| | | | | | | | | | | | | | | This patch fixes the following Ecc reported error: File header doesn't exist File header comment missing the ""Copyright"" Even though a copyright is present in the header file, the leading '*' char prevents the Ecc tool from detecting it. According to the edk2 coding specifcation, section 5.2.3 "File Heading", there should not be leading '*' char.

* ArmPlatformPkg/PrePi: replace set/way cache ops with by-VA onesArd Biesheuvel2020-03-053-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Cache maintenance operations by set/way are only intended to be used in the context of on/offlining a core, while it has been taken out of the coherency domain. Any use intended to ensure that the contents of the cache have made it to main memory is unreliable, since cacheline migration and non-architected system caches may cause these contents to linger elsewhere, without being visible in main memory once the MMU and caches are disabled. In KVM on Linux, there are horrid hacks in place to ensure that such set/way operations are trapped, and replaced with a single by-VA clean/invalidate of the entire guest VA space once the MMU state changes, which can be costly, and is unnecessary if we manage the caches a bit more carefully, and perform maintenance by virtual address only. So let's get rid of the call to ArmInvalidateDataCache () in the PrePeiCore startup code, and instead, invalidate the UEFI memory region by virtual address, which is the only memory region we will be touching with the caches and MMU both disabled and enabled. (This will lead to data corruption if data written with the MMU off is shadowed by clean, stale cachelines that stick around when the MMU is enabled again.)

* ArmPlatformPkg/PrePi: avoid global variable write to mSystemMemoryEndArd Biesheuvel2016-10-244-44/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | The global variable mSystemMemoryEnd is initialized by PrePi only if it has not been initialized by ArmPlatformPeiBootAction(). This allows platforms executing under, e.g., ARM Trusted Firmware to dynamically reserve a window at the top of memory that will be used by the secure firmware. However, PrePi is a SEC module, and writing to a global variable violates the SEC constraints, since SEC and PEI may execute from NOR flash. So instead, initialize mSystemMemoryEnd statically. This will ensure it holds the correct value for all implementations where the value is not overridden, but still allows it to be overridden during the call to ArmPlatformPeiBootAction(). Note that this patch also fixes a latent bug on 32-bit platforms where a value of mSystemMemoryEnd exceeding 4 GB would be truncated to 32-bits rather than limited to (4 GB - 1) Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Acked-by: Laszlo Ersek <lersek@redhat.com> Tested-by: Ryan Harkin <ryan.harkin@linaro.org> Reviewed-by: Leif Lindholm <leif.lindholm@linaro.org>

| | | | | | | | | | | | | | | | | | When combining UEFI firmware built from Tianocore with ARM Trusted Firmware running in EL3, it is the responsibility of ATF that only a single core enters the UEFI firmware in EL2, and the remaining cores are released directly to the OS via PSCI SMC calls. In this case, we don't need the MpCore flavor of PrePi or PrePeiCore, but the UniCore flavor currently checks the CPU identification registers directly, and refuses to proceed if the boot CPU is part of a MpCore system.

It could cause stack corruption if the allocator allocates memory in this range.

| | | | | | | | | | | | | | | The commit on Fri Dec 6 2013: "ArmPlatformPkg/ArmPlatformStackLib: Do not directly use PcdArmPrimaryCore" has made the function ArmPlatformStackSet() overwrites the registers r6 and r7. These registers are used by PrePi to store the MPIDR and the the base of the system memory region used by UEFI.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The System Memory region might be out of the 32-bit memory space. This change has been validated on the FVP AArch64 model using 4GB of DRAM at 0x8_0000_0000: - # System Memory (2GB) - gArmTokenSpaceGuid.PcdSystemMemoryBase|0x80000000 - gArmTokenSpaceGuid.PcdSystemMemorySize|0x80000000 + # System Memory (4GB) + gArmTokenSpaceGuid.PcdSystemMemoryBase|0x800000000 + gArmTokenSpaceGuid.PcdSystemMemorySize|0x100000000 EFI Shell and Linux kernel boot successfully. Note: This change has not been validated on AArch32. I expect some early assembly code to not work.

There is a risk the mailboxes contain garbage at boot time. But it should be easy enough to clear the mailboxes when starting UEFI to workaround this limitation.
