The PowerPC has both 32 and 64 bit CPUs within a single architecture
and collection of BSPs. This change set addresses cases where the
format specifier, type, or cast was not correct or portable across
32 and 64 bit environments.
This is an update of many lingering embedded brains GmbH licenses from
the RTEMS License to the 2-BSD license where possible depending on the
joint copyrights.
Updates #3053.
The VRSAVE feature of the Altivec unit can be used to reduce the amount of
Altivec registers which need to be saved/restored during interrupt processing
and context switches.
In order to use the VRSAVE optimization a corresponding multilib (-mvrsave) is
required, see GCC configuration. The -mvrsave option must be added to the
ABI_FLAGS of the BSP.
Currently only the -mcpu=e6500 based QorIQ BSP support this optimization.
Update #4712.
