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 2805d315bd rm48x50: fix bug in reg_test from FreeRTOS 
It does not satisfy AAPCS.

Grissiom 85ec844de9 rm48x50: add reg_test from FreeRTOS 
The code is GPLv2 so I think we could use it for free(both free beer and
free speech).

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.

Grissiom 60857630c0 simulator: fix serial_write 
printf("%s") will print a NULL terminated string, while rt_serial_write
should print buffer for size length. This also fix segfault when the
string is not null terminated but specified by size.

Grissiom b3e38f53b4 usbdevice/core: use static message queue 
Although currently the only message send to the queue is struct
udev_msg, in order to keep backward compacity and for extention in the
future, we set the size of message to 32.

Grissiom f0d50a7b36 usbdevice/core: use static thread instead of dynamic thread 
It also add two configurations for the USB device even loop thread:

    RT_USBD_THREAD_STACK_SZ to set the stack size, default to 2048
    RT_USBD_THREAD_PRIO     to set the priority, default to 8

You can overwrite the default values in rtconfig.h

Grissiom aa179e4438 cdc_vcom: not to start sending data when the data is already sending 
We start the sending transaction in SOF handler. But if the data is
already sending, start an other transaction will cause data lose.
Implement a state machine is cdc_vcom and avoid that.

Grissiom 778c4239b1 cdc_vcom: fix the bug that use ringbuffer pool as usb packet buffer 
This commit set the buffer for packet to CDC_MaxPacketSize which is a
reasonable value for it. However, maybe we should make
CDC_{RX,TX}_BUFSIZE configurable as well.
