It also maintains a checksum 7457d0f5c13SSimon Glass of the trace records (even if space is exhausted) so that the 7467d0f5c13SSimon Glass sequence of I/O accesses can be verified. 7477d0f5c13SSimon Glass 7487d0f5c13SSimon Glass When debugging drivers it is useful to see what I/O accesses were 7497d0f5c13SSimon Glass done and in what order. 7507d0f5c13SSimon Glass 7517d0f5c13SSimon Glass Even if the individual accesses are of little interest it can be 7527d0f5c13SSimon Glass useful to verify that the access pattern is consistent each time 7537d0f5c13SSimon Glass an operation is performed. In this case a checksum can be used to 7547d0f5c13SSimon Glass characterise the operation of a driver. The checksum can be compared 7557d0f5c13SSimon Glass across different runs of the operation to verify that the driver is 7567d0f5c13SSimon Glass working properly. 7577d0f5c13SSimon Glass 7587d0f5c13SSimon Glass In particular, when performing major refactoring of the driver, where 7597d0f5c13SSimon Glass the access pattern should not change, the checksum provides assurance 7607d0f5c13SSimon Glass that the refactoring work has not broken the driver. 7617d0f5c13SSimon Glass 7627d0f5c13SSimon Glass This works by sneaking into the io.h heder for an architecture and 7637d0f5c13SSimon Glass redirecting I/O accesses through iotrace's tracing mechanism. 7647d0f5c13SSimon Glass 7657d0f5c13SSimon Glass For now no commands are provided to examine the trace buffer. The 7667d0f5c13SSimon Glass format is fairly simple, so 'md' is a reasonable substitute. 7677d0f5c13SSimon Glass 7687d0f5c13SSimon Glass Note: The checksum feature is only useful for I/O regions where the 7697d0f5c13SSimon Glass contents do not change outside of software control. Where this is not 7707d0f5c13SSimon Glass suitable you can fall back to manually comparing the addresses. It 7717d0f5c13SSimon Glass might be useful to enhance tracing to only checksum the accesses and 7727d0f5c13SSimon Glass not the data read/written. 7737d0f5c13SSimon Glass 7740c19b4d1SSimon Glassconfig CMD_I2C 7750c19b4d1SSimon Glass bool "i2c" 7760c19b4d1SSimon Glass help 7770c19b4d1SSimon Glass I2C support. 7780c19b4d1SSimon Glass 77972a8cf8dSSimon Glassconfig CMD_LOADB 78072a8cf8dSSimon Glass bool "loadb" 78172a8cf8dSSimon Glass default y 78272a8cf8dSSimon Glass help 78372a8cf8dSSimon Glass Load a binary file over serial line. 78472a8cf8dSSimon Glass 78572a8cf8dSSimon Glassconfig CMD_LOADS 78672a8cf8dSSimon Glass bool "loads" 78772a8cf8dSSimon Glass default y 78872a8cf8dSSimon Glass help 78972a8cf8dSSimon Glass Load an S-Record file over serial line 79072a8cf8dSSimon Glass 79183a51ebaSAlex Deymoconfig CMD_LOAD_ANDROID 79283a51ebaSAlex Deymo bool "load_android" 79383a51ebaSAlex Deymo default n 79483a51ebaSAlex Deymo depends on ANDROID_BOOT_IMAGE 79583a51ebaSAlex Deymo help 79683a51ebaSAlex Deymo Load an Android Boot image from storage.
