Update #3850
|
|
|
|

This fixes an issue with the latest tool chain which adds the default
linker script in the endfile specification.

In "bsp/atsam: Simplify XDMAD_Handler()" (5f813694f68cee) the interrupt
callback has been made unconditional. That allowed to avoid some special
deadlock situations in error cases. But it removed part of the XDMAD
status handling.
This patch adds the ability to update the XDMAD status from the
callback if that is necessary for the driver.
Fixes #4173

The external UART over SPI device SC16IS752 uses the interrupt server
for interrupt processing. The interrupt server is also heavily used by
libbsd. The interrupt processing for the SC16IS752 is time critical and
doesn't work if network traffic is processed at the same priority.
With #4033 custom interrupt servers are available. Change
atsam_sc16is752_spi_create() to support user-defined interrupt servers.
Introduced atsam_sc16is752_spi_config to cut down the argument count of
this function.
Close #4039.

Use RTEMS_SYSINIT_ORDER_LAST_BUT_5 instead of RTEMS_SYSINIT_ORDER_LAST
to allow applications and support functions to place system
initialization handlers behind the standard handlers.

This allows to mix SC16IS752 chips with other interrupts.

For level triggered interrupts currently the handler would have been
called two times (assuming no one cleared the mask in a handler which
would have been bad because the handler couldn't process all other that
got cleared by accident). This patch allows the handler only to return
if nothing is left to do.

The watchdog timer (WDT) can be configure only once. Do not touch it in
the BSP since the application may want to use it.

Remove the channel status evaluation from XDMAD_Handler() and simply
hand over the status to the callbacks.

Add Doxygen groups for contributed code which would otherwise end up at

For proper 16 bits per word support we need probably some DMA
adjustments. For 9 to 15 bits per word we need support for the variable
peripheral select, see SR_MR[PS] register bit.

Load the channel interrupt mask only once.

The previous approach contained a severe bug which disabled the SPI
module in some cases leading to a blocked SPI bus.

Do not use SPID_Configure() since this will enable the peripheral each
time and performs a software reset.

Add and use <machine/rtems-bsd-kernel-space.h> and
<machine/rtems-bsd-user-space.h> similar to the libbsd to avoid command

This patch fixes an overflow in the frequency calculation of the SPI
driver for slow SPI speeds.

Quite a number of GMAC_... functions had a side effect of enabling the
transmit and receive. During the initialization of the ethernet driver,
that lead to the situation that the receive has been already enabled
while the DMA isn't set up correctly. Therefore the DMA interpreted the
values at address 0 as an DMA descriptor. When a packet is received
during that time, the behaviour is quite undefined.

This allows a user to overwrite some MPU settings. That can for example
be usefull for devices with special requirements that are connected to
the external bus interface.
