project:build.sh: Added fastboot support; custom modifications to U-Boot and kernel implemented using patches.

project:cfg:BoardConfig_IPC: Added fastboot BoardConfig file and firmware post-scripts, distinguishing between
the BoardConfigs for Luckfox Pico Pro and Luckfox Pico Max. project:app: Added fastboot_client and rk_smart_door
for quick boot applications; updated rkipc app to adapt to the latest media library. media:samples: Added more
usage examples. media:rockit: Fixed bugs; removed support for retrieving data frames from VPSS. media:isp:
Updated rkaiq library and related tools to support connection to RKISP_Tuner. sysdrv:Makefile: Added support for
compiling drv_ko on Luckfox Pico Ultra W using Ubuntu; added support for custom root filesystem.
sysdrv:tools:board: Updated Buildroot optional mirror sources, updated some software versions, and stored device
tree files and configuration files that undergo multiple modifications for U-Boot and kernel separately.
sysdrv:source:mcu: Used RISC-V MCU SDK with RT-Thread system, mainly for initializing camera AE during quick
boot. sysdrv:source:uboot: Added support for fastboot; added high baud rate DDR bin for serial firmware upgrades.
sysdrv:source:kernel: Upgraded to version 5.10.160; increased NPU frequency for RV1106G3; added support for
fastboot.

+# RT-Thread RTC 设备
+
+## 1、介绍
+
+RT-Thread 的 RTC （实时时钟）设备为操作系统的时间系统提供了基础服务。面对越来越多的 IoT 场景，RTC 已经成为产品的标配，甚至在诸如 SSL 的安全传输过程中，RTC 已经成为不可或缺的部分。
+
+## 2、使用
+
+应用层对于 RTC 设备一般不存在直接调用的 API ，如果使用到 C 标准库中的时间 API （目前主要是获取当前时间的  `time_t time(time_t *t)`），则会间接通过设备的 control 接口完成交互。
+
+> 注意：目前系统内只允许存在一个 RTC 设备，且名称为 `"rtc"` 。
+
+### 2.1  设置日期
+
+```C
+rt_err_t set_date(rt_uint32_t year, rt_uint32_t month, rt_uint32_t day)
+```
+
+|参数                                    |描述|
+|:-----                                  |:----|
+|year                                    |待设置生效的年份|
+|month                                   |待设置生效的月份|
+|day                                     |待设置生效的日|
+
+### 2.2 设置时间
+
+```C
+rt_err_t set_time(rt_uint32_t hour, rt_uint32_t minute, rt_uint32_t second)
+```
+
+|参数                                    |描述|
+|:-----                                  |:----|
+|hour                                    |待设置生效的时|
+|minute                                  |待设置生效的分|
+|second                                  |待设置生效的秒|
+
+### 2.3 使用 Finsh/MSH 命令 查看/设置 日期和时间
+
+#### 2.3.1 查看日期和时间
+
+输入 `date` 即可，大致效果如下：
+
+```
+msh />date
+Fri Feb 16 01:11:56 2018
+msh />
+```
+
+#### 2.3.2 设置日期和时间
+
+同样使用 `date` 命令，在命令后面再依次输入 `年` `月` `日` `时` `分` `秒` （中间空格隔开, 24H 制），大致效果如下：
+
+```
+msh />date 2018 02 16 01 15 30    # 设置当前时间为 2018-02-16 01:15:30
+msh />
+```
+
+### 2.4 启用 NTP 时间自动同步
+
+如果 RT-Thread 已接入互联网，可启用 NTP 时间自动同步功能，定期同步本地时间。
+
+在 menuconfig 中启用 `RTC_SYNC_USING_NTP` 配置。启用该功能后，会自动开启 [netutils package](https://github.com/RT-Thread-packages/netutils) 的 NTP 功能。同时务必确保 RT-Thread 网络访问正常。
+
+启用该配置后，还有两个配置是用户可选配置：
+
+- `RTC_NTP_FIRST_SYNC_DELAY`: 首次执行 NTP 时间同步的延时。延时的目的在于，给网络连接预留一定的时间，尽量提高第一次执行 NTP 时间同步时的成功率。默认时间为 30S；
+- `RTC_NTP_SYNC_PERIOD`: NTP 自动同步周期，单位为秒，默认一小时（即 3600S）同步一次。
+
+> 注意：如果没有使用组件自动初始化功能，则需手动调用 `int rt_rtc_ntp_sync_init(void)` ，完成该功能初始化。
+
+### 2.5 启用 Soft RTC （软件模拟 RTC）
+
+这个模式非常适用于对时间精度要求不高，没有硬件 RTC 的产品。
+
+#### 2.5.1 使用方法
+
+在 menuconfig 中启用 `RT_USING_SOFT_RTC` 配置。
+
+> 注意：如果没有使用组件自动初始化功能，则需手动调用 `int rt_soft_rtc_init(void)` ，完成该功能初始化。
