5d8d55a1cd dev/serial: Simplify zynq_uart_reset_tx_flush()
Load the status register only once.  Use _IO_Relax() to reduce bus
traffic while waiting and simplify testing.

6757607199 dev/serial: Do not output '\r' during reset
It is not clear why this is necessary.  For example, the
zynq_uart_initialize() does not issue the '\r' before waiting for an
inactive transmission state.

a078b091c1 dev/serial: Use _IO_Relax()
This reduces the system bus load while waiting for a state change.  In
addition, it simplifies testing by using a wrapped _IO_Relax().

7be49773c0 bsps/shared/zynq-uart-polled: fix bug in zynq_uart_initialize()
Similar to the recent commit in tms570-sci.c, the assumption that a UART will
only see printable ASCII characters, instead of any value in the range
0x00-0xFF, is wrong.

A non forgiving binary protocol will be thrown off by this driver sending
"\r\r\r\r" when initializing.

If a user wants to flush the interface, they should explicitely use the
dedicated function `tcflush(fd, TCIOFLUSH);`.

333a1aee2b posix/aio_misc-c/rtems_aio_completed_list_op(): Path with no lock release.
Coverity CID 1619144

In rtems_aio_completed_list_op() memory was getting freed without releasing
a lock.

This commit should also solve coverity issues 1619145, 1619143 and 1619142
since they all seem to be generated by rtems_aio_completed_list_op().

Closes #5127

29a0d99bfd cpukit/libmisc/shell:fix command df overflow
- change type unsigned to uint64_t, it might overflowed if
    the size is greater the 4GB.
  - increase buffer size is to eliminate the compiler's warning
    that the buffer might be too small

ce1fb41a6c kvprintf(): Fix '+' conversion handling
For example, printf("%+i", 1) prints "+1".  However, kvprintf() did
print just "1" for this example.  According to PRINTF(3):

  A sign must always be placed before a number produced by a signed
  conversion.

For "%+r" radix conversions, keep the "+" handling as it is, since this
is a non-standard conversion.  For "%+p" pointer conversions, continue
to ignore the sign modifier to be in line with libc.

This change allows to support the ' conversion modifier in the future.

The struct timespec tv_sec member is of type time_t.  Make sure that all
variables related to this member are of the type time_t.  This is important for

9d6f171039 bsps/i386/include/bsp/irq.h is pc386 specific
The IRQ list in this file are specific to PC hardware and should be
part of the BSP. Further, there are paravirtualized environments which
do not follow the PC hardware IRQ list. Moving this avoids collisions.

d670dafaa4 posix/lio_listio.c: corrected return when RTEMS_POSIX_API is undefined
Modified the body of lio_listio(), to make sure it return -1 and sets
errno to ENOSYS, when RTEMS_POSIX_API is not defined.

The psxenosys test has been modified to test for lio_listio() only
when RTEMS_POSIX_API is not defined. In the test all the puts() have
been removed. If kept they would have made the output of the test depending
on the build configuration, making the content of psxenosys.scn inconsistent.
Removing the puts() makes the .scn file valid regardless of the build
configuration.

Additionally, rtems_aio_notify() in aio_misc.c has been modified,
simplifying it and reducing the part inside the ifdef.

Closes #5125

6dee307542 bsps/stm32h7: Add SPI support
This adds support for the 6 SPI interfaces on the STM32H7 series chips
with an initial example for the stm32h750b discovery kit development
board. Configuration is similar to existing peripherals. Chip select
lines are software-controlled since the SPI peripheral only supports a
single hardware-controlled chip select line. This implementation does
not use interrupts.

f61086a404 Revert "bsps/stm32h7: Workaround STM32 H7 errata by enforcing aligned access only"
This reverts commit d81bf04501.

The commit is reverted as this is only partial solution and remaining part
to fix properly is extremely hard and usually done in completely diffetrent
way. Hence let's not enforce compiler but rather enforce RTEMS/H7 users.

1b6684ee2b cpukit/posix/aio*: Added support for lio_listio()
This commit adds support for lio_listio().
psxaio05 has been added to test the new method.
To avoid code duplication, the body of aio_read and aio_write has been
moved in two helper methods. In this way i can use it also in lio_listio().

In addition to that, a limit on the number of total aio operation enqueued
has been added.

3b053f6919 bsps/shared: Add Abracom EOZ9 RTC driver
The EOZ9 RTC has a similar register interface like the MCP7940M (and
quite some other I2C RTCs). This commit:

* Extracts the generic parts from MCP7940M and moves it into a generic
  i2c-rtc driver.
* Uses the new i2c-rtc for the MCP7940M.
* Uses the new i2c-rtc for the new Abracom EOZ9.
