【已评审】支持CPLD全资源自检功能

Hardware SIG Hardware评审
1

背景
现网出现多例CPLD芯片故障，表现为寄存器异常导致单板不开工、反复重启等，根因为厂家工艺问题，需要在装备阶段对CPLD进行全资源自检。

决策点
general_hardware增加私有类CpldSpaceTest以及相关属性声明，对应基础板和扩展板CSR中增加对象配置。

详细描述
（1）新增CpldSpaceTest类

属性名称 类型 属性说明
CpldIndex U8 CPLD索引值，表示第几片CPLD，从1开始计数
Manufacturer U8 CPLD厂商，表示当前对象配置的对应厂商，0：anlu，1：lattice，2：pango
TestFirmwares String[] CPLD检测固件列表，与hpm包中的case固件名称对应
RefreshFirmware String CPLD恢复固件名称，与hpm包中的refresh固件名称对应
CpldResultRegister U8 检测CPLD测试结果的寄存器
RefSmcChip U8[] 引用对应的Smc对象，在测试时阻止Smc访问使用
WaitTime U32 检测等待时间，单位: ms
RefLogicFirmware U8[] 引用CPLD升级对象，在UID组件匹配，确定升级使用的Chip，切换Jtag链路使用
RefBusIndex U8 获取测试结果对应Bus的参数，当前支持GPIO
RefMode String 获取测试结果的方式，当前支持GPIO和SMC

（2）新增CSR配置
基础板增加配置：

}

评审结论
（1）同意新增CpldSpaceTest类及相关属性用于CPLD全资源检测功能；
（2）CSR对象配置更适合放置在PSR中，但由于当前不支持跨文件引用对象及属性，且新增配置依赖LogicFirmware、Smc等对象，无法支持配置在PSR中，同意在基础板和扩展板CSR新增对象；

遗留问题
CSR需要打通跨文件引用功能，支持在PSR中引用其他文件对象
