zhushengle 64e49aba7c feat: 支持L1 低功耗框架 
方案描述：
   和L0保持一致，上层通过proc文件系统操作：
   power_mode  支持的低功耗模式，通过对该文件进行write操作可以设置低功耗模式
   power_count powermanager模块通过对该文件操作，和内核进行交互，简要流程如下：
     while (1) {
       open  // 打开该文件
       read  // 使powermanager低功耗任务常阻塞，当系统无任何模块持锁时，会唤醒该任务
       write // 进行低功耗流程
       close // 关闭该文件
     }
   power_lock    write该文件，持锁
   power_unlock  writw该文件，释放锁

LiteOS2021 e748fdbe57 feat: L0~L1 支持Lms 
1.【需求描述】：
   支持内核态和用户态堆内存非法访问检测，包括：越界访问、double free、释放后使用；支持libc常用高频函数内存检测；支持安全函数内存检测；读写检测可配可裁剪。
2.【方案描述】：
   L0 ~ L1:
   (1).影子内存映射与标记
   (2).编译器使能-fsanitize=kernel-address 自动插桩检测点
   (3).实时校验影子内存的合法性；
   (4).错误访问打印回溯栈

BREAKING CHANGE: 新增支持API:

LOS_LmsCheckPoolAdd使能检测指定内存池
LOS_LmsCheckPoolDel不检测指定内存池
LOS_LmsAddrProtect为指定内存段上锁，不允许访问
LOS_LmsAddrDisableProtect去能指定内存段的访问保护

LiteOS2021 6e0a3f10bb feat: L0-L1 支持Perf 
1.【需求描述】：
         L0-L1 支持Perf，提供2种模式的配置， 及3大类型的事件配置：
         2种模式：计数模式（仅统计事件发生次数）、采样模式（收集上下文如任务ID、pc、backtrace等）。
         3种事件类型：CPU硬件事件（cycle、branch、icache、dcache等）、OS软件事件（task switch、mux pend、irq等）、高精度周期事件（cpu          clock）。
    2.【方案描述】：
         L0:
         基于事件采样原理，以性能事件为基础，当事件发生时，相应的事件计数器溢出发生中断，在中断处理函数中记录事件信息，包括当前的pc、当前运         行的任务ID以及调用栈等信息。
         L1:
         新增perf字符设备，位于“dev/perf”，通过对设备节点的read\ioctl,实现用户态perf

    BREAKING CHANGE:
    1.新增一系列perf的对外API，位于los_perf.h中.
    LOS_PerfInit配置采样数据缓冲区
    LOS_PerfStart开启Perf采样
    LOS_PerfStop停止Perf采样
    LOS_PerfConfig配置Perf采样事件
    LOS_PerfDataRead读取采样数据
    LOS_PerfNotifyHookReg 注册采样数据缓冲区的钩子函数
    LOS_PerfFlushHookReg 注册缓冲区刷cache的钩子

    2. 用户态新增perf命令
  【Usage】:
./perf [start] /[start id] Start perf.
./perf [stop] Stop perf.
./perf [read nBytes] Read nBytes raw data from perf buffer and print out.
./perf [list] List events to be used in -e.
./perf [stat] or [record] <option> <command>
         -e, event selector. use './perf list' to list available events.
         -p, event period.
         -o, perf data output filename.
         -t, taskId filter(whiltelist), if not set perf will sample all tasks.
         -s, type of data to sample defined in PerfSampleType los_perf.h.
         -P, processId filter(whiltelist), if not set perf will sample all processes.
         -d, whether to prescaler (once every 64 counts), which only take effect on cpu cycle hardware event.

3. 原platform下不属于平台的公共代码抽到kernel/common下，只留板级链接脚本和一些编译脚本指向device目录下触发平台相关的编译
4. 对外公共头文件统一抽到对外include路径
5. 废弃宏，头文件清理

1.【需求描述】
            L0~L1 支持Trace，提供两种工作模式：在线模式、离线缓存模式， 用于按时间线追踪系统事件，如任务切换、中断、ipc等。
        2.【方案描述】
            L0:

            (2).触发桩后，收集系统上下文信息
            (3).离线模式则写入内存，用户可通过dump导出；
            (4).在线模式通过pipeline对接IDE进行可视化解析和展示；
            L1:

2、增加默认的系统模块适配层，处理通用内核态和用户态故障日志抓取和保存。
3、BBOX特性默认关闭，若想使用此特性，请在内核配置文件中增加如下编译选项：
LOSCFG_BLACKBOX=y
LOSCFG_SAVE_EXCINFO=y
LOSCFG_SAVE_EXCINFO可以帮助抓取更多的故障日志。
4、若已经打开BBOX特性，想快速验证此特性，请添加如下编译选项：

Linux RomFS and you can create such a file system using the tool genromfs.
2, there are two major changes against with the original Nuttx romfs:
    1), it is memory-based: all contents of the fs are stored in the
        memory in the very first stage of "mount".
    2), this version of romfs is altered to be compatible with our new
        version of VFS to take advantage of vnode cache and path cache.
