It also maintains a checksum 807 of the trace records (even if space is exhausted) so that the 808 sequence of I/O accesses can be verified. 809 810 When debugging drivers it is useful to see what I/O accesses were 811 done and in what order. 812 813 Even if the individual accesses are of little interest it can be 814 useful to verify that the access pattern is consistent each time 815 an operation is performed. In this case a checksum can be used to 816 characterise the operation of a driver. The checksum can be compared 817 across different runs of the operation to verify that the driver is 818 working properly. 819 820 In particular, when performing major refactoring of the driver, where 821 the access pattern should not change, the checksum provides assurance 822 that the refactoring work has not broken the driver. 823 824 This works by sneaking into the io.h heder for an architecture and 825 redirecting I/O accesses through iotrace's tracing mechanism. 826 827 For now no commands are provided to examine the trace buffer. The 828 format is fairly simple, so 'md' is a reasonable substitute. 829 830 Note: The checksum feature is only useful for I/O regions where the 831 contents do not change outside of software control. Where this is not 832 suitable you can fall back to manually comparing the addresses. It 833 might be useful to enhance tracing to only checksum the accesses and 834 not the data read/written. 835 836config CMD_I2C 837 bool "i2c" 838 help 839 I2C support. 840 841config CMD_W1 842 depends on W1 843 default y if W1 844 bool "w1 - Support for Dallas 1-Wire protocol" 845 help 846 Dallas 1-wire protocol support 847 848config CMD_LOADB 849 bool "loadb" 850 default y 851 help 852 Load a binary file over serial line. 853 854config CMD_LOADS 855 bool "loads" 856 default y 857 help 858 Load an S-Record file over serial line 859 860config CMD_MMC 861 bool "mmc" 862 help 863 MMC memory mapped support. 864 865config CMD_MMC_RPMB 866 bool "Enable support for RPMB in the mmc command" 867 depends on CMD_MMC 868 help 869 Enable the commands for reading, writing and programming the 870 key for the Replay Protection Memory Block partition in eMMC. 871 872config CMD_MMC_SWRITE 873 bool "mmc swrite" 874 depends on CMD_MMC && MMC_WRITE 875 select IMAGE_SPARSE 876 help 877 Enable support for the "mmc swrite" command to write Android sparse 878 images to eMMC. 879 880config CMD_MTD 881 bool "mtd" 882 select MTD_PARTITIONS 883 help 884 MTD commands support. 885 886config CMD_NAND 887 bool "nand" 888 default y if NAND_SUNXI 889 help 890 NAND support. 891 892if CMD_NAND 893config CMD_NAND_TRIMFFS 894 bool "nand write.trimffs" 895 default y if ARCH_SUNXI 896 help 897 Allows one to skip empty pages when flashing something on a NAND. 898 899config CMD_NAND_LOCK_UNLOCK 900 bool "nand lock/unlock" 901 help 902 NAND locking support. 903 904config CMD_NAND_TORTURE 905 bool "nand torture" 906 help 907 NAND torture support. 908 909endif # CMD_NAND 910 911config CMD_NVME 912 bool "nvme" 913 depends on NVME 914 default y if NVME 915 help 916 NVM Express device support 917 918config CMD_MMC_SPI 919 bool "mmc_spi - Set up MMC SPI device" 920 help 921 Provides a way to set up an MMC (Multimedia Card) SPI (Serial 922 Peripheral Interface) device.
