本文详细介绍了RTK系统的初始化过程，包括HAL层初始化、DAL层初始化等关键步骤，并深入探讨了mac_probe、phy_probe等函数的功能及其实现原理。

最初接口
rtk_init:
hal_init
dal_mgmt_initDevice

hal初始化
hal_init:
/系统初始化，识别phy driver/
| hal_init_sys
| | osal_sem_mutex_create(Phy_sem,Miim_sem,Sds_sem,Tbl_sem)
| | phy_identify_init
| | | _phy_identify_phyctrl_register (supported_int_phys,supported_phys)
| | dal_mgmt_init
| dal_mgmt_mapper_clear
| hal_chipInfo_clear
/获取mac并初始化/
| mac_probe
| | hal_find_device
supported_devices rt_device_t
chip_id,rev_id,family_id,port_info,capacityInfo(各项表容量)，macPPInfo,macPPInfo
| | hwp_defaultProfilePort_build
| | hwp_parsedInfo_buildup
| | hal_find_driver
rt_major_driver_table rt_driver_s
type,driver_id,driver_rev_id,reg_list,table_list,portMask_list,macDrv,
reg_idx_max,regField_idx_max,table_idx_max,vendor_id
macDrv = rt_macdrv_t ,init,miim,table,port,mac_serdes,smi,miim_portSmi
| mac_init
| | fMdrv_init
/获取phy初始化/
| phy_probe
| phy_attach_hook_driver
