It also maintains a checksum 1004 of the trace records (even if space is exhausted) so that the 1005 sequence of I/O accesses can be verified. 1006 1007 When debugging drivers it is useful to see what I/O accesses were 1008 done and in what order. 1009 1010 Even if the individual accesses are of little interest it can be 1011 useful to verify that the access pattern is consistent each time 1012 an operation is performed. In this case a checksum can be used to 1013 characterise the operation of a driver. The checksum can be compared 1014 across different runs of the operation to verify that the driver is 1015 working properly. 1016 1017 In particular, when performing major refactoring of the driver, where 1018 the access pattern should not change, the checksum provides assurance 1019 that the refactoring work has not broken the driver. 1020 1021 This works by sneaking into the io.h heder for an architecture and 1022 redirecting I/O accesses through iotrace's tracing mechanism. 1023 1024 For now no commands are provided to examine the trace buffer. The 1025 format is fairly simple, so 'md' is a reasonable substitute. 1026 1027 Note: The checksum feature is only useful for I/O regions where the 1028 contents do not change outside of software control. Where this is not 1029 suitable you can fall back to manually comparing the addresses. It 1030 might be useful to enhance tracing to only checksum the accesses and 1031 not the data read/written. 1032 1033config CMD_I2C 1034 bool "i2c" 1035 help 1036 I2C support. 1037 1038config CMD_W1 1039 depends on W1 1040 default y if W1 1041 bool "w1 - Support for Dallas 1-Wire protocol" 1042 help 1043 Dallas 1-wire protocol support 1044 1045config CMD_LOADB 1046 bool "loadb" 1047 default y 1048 help 1049 Load a binary file over serial line. 1050 1051config CMD_LOADS 1052 bool "loads" 1053 default y 1054 help 1055 Load an S-Record file over serial line 1056 1057config CMD_LSBLK 1058 depends on BLK 1059 bool "lsblk - list block drivers and devices" 1060 help 1061 Print list of available block device drivers, and for each, the list 1062 of known block devices. 1063 1064config CMD_MBR 1065 bool "MBR (Master Boot Record) command" 1066 select DOS_PARTITION 1067 select HAVE_BLOCK_DEVICE 1068 help 1069 Enable the 'mbr' command to ready and write MBR (Master Boot Record) 1070 style partition tables. 1071 1072config CMD_MISC 1073 bool "misc" 1074 depends on MISC 1075 help 1076 Enable the command "misc" for accessing miscellaneous devices with 1077 a MISC uclass driver.
