将Doxygen输入文件(由Doxyfile中的INPUT定义)中的失效Doxygen分组指令(如/*@*/和/*@}*/)更改为有效的分组指令(如/**@*/和/**@}*/);(此处只对INPUT中的文件做了修改,bsp目录下和libcpu目录下存在近万个失效的Doxygen分组指令,但由于不作为文档的输入文件且这些文件过于庞大老旧,没有对这些文件中的无效指令做修改)
将图片文件统一放入了images目录下;
修改了Doxyfile和部分Doxygen注释,使得Doxyfile能够定位到新的代码路径且不受重复实现的影响;
解决了一些注释中的参数名不匹配、参数多余/缺失等问题。

[GD32]add gd32470z-lckfb (#7022)
* --复制gd32450z-eval 作为立创梁山派 gd32470z-lckfb的模板进行移植
* -修改模板keil工程的配置,IROM需要注意总共为1024k,分为Code  area 和Data area  ,IRAM1为 : 512K-64K=448K=458752=0x70000。
-重新用ENV生成编译固件
片上SRAM可分为4块,分别为SRAM0(112KB)、SRAM1(16KB)、SRAM2(64KB)和TCMSRAM(64KB)。SRAM0、SRAM1和SRAM2可以被所有的AHB主机访问,然而,TCMSRAM(紧耦合存储器SRAM)只可被Cortex ® -M4内核的数据总线访问。BKPSRAM(备份SRAM)应用于备份域,即使当VDD供电电源掉电时,该SRAM仍可保持其内容。附加SRAM(ADDSRAM)只在一些特殊的GD32F4xx器件中可用。由于采用AHB互联矩阵,上述SRAM块可以同时被不同的AHB主机访问,例如,即使CPU正在访问SRAM0,USBHS也可以访问SRAM1。

* -修改IAR编译的链接脚本
* --修改Flash和RAM大小
-RAM大小为448k是因为512K-64K=448K,其中后面的64K为TCMSRAM(紧耦合存储器SRAM)只可被Cortex ® -M4内核的数据总线访问,先不要乱分配
* -修改MDK链接脚本
* -修改board.h
* -修改MCU型号
* -Finsh控制台和LED1闪灯程序工作正常,串口控制台名称错误,从uart改为uart0
-Scons正常生成工程
* -发现GD32固件库当前没有240Mhz的时钟配置,将固件库升级为GD32F4xx_Firmware_Library_V3.0.3-发布时间为2023-01-04
* -修改bsp/gd32/arm/gd32407v-start/board/SConscript文件
* -修改led1和change logs
* -按照提交规范使能 One ELF Section per Function(MDK) 并用scons重新生成工程
* -发现整个GD32的IAR模板工程template.eww 是没有的,所以当前是不支持IAR开发的,需要后面学习一下IAR使用再实现了。
* -使用formatting源码格式化工具跑一边gd32470z-lckfb目录
* -使用formatting源码格式化工具跑一遍[components/net/netdev/src/netdev.c]
-三个月前的提交多了几个空格

[spi]添加rt_spi_bus_attach_device_cspin 函数 (#6916)
这个函数实现了原先的挂载功能,并且调用pin框架,初始化cs引脚,是一个功能相对完善的挂载函数。用户也能更简单的使用。
该函数取代rt_spi_bus_attach_device,后续rt_spi_bus_attach_device会被逐渐淘汰掉。新的BSP以及软件包应当使用rt_spi_bus_attach_device_cspin新函数。

STM32L475潘多拉测试通过。

这是微软关于此问题的链接:
 https://learn.microsoft.com/zh-cn/windows-hardware/drivers/usbcon/usb-driver-installation-based-on-compatible-ids#usbsersys-installation
Windows 10 及更高版本
从 Windows 10 开始,Usbser.inf 已添加到 %Systemroot%\INF 目录,该目录加载 Usbser.sys 作为设备堆栈中功能设备对象 (FDO) 。 如果设备属于通信和 CDC 控制设备类, Usbser.sys 加载。 无需编写自己的 INF 来引用驱动程序。 驱动程序是基于与包含在 Windows 中的其他 USB 设备类驱动程序相似的兼容 ID 匹配来加载的。

USB\Class_02

USB\Class_02&SubClass_02

如果要自动 加载Usbser.sys, 在设备描述符中将类代码设置为 02,将子类代码 设置为 02。 有关详细信息,请参阅 USB 通信设备类。 使用此方法时,无需为设备分发 INF 文件,因为系统使用的是 Usbser.inf。
如果设备指定类代码 02,但子类代码值不是 02,则 Usbser.sys不会自动加载 。 即插即用管理器尝试查找驱动程序。 如果找不到合适的驱动程序,则设备可能未加载驱动程序。 在这种情况下,你可能需要加载自己的驱动程序或编写引用另一个内置驱动程序的 INF。

[CAN]update struct can_filter_item and rt_can_msg (#6556)
* 修改ry命令,已便于自定义保存路径

* modified:   components/utilities/ymodem/ry_sy.c

* 修复从被动错误恢复后发送返回异常

* 修复在自动重传模式下,ACK异常阻塞线程
- 删除TX中断函数else分支。仅当RQCP位 置一才进入该中断
- 添加SCE中断函数中关于ACK_ERR的else判断。自动重传模式下会进入该判断,打断自动重传释放完成量。

* 增加对于CAN1与CAN2的SCE中断和TX中断的公共处理函数

* formatting格式化代码

* update struct can_filter_item and rt_can_msg
1. 对过滤器号和索引号结构体定义中同一名称hdr进行重命名hdr_bank和hdr_index,
以便准确区分.采用宏定义兼容以前变量名.
2. 添加接收标识rxfifo,已指明是哪个RXFIFO.

* 更正42M下的波特率

* 修复接收获取索引号错误

* 添加接收标识

* 更新注释

* 取消CANFD限制

* update struct can_filter_item and rt_can_msg

a1012112796 5370d4da50 replace `rt_enter_critical` with `dfs_lock` for list_fd
I found that if use mutex in `rt_kprintf`,
the `rt_enter_critical` will create a assert
error later. after chehcking,I found all
operation with fd_table has using
`dfs_lock/unlock` to protect. so I think
using `dfs_lock` is enough. thanks.

lseek()函数中,当seek到文件的位置和当前位置相同时,不需要调用dfs_file_lseek()函数,直接返回当前位置即可。 (#6498)
当seek到文件的位置和当前位置相同时,不需要调用dfs_file_lseek()函数,直接返回当前位置即可。
同时,以lseek(fd,0,SEEK_CUR)的方式执行函数可以返回文件当前读去位置,可以实现
ftell()的功能.
以lseek(fd,0,SEEK_CUR)的方式执行函数返回文件当前位置,实现ftell()的功能时不用调用dfs_file_lseek()函数,提高效率;seek(fd,0,SEEK_CUR)本来就能返回当前位置。
