The current ZynqMP BSPs don't have _qemu in their name as do all other
RTEMS BSPs that are specifically made to run on QEMU. This fixes the
naming for those ZynqMP BSP variants for easier identification.
AArch64 on hardware is often started at EL2 instead of EL1 from either
u-boot or a first stage bootloader. This allows RTEMS to drop from EL2
execution to EL1 to operate as normal.
Remove usage of SUBALIGN() in aarch64 linkcmds which works around a
difference in behavior on AArch64 platforms. This is no longer necessary
since alignment is now enforced explicitly.
Closes#4178.
- 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

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.
This adds some commands that are usefull for debugging simple serial
interfaces.
Even if they are a complete re-implementation, the i2c* commands use a
simmilar call like the Linux i2c tools.
