- These calls clash with the Linux IO header in LibBSD. Making these
conditional here means BSPs build and the imported Linux header is
untouched.
Updates #4245
- Add support to the BSP to enable irq-generic management
- Update the powerpc shared irq code to support irq-generic. This
is an opt in option for existing powerpc bsps. This change
should be simpler now
- Fix a number of issues in ISA IRQ controller handling by porting
fixes from the i386 (PC) BSP
Closes#4238Closes#4239
- The call to enable the openpic irq for the ISA bridge fails
because the IRQ used is offset by the ISA bus signals and
the openpic call expects an IRQ relative to its signals.
- Add the MVME 2600/2700 to the list of boards with an ISA bridge.
Closes#4231
Use the idle stack to buffer early uses of printk(). Print the buffered
characters during initialization when the UART is available and before
the idle stack is used normally.
This fix relates to a Coverity issue (PW.SET_BUT_NOT_USED).
There is not need to check that vector >= BSP_INTERRUPT_VECTOR_MIN since
BSP_INTERRUPT_VECTOR_MIN is zero and vector is unsigned.
This fix relates to CID 1399742 (NO_EFFECT).
If CPU_DATA_CACHE_ALIGNMENT == CPU_INSTRUCTION_CACHE_ALIGNMENT we had
dead code with the previous implementation.
This fix relates to CID 1399776 (DEADCODE).
For i.MX7 U-Boot initializes the system counter. On i.MX6 Barebox is
often used which doesn't initialize the counter. With this patch, we try
to auto-detect whether the counter is initialized or not and do the
initialization ourself if necessary.
Closes#3869
This allows an application to get the registers of the LPSPI. That is
usefull for applications that want to use DMA for a very specialized and
highly optimized communication.
Update #4180
Note: The changes have been done with portability in mind. The driver
should (in theory) be able to replace the original one in the MPC BSPs
too. For full compatibility an adaption layer and especially a test
would be necessary. Because both are missing, don't integrate it into
the MPC BSP now.
Update #4180
RTEMS OFW is a FDT only implementation of the OpenFirmWare
interface. This API is created to be compatible with FreeBSD
OpenFirmWare interface. The main intention is to make
porting of FreeBSD drivers to RTEMS easier.
Most functions implemented have an direct one-one mapping
with the original OFW API and some extra auxiliary functions
were implemented to make working with device trees easier in
RTEMS.
Update #3784
This BSP supports the Arm Fixed Virtual Platform. Only the Cortex-R52
processor configuration is supported by the BSP. It should be easy to
add support for other variants if needed.
Update #4202.
Set the VBAR to the vector table in the start section before
bsp_start_hook_0() is called to earlier handle exceptions in RTEMS.
Set the VBAR to the normal vector table in start.S for the main
processor. Secondary processors set it in bsp_start_hook_0().
Update #4202.
