[libcpu][am335x] Fix the booting failure when enabling MMU
...
Since the 16 domains are configured as the client domains in
mmu_setttbase(), a Permission fault is generated if the XN bit
(Execute-never) is set in the short-descriptor translation table
(for section and supersection). This leads to the booting failure
when enabling MMU for beagleboard bsp. Here is log:
----------------------------------------------------------------

short-descriptor translation table. The OS can be booted successfully
with applying this commit.

rm48x50: VFP lazy stacking
...
You need to turn on RT_VFP_LAZY_STACKING in rtconfig.h. By default, RTT
will turn on VFP for all threads and stack all the VFP registers. When
doing lazy stacking, VFP will only be turned on for the thread who
issued VFP instructions.
Currently, if a thread turned on VFP, it cannot be turned off. RTT will
never know what time the thread doesn't need VFP any more. The thread
might could turn off the VFP for it self in proper time.

We currently only support building with CCS and SCons is not using.
bsp/rm48x50/HALCoGen/HALCoGen.{hcg,dil} is the HALCoGen project file.
You may need to regenerate the source file as you like, providing that:
1, IRQ is in Dispatch Mode and the table entry is IRQ_Handler. The
channel 5 in enabled and connected to IRQ.
2, RTI driver is enabled and compare3 source is selected to counter1
and the compare3 will generate tick in the period of 10ms. This
value is coresponding with RT_TICK_PER_SECOND in rtconfig.h.
In CCS, you need to create a new CCS project and create link folders
pointing at bsp/rm48x50, libcpu/arm/rm48x50 and src/, include/. Remember
to add the include path to the Build Properties.
