Add support to configure the second region of DDR memory if the
BSP configured RAM size is greater than 2G.
Add the second region's memory to the heap.
This follows current conventions.
Two have been left behind for now until we decide what to do as they are
imports.
* cpukit/compression/xz/COPYING
* cpukit/libmisc/uuid/COPYING
Add filename length checks to prevent the creation of files and folders
that cannot be listed, unlinked or renamed by subsequent calls.
These changes are sufficient to make the jffs2fsrenamelongname and
jffs2nandfsrenamelongname testcases pass.
Updates #5073
Currently, if a BSP is built without MPU alignment enforcement, the MPU
is still enabled and can produce a non-functional binary since code can
be mixed with data within a memory region and memory regions are marked
as read-only or no-execute based on section addresses and sizes leading
to overlapping regions being defined which causes the later-defined
region to take precedence. This change disables the MPU when alignment
is not enforced, allowing the binary to function.
In _Terminate(), everything after invoking the fatal extensions is essentially
dead code. Simplify this code block and provide a reasonable safe fall-back
for badly configured applications. Just disable masked interrupts and execute
an idle loop.
Update #5067.
Previously the first cluster of the file was not updated when
truncating to 0 but was in any case freed.
Now the first cluster of the file is updated during the truncation,
leaving the directory entry in a consistent state.
Closes#2757
This is intended to close any valid FDs that were opened, but 0 is also
a valid FD. This change ensures that a FD of 0 is also closed properly.

off_by_one: Testing whether handle fd is strictly greater than zero is
suspicious. fd leaks when it is zero.
The patch changes compiler ABI flags option and adds -mno-unaligned-access
there. Usage of this option is also officially recommended way
by the errata document how to work around the issue. For more details
about the errata please see referenced issue number.
Closes#5110.
Fix a race condition in which a file opened with O_TRUNC is made
available to other file functions expecting a file descriptor before
the truncation is performed.
This is only possible if the other thread was using an invalid file
descriptor as the open call has yet to finish.
Closes#5109
- Move the APIC implementation to its on file instead of having it in clock.c;
- Use the MADT for retrieving the Local APIC base address;
- Initialize the APIC during interrupt initialization.
Add a method for initializing the ACPICA table subsystem earlier than
the initilization of the entire ACPICA subsystem. Also add a method to
walk through the subtables of an ACPI table
Coverity Scan spotted the possibility that the
_Objects_Information_table could be over-indexed if the API
value provided was too high. This function is only used during
initialization and the input should be trusted. Adding a debug
_Assert() emphasizes this trust.

Closes#5084.
There is certainly no USB 20 TG while there is a known USB 2 OTG tech. The
crash caused by this is well observed from media01.exe from libbsd compiled
for H7 and run on the board.

O_SYNC and O_DSYNC have the same value which led Coverity to note that
checking for both values in if's or switches leads to dead code. The
solution is to add a cpp check that they are equal and enough commentary
so if they ever are not the same, there is a hint as to why the cpp
check got tripped.
Closes#5100.
This fixes the ECC info struct naming such that they all use the _Info
suffix. This also adds comments describing which structures are paired
with which event types.
- Implements necessary ACPICA OS Services Layer interfaces;
- Retrieve the RSDP from the FreeBSD Bootloader for amd64 or from multiboot2 for amd64efi;
- Add ACPI initialization routine;
- Use ACPI in bsp_reset.
