[PATCH] Platforms/Styx: add missing GCD allocation of PCI resources

by Ard Biesheuvel

The resource apertures that the PCI root bridge uses to assign resources to subordinate devices need to be declared in the GCD memory map before allocations can be made from it. So add the missing code to do that. Also, declare the I/O port space as translated from its CPU visible memory offset, and take the translation into account into the I/O access routines.

Re: [Linaro-uefi] [PATCH v4] ArmPkg/AArch64Mmu: disable MMU during page table manipulations

by Heyi Guo

Hi Ard, I actually found this patch caused SERR on D02, for the library constructor it is using. The function AArch64LibConstructor will be called in every module if it directly or indirectly invokes ArmLib. Our case is like below: 1. We have a PEIM, which invokes HobLib -> PeiServicesLib -> PeiServicesTablePointerLib -> ArmLib. 2. So it will integrate this constructor and flush the code at the beginning of module entry. 3. For the code is running on Flash, we actually flush the flash area, and then a SERR occurs. I'm not sure if it is a common issue of generating SERR when flush flash space, but, as ArmLib is such a fundamental library, do we really need to make the function as a library constructor instead of being called on demand? Regards.

[PATCH] Platforms/AMD: remove bogus 4 GB limit in PciHostBridgeDxe

by Ard Biesheuvel

The copy-pasted PciHostBridgeDxe driver has some interesting restrictions that are difficult to fulfil on Seattle, i.e., its AllocateBuffer() and IoMap() operations require the DMA address to be below 4 GB. This would only makes sense in the presence of 32-bit only DMA bus masters that are not behind a SMMU, but in the Seattle case, it is completely pointless since it does not have any RAM below 4 GB in the first place. So simply drop these restrictions.

[PATCH v5] xen/arm64: check XSM Magic from the second unknown module.

by fu.wei＠linaro.org

From: Fu Wei <fu.wei(a)linaro.org> This patch adds a has_xsm_magic helper 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 unknowns respectively: (1) The first unknown must be kernel. (2) Detect the XSM Magic from the 2nd unknown: a. If it's XSM, set the kind as XSM, and that also means we won't load ramdisk; b. if it's not XSM, set the kind as ramdisk. So if user want to load ramdisk, it must be the 2nd unknown. We also detect the XSM Magic for the following unknowns, then set its kind according to the return value of has_xsm_magic. By this way, arm64 behavior can be compatible to x86 and can simplify multi-arch bootloader such as GRUB.

Re: [Linaro-uefi] [PATCH] Platforms/Juno: drop FACS table

Hi Ard. The FACS does expose the "GlobalLock" field. I'm not aware of anything that uses it right now, but it might conceivably break somebody's board driver.

[PATCH v2 00/23] Marvell Armada7040 SoC support

by Marcin Wojtas

Hello, Here is v2 version of the support. The patchset shrank a bit, because the custom RamDisk driver was replaced with the one already existing in a tree - yet because of lack of FAT formatting it's not functional for the platform purposes, but it's not crucial at this point. Also a custom UART driver has been replaced. Detailed list of changes is below. For convenience purpose whole patchset is available in the github: https://github.com/MarvellEmbeddedProcessors/edk2-open-platform/commits/opp… Any comments or remarks are mostly welcome. Best regards, Marcin Changelog: v1 -> v2 * Fix "may be used uninitialized" variables issue, branch compiles both with DEBUG and RELEASE flags * Remove I2C_FLAG_NORESTART dependency - replace it with local definition * Remove Marvell UART Library: - DW8250 IP has programming interface compatible with NS-16550. Since in edk2 there is support for 16550, internal library is unnecessary. - /Library/BaseSerialPortLib16550/BaseSerialPortLib16550.inf is used instead * RamDisk driver: - Remove old driver imported from EFI TOOLKIT 2.0 - Replace it with new MdeModulePkg/Universal/Disk/RamDiskDxe from edk2 - Lack of FAT formatting issue emerged * Add explicit dependency on IoLib in Drivers/Spi/SpiDxe.inf * Add poster's "Signed-off-by" registry to every commit message * Move to 05.04.2016 HEAD of edk2/master - Update CpuExceptionHandlerLib within OPP.
