The number of memory map entries used exceeded the allocated count, thereby causing memory corruption. Fixed the number of Virtual Memory Map Descriptors allocated in describing the RTSM Memory Map. Also added an assert to confirm that the descriptor count has not been exceeded, in the hope that it may help highlight the problem should a new entry be added.

2016-10-24ArmPlatformPkg/PrePi: avoid global variable write to mSystemMemoryEndArd Biesheuvel
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>

2016-09-09ArmPlatformPkg/NorFlashDxe: use strictly aligned CopyMem()Ard Biesheuvel
The UEFI spec stipulates that unaligned accesses should be enabled on CPUs that support them, which means all of them, given that we no longer support pre-v7 ARM cores, and the AARCH64 bindings mandate support for unaligned accesses unconditionally. This means that one should not assume that CopyMem () is safe to call on regions that may be mapped using device attributes, which is the case for the NOR flash. Since we have no control over the mappings when running under the OS, and given that write accesses require device mappings, we should not call CopyMem () in the read path either, but use our own implementation that is guaranteed to take alignment into account.

Similarly, DC ZVA instructions are only supported on normal memory, not device memory. So remove the EFI_MEMORY_UC attribute that we set by default on system RAM.

2016-07-07ArmPlatformPkg: Set Juno debug serial port defaultsEvan Lloyd
Juno has several serial ports, one of which may be used for a remote debug interface (e.g. gdb, WinDbg). The debug serial port needs to be distinct from that used for UEFI trace to prevent corruption of debugger protocol messaging. The UEFI spec requires that serial devices be initialised to default settings. (11.8 Serial I/O Protocol - "The default attributes for all UART-style serial device interfaces are: 115,200 baud, ..." and 17.3.3 EFI Debugport Variable - "These defaults must be used in the absence of a DEBUGPORT variable...") This change adds initialization of the serial device reported in the ACPI DBG2 table. The initialisation is done early in the boot to allow the possibility of remote debug of UEFI itself. NOTE: This is functionally dependent on the DBG2 table being updated in OpenPlatformPkg, but is required as a precursor to that change.

2016-04-01ArmPlatformPkg: Add PCD for Pl011 UART InterruptSami Mujawar
This patch adds a PCD for the PL011 UART Interrupt as this is needed by the Serial Port Console Redirection Table.

2016-03-25ArmPlatformPkg: fixups for 64-bit pointersLeendert van Doorn
This retypes some stack base PCD as 64-bit, and fixes up a number of references to 64-bit PCDs (including the retypes ones), to use the correct PcdGet64() accessors. Note that, in the case of FixedPcdGet64, this does not actually caused any problems, since that resolves to an immediate value. But the generic PcdGetxx accessors should be typed according to the size of the PCD.

2016-03-14ArmPlatformPkg: PL061: support multiple controllerHaojian Zhuang
Support multiple PL061 controllers. If platform gpio driver couldn't be found, PL061 gpio driver will continue to load PcdPL061GpioBase as the register base. It could be compatible with the use case of current PL061 gpio driver.
