qz721 61f2a71511 Rename 'platform.h' in 'imx6ul' and 'qemu-vexpress-a9' BSPs.
This filename conflicts with the 'mbedtls' package. They are renamed
in the name of the corresponding chips and included in 'board.h'.
Files that rely on this file should include 'board.h' instead.

Adrian Huang 4222677933 [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:

----------------------------------------------------------------
SD/MMC found on device 0

117 bytes read in 3 ms (38.1 KiB/s)

\## Starting application at 0x80200000 ...

----------------------------------------------------------------

This commit removes the XN bit configuration in the section of the
short-descriptor translation table. The OS can be booted successfully
with applying this commit.

Grissiom 24fc6e6ebb 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.

VFP instructions only have IA(Increment After)/DB(Decrement Before)
mode. To keep consistency, just change STM/LDM to DB/IA accordingly.

Grissiom f08df08897 rm48x50: optimize a BEQ
Use condition flag in the ORR. This could eliminate a BEQ.

Grissiom 19fe6251e7 rm48x50: optimize context_switch_interrupt_to by reuse registers
When saving thread registers in context_switch_interrupt_to, we don't
change them, just move them. So there is no need to always r0-r3 from
stack to the real r0-r3. So just use the intermediate registers and
eliminate 2 MOV.

Grissiom 3d0647efb3 rm48x50: optimize context_switch_interrupt_do
Substitude STMFD, MOV, ADD with STMFD, SUB. It reduce one instruction.
Tested on board and it works like a charm.

Grissiom b39d038cf0 rm48x50: utilize CPS instruction and remove some useless code 2013-05-26 16:55:39 +08:00
Grissiom f51bce3fed add rm48x50 bsp and libcpu
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.
