[PATCH 0/2] ArmPlatformPkg/ArmJunoPkg: boot and FDT cleanup

by Ryan Harkin

This small series removes a fair amount of broken code used to create default boot entries that don't work and install DT blobs depending upon that variant of the board this the code is running on, without supporting all the board variants now available. [PATCH 1/2] ArmPlatformPkg/ArmJunoPkg: don't create default boot entries [PATCH 2/2] ArmPlatformPkg/ArmJunoPkg: only have 1 PCD for the FDT

[PATCH] Platforms/ARM: Juno: set LAN9118 timeout PCD

by Ryan Harkin

The LAN9118 driver in EDK2 has been updated to include a PCD for over-riding the default auto-negotiation timeout. The default setting of 4000us is not long enough for Juno, so set it to 40000.

Compiling CPP files ARM64

by Daniel Samuelraj

We are able to compile CPP files for X64 using UDK2014 by using Visual Studio. How do we compile the same source for AARCH64? Appreciate the help! Thanks, Daniel

[PATCH 0/3] add ARM and AArch64 support

by Ard Biesheuvel

These patches have been in my personal queue for about two years, and have already been incorporated into the Ubuntu packaged version of sbsigntool. Patch #1 and #2 fixes some generic issues, and patch #3 introduces the ARM and AArch64 magic values in the PE/COFF header check, which is all that is needed to get sbsign to sign ARM images.

[PATCH v3 0/4] EmbeddedPkg/Lan9118Dxe: MemoryFence and PCD

by Ryan Harkin

This is a follow up from my previous patch [1] to add a PCD for the auto-negotiation timeout and the v2 series that followed it. Review comments on the edk2-devel mailing list and on the #linaro-enterprise IRC channel evolved the solution into two different patches: [PATCH 1/4] EmbeddedPkg/Lan9118Dxe: use MemoryFence [PATCH 2/4] EmbeddedPkg/Lan9118Dxe: add PCD for negotiation timeout Whilst I was editing the code, I also noticed a few non-functional quirks that were easy to fix: [PATCH 3/4] EmbeddedPkg/Lan9118Dxe: minor DEBUG tidyup [PATCH 4/4] EmbeddedPkg/Lan9118Dxe: rename TimeOut to Retries Changes since v2: - The number of stalls replaced in the first patch has been reduced. Any loop that is time bound now contains a MemoryFence and a Stall - The PCD was previously setting the Stall time for the auto-negotiation timeout. It now sets the total time to wait for auto-negotiation. - I dropped the Reviewed-by tags off patches 1 & 2 because the code has changed enough that I didn't think it was fair to keep them.

[edk2] [PATCH v4 0/3] support multiple PL061 gpio controllers

by Haojian Zhuang

Changelog: v4: * Use 64-bit value on PL061 register base address. * Use fallback to be compatible with current PcdPL061GpioBase value when platform gpio driver isn't present. * Remove the dependancy on PL061. Move the dependancy to platform gpio driver instead. v3: * Remove GPIO_PIN_MASK_HIGH_8BIT() and GPIO_PIN_MASK_LOW_8BIT(). * Avoid to use MmioAnd8() on updating GPIO DATA register, since PL061 could access each bit by specified register offset. * Add PLATFORM_GPIO_CONTROLLER structure in embedded gpio. * Support multiple PL061 gpio controllers in one platform. v2: * Append the patch to fix gpio pin mask macro.

Secure UEFI on ARM: Queries and Latest sbsigntool broken?

by Bhupesh Sharma

Hi, I am trying to do some hands-on on qemu for aarch64 to boot a secure kernel image and running into the following two issues. I would appreciate any pointers on the same. 1.

[PATCH v5 0/5] ArmPlatformPkg: remove unused code

by Ryan Harkin

This is another update to my original series titled: [PATCH 0/2] ArmPlatformPkg: Remove FVP and Juno Changes since v2: - Drop patch 6/6 'Revert "ArmPlatformPkg: Create an ARM Platform DSC / FDF / ArmPlatformLib template"' - Fix commit message for patch 1 - Rebase to the latest Tianocore tree ARM Ltd Platform support is migrating to use OpenPlatformPkg [1]. Currently, TC2, Juno and FVP exist both in EDK2's ArmPlatformPkg and in OpenPlatformPkg. And they are starting to diverge, with OpenPlatformPkg being the most up-to-date with current developments. To prevent this divergence, remove the .dsc and .fdf files from ArmPlatformPkg and leave OpenPlatformPkg as the master. 32-bit models are no longer tested or supported, so this series also removes the .dsc/fdf files for them. And the Sec library has no clients either, so that can also be removed as it hasn't been tested for a long time. We can't remove ArmJuno.dec yet because ACPI still uses it to set the include path to ArmPlatform.h. [PATCH v3 1/5] ArmPlatformPkg: remove ArmVExpress-CTA15-A7.dsc/fdf [PATCH v3 2/5] ArmPlatformPkg: remove ArmVExpress-FVP-AArch64.dsc/fdf [PATCH v3 3/5] ArmPlatformPkg: remove ArmJuno.dsc/fdf [PATCH v3 4/5] ArmPlatformPkg: remove ArmVExpress-RTSM-A15_MPCore.dsc/fdf [PATCH v3 v3 5/5] ArmPlatformPkg: remove unused Sec library This series can be found on the ARM Landing Team git tree [2].

[PATCH] EmbeddedPkg/Lan9118Dxe: add PCD for negotiation timeout

by Ryan Harkin

Add a PCD for the default link negotiation timeout so the platform can over-ride the default value. When the ARM Juno Development Platform uses the "EFI Network" option with then LAN9118 driver, it fails to boot the first time and so the board drops back to Shell again: Warning: LAN9118 Driver in stopped state Link timeout in auto-negotiation. Lan9118: Auto Negociation not supported. EhcExecTransfer: transfer failed with 2 EhcControlTransfer: error - Device Error, transfer - 2 Buffer: EFI Hard Drive Booting EFI Misc Device Booting EFI Misc Device 1 Booting EFI Hard Drive Booting EFI Network Warning: LAN9118 Driver not initialized Link timeout in auto-negotiation. Lan9118: Auto Negociation not supported. Booting EFI Internal Shell Exiting Shell drops the user back to the Intel BDS UI. Selecting "Continue" then succeeds in booting from the EFI Network: Booting EFI Misc Device Booting EFI Misc Device 1 Booting EFI Hard Drive Booting EFI Network ..MnpFreeTxBuf: Duplicated recycle report from SNP. MnpFreeTxBuf: Duplicated recycle report from SNP. [snip repeated errors] Discussion on the edk2-devel mailing list [1] prompted Laszo Ersek to suggest the time taken for the NIC to negotiate was causing a problem. He suggested the solution contained in this patch to provide a PCD configurable by the platform. Setting the PCD to 2000 seems to work for Juno R0, R1 and R2.
