It also maintains a checksum 700 of the trace records (even if space is exhausted) so that the 701 sequence of I/O accesses can be verified. 702 703 When debugging drivers it is useful to see what I/O accesses were 704 done and in what order. 705 706 Even if the individual accesses are of little interest it can be 707 useful to verify that the access pattern is consistent each time 708 an operation is performed. In this case a checksum can be used to 709 characterise the operation of a driver. The checksum can be compared 710 across different runs of the operation to verify that the driver is 711 working properly. 712 713 In particular, when performing major refactoring of the driver, where 714 the access pattern should not change, the checksum provides assurance 715 that the refactoring work has not broken the driver. 716 717 This works by sneaking into the io.h heder for an architecture and 718 redirecting I/O accesses through iotrace's tracing mechanism. 719 720 For now no commands are provided to examine the trace buffer. The 721 format is fairly simple, so 'md' is a reasonable substitute. 722 723 Note: The checksum feature is only useful for I/O regions where the 724 contents do not change outside of software control. Where this is not 725 suitable you can fall back to manually comparing the addresses. It 726 might be useful to enhance tracing to only checksum the accesses and 727 not the data read/written. 728 729config CMD_I2C 730 bool "i2c" 731 help 732 I2C support. 733 734config CMD_LOADB 735 bool "loadb" 736 default y 737 help 738 Load a binary file over serial line. 739 740config CMD_LOADS 741 bool "loads" 742 default y 743 help 744 Load an S-Record file over serial line 745 746config CMD_LOAD_ANDROID 747 bool "load_android" 748 default n 749 depends on ANDROID_BOOT_IMAGE 750 help 751 Load an Android Boot image from storage.
