It also maintains a checksum 712 of the trace records (even if space is exhausted) so that the 713 sequence of I/O accesses can be verified. 714 715 When debugging drivers it is useful to see what I/O accesses were 716 done and in what order. 717 718 Even if the individual accesses are of little interest it can be 719 useful to verify that the access pattern is consistent each time 720 an operation is performed. In this case a checksum can be used to 721 characterise the operation of a driver. The checksum can be compared 722 across different runs of the operation to verify that the driver is 723 working properly. 724 725 In particular, when performing major refactoring of the driver, where 726 the access pattern should not change, the checksum provides assurance 727 that the refactoring work has not broken the driver. 728 729 This works by sneaking into the io.h heder for an architecture and 730 redirecting I/O accesses through iotrace's tracing mechanism. 731 732 For now no commands are provided to examine the trace buffer. The 733 format is fairly simple, so 'md' is a reasonable substitute. 734 735 Note: The checksum feature is only useful for I/O regions where the 736 contents do not change outside of software control. Where this is not 737 suitable you can fall back to manually comparing the addresses. It 738 might be useful to enhance tracing to only checksum the accesses and 739 not the data read/written. 740 741config CMD_I2C 742 bool "i2c" 743 help 744 I2C support. 745 746config CMD_LOADB 747 bool "loadb" 748 default y 749 help 750 Load a binary file over serial line. 751 752config CMD_LOADS 753 bool "loads" 754 default y 755 help 756 Load an S-Record file over serial line 757 758config CMD_LOAD_ANDROID 759 bool "load_android" 760 default n 761 depends on ANDROID_BOOT_IMAGE 762 help 763 Load an Android Boot image from storage.
