书接上回，将WIFI名称和密码保存到存储当中。

使用easyflash保存WIFI名称和密码

创建存储相关代码

修改web/mlwip_https.c增加如下内容：

#include "storage.h"
#include "wifi_event.h"
#include "log.h"

....


   // 将 wifi 信息写入 存储
   flash_erase_set(SSID_KEY, ssidValue);
   flash_erase_set(PASS_KEY, pwdValue);

   // 开启 sta 模式，连接WIFI
   // 重启设备
   LOG_W("system 2s reset ");
   vTaskDelay(2000/portTICK_PERIOD_MS);
   GLB_SW_System_Reset();

修改proj.conf增加如下内容：

# easy flash
set(CONFIG_PARTITION 1)
set(CONFIG_BFLB_MTD 1)
set(CONFIG_EASYFLASH4 1)

修改CMakeLists.txt增加如下内容：

...

sdk_add_include_directories(storage)

...

target_sources(app PRIVATE
    storage/storage.c
    web/cJSON.c
    web/mlwip_https.c
)

对 flash_prog_cfg.ini 配置文件进行了一些注释
