[PATCH] xen/arm64: check XSM Magic and Signature from the second unknown module.

by fu.wei＠linaro.org

From: Fu Wei <fu.wei(a)linaro.org> This patch add a check_xsm_signature static function for detecting XSM from the second unknown module. If xen can't get the kind of module from compatible, we guess the kind of these first two unknown respectively: (1) The first unknown must be kernel; (2) The second unknown is ramdisk, only if we have ramdisk; (3) Start from the 2nd unknown, detect the XSM binary signature; (4) If we got XSM in the 2nd unknown, that means we don't load initrd.

[NOTICE] [PATCH 0/3] ARM's CpuDxe moving to new CpuExceptionHandlerLib

by Ard Biesheuvel

The CpuExceptionHandlerLib LibraryClass dependency is trivially satisfied on most ARM systems by the null implementation, i.e., an implementation that does absolutely nothing. The upstream implementation of ARM's CpuDxe will be refactored to delegate the registration and dispatch of exceptions to CpuExceptionHandlerLib, of which an ARM implementation (both AArch32 and AArch64) has been contributed by Eugene Cohen. This means all current users of ARM's CpuDxe will need to upgrade. Please refer to the attached patches #2 and #3 for an example. Ard Biesheuvel (3): Chips/TI/Omap35xx: drop CpuExceptionHandlerLib library class resolution Platforms/TI/BeagleBoard: move to ARM version of CpuExceptionHandlerLib Platforms/VExpress: move to ARM version of CpuExceptionHandlerLib Chips/TexasInstruments/Omap35xx/Omap35xxPkg.dsc | 1 - Platforms/ARM/VExpress/ArmVExpress.dsc.inc | 2 +- Platforms/TexasInstruments/BeagleBoard/BeagleBoardPkg.dsc | 2 +- 3 files changed, 2 insertions(+), 3 deletions(-) -- 2.5.0

[PATCH] Platforms/ARM: Juno: Acpi - DBG2 to aslc for UART1

by evan.lloyd＠arm.com

From: Sami Mujawar <sami.mujawar(a)arm.com> The DBG2 table is used to publish the presence of debug ports available on a system. The existing DBG2 table implementation configures the Juno UART0 port to be used for SPCR and DBG2. This prevents the usage of the Operating System Debugger when the EMS terminal is active. This patch: 1. Changes the usage of the UART ports as below: - Juno UART0 - for UEFI serial terminal and SPCR port. - Juno UART1 - for debug port. 2. It also replaces the Dbg2.asl file which described the DBG2 table in TDL format with Dbg2.aslc, which allows more flexibility by way of allowing the usage of PCDs. Dependency: * This patch requires ARM Trusted Firmware to configure the UART1 for Non-Secure World access.

Linux Tftpboot on ARM64

by Bhupesh Sharma

Hi Ryan, We are trying to boot Linux via tftp command on our NXP ARMv8 board. I found some relevant information about how this was tried and enabled on ARM Juno: 1. https://lists.linaro.org/pipermail/linaro-uefi/2015-January/000653.html 2. https://wiki.linaro.org/WorkingGroups/Kernel/ARMv8/TFTPJunoBoard We are able to use the tftp command on the Shell to get a kernel Image file from network and write it to a filesystem (for e.g. on a FAT32 formatted SD card). Now, I was wondering how we can use the same in conjunction with the LinuxLoader.efi application to tftp the 'kernel and rfs' images from network and pass the same to the LinuxLoader.efi, which can in-turn boot the kernel Image. Can you please let me know if my understanding is correct and point us to how this is achieved on ARM Juno. Thanks for the help. Regards, Bhupesh

[PATCH 0/2] OpenPlatformPkg: implement EFI_RNG_PROTOCOL for Juno

by Ard Biesheuvel

Since my KASLR implementation for arm64 Linux is based on the EFI_RNG_PROTOCOL (at least for UEFI systems), which is not yet widely available on systems that are under developement currently, this implements a pseudo-random version for ARM Juno. This code is not suitable for production, but since Juno is strictly a development platform, that concern does not apply here. Note that the library is delivered as a binary which prints a warning to the console the first time it is called.
