It also maintains a checksum 812 of the trace records (even if space is exhausted) so that the 813 sequence of I/O accesses can be verified. 814 815 When debugging drivers it is useful to see what I/O accesses were 816 done and in what order. 817 818 Even if the individual accesses are of little interest it can be 819 useful to verify that the access pattern is consistent each time 820 an operation is performed. In this case a checksum can be used to 821 characterise the operation of a driver. The checksum can be compared 822 across different runs of the operation to verify that the driver is 823 working properly. 824 825 In particular, when performing major refactoring of the driver, where 826 the access pattern should not change, the checksum provides assurance 827 that the refactoring work has not broken the driver. 828 829 This works by sneaking into the io.h heder for an architecture and 830 redirecting I/O accesses through iotrace's tracing mechanism. 831 832 For now no commands are provided to examine the trace buffer. The 833 format is fairly simple, so 'md' is a reasonable substitute. 834 835 Note: The checksum feature is only useful for I/O regions where the 836 contents do not change outside of software control. Where this is not 837 suitable you can fall back to manually comparing the addresses. It 838 might be useful to enhance tracing to only checksum the accesses and 839 not the data read/written. 840 841config CMD_I2C 842 bool "i2c" 843 help 844 I2C support. 845 846config CMD_W1 847 depends on W1 848 default y if W1 849 bool "w1 - Support for Dallas 1-Wire protocol" 850 help 851 Dallas 1-wire protocol support 852 853config CMD_LOADB 854 bool "loadb" 855 default y 856 help 857 Load a binary file over serial line. 858 859config CMD_LOADS 860 bool "loads" 861 default y 862 help 863 Load an S-Record file over serial line 864 865config CMD_MMC 866 bool "mmc" 867 help 868 MMC memory mapped support. 869 870config CMD_MMC_RPMB 871 bool "Enable support for RPMB in the mmc command" 872 depends on CMD_MMC 873 help 874 Enable the commands for reading, writing and programming the 875 key for the Replay Protection Memory Block partition in eMMC. 876 877config CMD_MMC_SWRITE 878 bool "mmc swrite" 879 depends on CMD_MMC && MMC_WRITE 880 select IMAGE_SPARSE 881 help 882 Enable support for the "mmc swrite" command to write Android sparse 883 images to eMMC. 884 885config CMD_MTD 886 bool "mtd" 887 select MTD_PARTITIONS 888 help 889 MTD commands support. 890 891config CMD_NAND 892 bool "nand" 893 default y if NAND_SUNXI 894 help 895 NAND support. 896 897if CMD_NAND 898config CMD_NAND_TRIMFFS 899 bool "nand write.trimffs" 900 default y if ARCH_SUNXI 901 help 902 Allows one to skip empty pages when flashing something on a NAND. 903 904config CMD_NAND_LOCK_UNLOCK 905 bool "nand lock/unlock" 906 help 907 NAND locking support. 908 909config CMD_NAND_TORTURE 910 bool "nand torture" 911 help 912 NAND torture support. 913 914endif # CMD_NAND 915 916config CMD_NVME 917 bool "nvme" 918 depends on NVME 919 default y if NVME 920 help 921 NVM Express device support 922 923config CMD_MMC_SPI 924 bool "mmc_spi - Set up MMC SPI device" 925 help 926 Provides a way to set up an MMC (Multimedia Card) SPI (Serial 927 Peripheral Interface) device.
