It also maintains a checksum 745 of the trace records (even if space is exhausted) so that the 746 sequence of I/O accesses can be verified. 747 748 When debugging drivers it is useful to see what I/O accesses were 749 done and in what order. 750 751 Even if the individual accesses are of little interest it can be 752 useful to verify that the access pattern is consistent each time 753 an operation is performed. In this case a checksum can be used to 754 characterise the operation of a driver. The checksum can be compared 755 across different runs of the operation to verify that the driver is 756 working properly. 757 758 In particular, when performing major refactoring of the driver, where 759 the access pattern should not change, the checksum provides assurance 760 that the refactoring work has not broken the driver. 761 762 This works by sneaking into the io.h heder for an architecture and 763 redirecting I/O accesses through iotrace's tracing mechanism. 764 765 For now no commands are provided to examine the trace buffer. The 766 format is fairly simple, so 'md' is a reasonable substitute. 767 768 Note: The checksum feature is only useful for I/O regions where the 769 contents do not change outside of software control. Where this is not 770 suitable you can fall back to manually comparing the addresses. It 771 might be useful to enhance tracing to only checksum the accesses and 772 not the data read/written. 773 774config CMD_I2C 775 bool "i2c" 776 help 777 I2C support. 778 779config CMD_LOADB 780 bool "loadb" 781 default y 782 help 783 Load a binary file over serial line. 784 785config CMD_LOADS 786 bool "loads" 787 default y 788 help 789 Load an S-Record file over serial line 790 791config CMD_LOAD_ANDROID 792 bool "load_android" 793 default n 794 depends on ANDROID_BOOT_IMAGE 795 help 796 Load an Android Boot image from storage.
