It also maintains a checksum 806 of the trace records (even if space is exhausted) so that the 807 sequence of I/O accesses can be verified. 808 809 When debugging drivers it is useful to see what I/O accesses were 810 done and in what order. 811 812 Even if the individual accesses are of little interest it can be 813 useful to verify that the access pattern is consistent each time 814 an operation is performed. In this case a checksum can be used to 815 characterise the operation of a driver. The checksum can be compared 816 across different runs of the operation to verify that the driver is 817 working properly. 818 819 In particular, when performing major refactoring of the driver, where 820 the access pattern should not change, the checksum provides assurance 821 that the refactoring work has not broken the driver. 822 823 This works by sneaking into the io.h heder for an architecture and 824 redirecting I/O accesses through iotrace's tracing mechanism. 825 826 For now no commands are provided to examine the trace buffer. The 827 format is fairly simple, so 'md' is a reasonable substitute. 828 829 Note: The checksum feature is only useful for I/O regions where the 830 contents do not change outside of software control. Where this is not 831 suitable you can fall back to manually comparing the addresses. It 832 might be useful to enhance tracing to only checksum the accesses and 833 not the data read/written. 834 835 config CMD_I2C 836 bool "i2c" 837 help 838 I2C support. 839 840 config CMD_LOADB 841 bool "loadb" 842 default y 843 help 844 Load a binary file over serial line. 845 846 config CMD_LOADS 847 bool "loads" 848 default y 849 help 850 Load an S-Record file over serial line 851 852 config CMD_LOAD_ANDROID 853 bool "load_android" 854 default n 855 depends on ANDROID_BOOT_IMAGE 856 help 857 Load an Android Boot image from storage.
