In this case a checksum can be used to 806 characterise the operation of a driver. The checksum can be compared 807 across different runs of the operation to verify that the driver is 808 working properly. 809 810 In particular, when performing major refactoring of the driver, where 811 the access pattern should not change, the checksum provides assurance 812 that the refactoring work has not broken the driver. 813 814 This works by sneaking into the io.h heder for an architecture and 815 redirecting I/O accesses through iotrace's tracing mechanism. 816 817 For now no commands are provided to examine the trace buffer. The 818 format is fairly simple, so 'md' is a reasonable substitute. 819 820 Note: The checksum feature is only useful for I/O regions where the 821 contents do not change outside of software control. Where this is not 822 suitable you can fall back to manually comparing the addresses. It 823 might be useful to enhance tracing to only checksum the accesses and 824 not the data read/written. 825 826config CMD_I2C 827 bool "i2c" 828 help 829 I2C support. 830 831config CMD_W1 832 depends on W1 833 default y if W1 834 bool "w1 - Support for Dallas 1-Wire protocol" 835 help 836 Dallas 1-wire protocol support 837 838config CMD_LOADB 839 bool "loadb" 840 default y 841 help 842 Load a binary file over serial line. 843 844config CMD_LOADS 845 bool "loads" 846 default y 847 help 848 Load an S-Record file over serial line 849 850config CMD_MMC 851 bool "mmc" 852 help 853 MMC memory mapped support. 854 855config CMD_MMC_RPMB 856 bool "Enable support for RPMB in the mmc command" 857 depends on CMD_MMC 858 help 859 Enable the commands for reading, writing and programming the 860 key for the Replay Protection Memory Block partition in eMMC. 861 862config CMD_MMC_SWRITE 863 bool "mmc swrite" 864 depends on CMD_MMC && MMC_WRITE 865 select IMAGE_SPARSE 866 help 867 Enable support for the "mmc swrite" command to write Android sparse 868 images to eMMC. 869 870config CMD_MTD 871 bool "mtd" 872 select MTD_PARTITIONS 873 help 874 MTD commands support. 875 876config CMD_NAND 877 bool "nand" 878 default y if NAND_SUNXI 879 help 880 NAND support. 881 882if CMD_NAND 883config CMD_NAND_TRIMFFS 884 bool "nand write.trimffs" 885 default y if ARCH_SUNXI 886 help 887 Allows one to skip empty pages when flashing something on a NAND. 888 889config CMD_NAND_LOCK_UNLOCK 890 bool "nand lock/unlock" 891 help 892 NAND locking support. 893 894config CMD_NAND_TORTURE 895 bool "nand torture" 896 help 897 NAND torture support. 898 899endif # CMD_NAND 900 901config CMD_NVME 902 bool "nvme" 903 depends on NVME 904 default y if NVME 905 help 906 NVM Express device support 907 908config CMD_MMC_SPI 909 bool "mmc_spi - Set up MMC SPI device" 910 help 911 Provides a way to set up an MMC (Multimedia Card) SPI (Serial 912 Peripheral Interface) device.
