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