It also maintains a checksum 707 of the trace records (even if space is exhausted) so that the 708 sequence of I/O accesses can be verified. 709 710 When debugging drivers it is useful to see what I/O accesses were 711 done and in what order. 712 713 Even if the individual accesses are of little interest it can be 714 useful to verify that the access pattern is consistent each time 715 an operation is performed. In this case a checksum can be used to 716 characterise the operation of a driver. The checksum can be compared 717 across different runs of the operation to verify that the driver is 718 working properly. 719 720 In particular, when performing major refactoring of the driver, where 721 the access pattern should not change, the checksum provides assurance 722 that the refactoring work has not broken the driver. 723 724 This works by sneaking into the io.h heder for an architecture and 725 redirecting I/O accesses through iotrace's tracing mechanism. 726 727 For now no commands are provided to examine the trace buffer. The 728 format is fairly simple, so 'md' is a reasonable substitute. 729 730 Note: The checksum feature is only useful for I/O regions where the 731 contents do not change outside of software control. Where this is not 732 suitable you can fall back to manually comparing the addresses. It 733 might be useful to enhance tracing to only checksum the accesses and 734 not the data read/written. 735 736config CMD_I2C 737 bool "i2c" 738 help 739 I2C support. 740 741config CMD_LOADB 742 bool "loadb" 743 default y 744 help 745 Load a binary file over serial line. 746 747config CMD_LOADS 748 bool "loads" 749 default y 750 help 751 Load an S-Record file over serial line 752 753config CMD_LOAD_ANDROID 754 bool "load_android" 755 default n 756 depends on ANDROID_BOOT_IMAGE 757 help 758 Load an Android Boot image from storage.
