...
* the initial support of synopsys designware ARC processor
using embARC_BSP, all synopsys ARC-based boards are
supported:
-ARC Software Development Platform
-ARC EM Starter Kit
-ARC EM Software Development Platform
-ARC HS Development Kit
-ARC IoT Development Kit
* The embARC BSP is a new generation embARC software development
package. It is designed to be the inter-layer between hardware and
operating system. BSP could hide the difference of hardware/boards,
provide a unified interface to upper-layer.
* the initial support of synopsys MWDT toolchain.
The DesignWare® ARC® MetaWare Development Toolkit builds upon
a 25-year legacy of industry-leading compiler and debugger products.
It is a complete solution that contains all the components needed to
support the development, debugging and tuning of embedded applications
for the DesignWare ARC processors.
* for detailed board information, pls go embarc.org.

MIPS common code was highly duplicated, This commit

The context and exception handle flow is mostly identical

we save FP registers in stackframe unconditionally.

[libcpu][C28x] Fix bugs of old c28x interrupt api which can not save and restore int status
...
In C28x DSP, interrupt status are stored in ST1 register. Both INTM and DBGM is used for masking interrupt, while the latter one is used in real-time debug mode. The origin function rudely enable and disable the interrupt without considering the recent interrupt status, which not only may cause problem in some situation but also is not in conformity with rt-thread design specifications. The new api will fix this bug.

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.

avoid to conflicting types for 'uint32_t' error.
...
already uint32_t is defined at components/libc/compilers/minilibc/stdint.h.
there is two ways to solve, using <stdint.h>/uint32_t pair or
<rtthread.h>/rt_uint32_t pair.
I choose former because this code belongs to C compiler, not RT-Thread system.

[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:
----------------------------------------------------------------

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.

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.
