmbeddedTokenSpaceGuid.PcdTimerPeriod was set to "100000". However, after increasing gEmbeddedTokenSpaceGuid.PcdTimerPeriod, the assertion goes away and UEFI proceeds to load the Shell and OS. Any pointers/analysis is appreciated. Thanks, Supreeth ________________________________ -- IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.

[PATCH v3 0/4] arm64: Add Xen boot support (via fdt)

by fu.wei＠linaro.org

From: Fu Wei <fu.wei(a)linaro.org> - This adds support for the Xen boot on ARM specification for arm64. - Add and export some accessor functions of "loaded" flag and grub_linux_get_fdt function in include/grub/arm64/linux.h for xen boot. - Introduce xen_hypervisor, xen_linux, xen_initrd and xen_xsm to load different binaries for xen boot. Introduce xen_module to load common or custom module for xen boot. - This Xen boot support is a separated module for aarch64, but reuse the existing code of devicetree in linux module. - Add the support of xen_hypervisor, xen_linux and xen_initrd in util/grub.d/20_linux_xen.in - Add the introduction of all xen boot commands in docs/grub.texi - 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… Changelog: v3: create separate module for xen boot: xen_boot create separate commands for different types of module delete order-dependent for commands of xen module simplify the code v2: remove the patches which have been accepted. according to Vladimir's suggestion, change the command manes and relevant code: multiboot-->xen_hypervisor module-->xen_module improve the option parsing support for xen_hypervisor/xen_module commands. add a patch for adding xen_hypervisor/xen_module support in util/grub.d/20_linux_xen.in. update docs/grub.texi patch for the new command names. v1: The first version upstream patchset to grub-devel mailing list Fu Wei (4): arm64: Add and export some accessor functions for xen boot arm64: Add xen_boot module file * util/grub.d/20_linux_xen.in: Add support of the XEN boot on aarch64 arm64: Add the introduction of xen boot commands in docs/grub.texi docs/grub.texi | 56 ++++ grub-core/Makefile.core.def | 7 + grub-core/loader/arm64/linux.c | 13 + grub-core/loader/arm64/xen_boot.c | 685 ++++++++++++++++++++++++++++++++++++++ include/grub/arm64/linux.h | 6 +- util/grub.d/20_linux_xen.in | 16 +- 6 files changed, 779 insertions(+), 4 deletions(-) create mode 100644 grub-core/loader/arm64/xen_boot.c -- 1.8.3.1

UEFI switch to EL2

by Yehuda Yitschak

Hello everyone I am in the process of porting EDK2 to a Quad core Aarch64 based SOC. The SOC has a built-in BootROM running in EL3. When the BootROM completes loading The image it transfers control to the loaded image in EL3 to allow installing a secure monitor Since we have an on chip primary loader (i.e. BootROM) I used the 2nd stage template as a basis for my port So in my flow BootROM loads FD image to main memory and jumps to the entry point in EL3 I quickly found out however that EDK2 expects to be executed in EL2 or EL1. It was a bit surprising actually. I expected EDK2 to also act is a secure monitor and handle the PSCI calls as well. I guess I am missing something in the functional partition. To get to the point I would like to ask; - Who handles PSCI in Juno. I noticed the existence of ATF binaries such as bl0 and bl3 under Juno. Does it mean Juno works with combination of ATF and EDK2 ? - Is there a simple way to switch to EL2 using EDK2 packages. I guess the Sec part is supposed to do that, right ? Thanks ------------------- Yehuda Yitschak Marvell Semiconductor Ltd.
