In this case a checksum can be used to 805 characterise the operation of a driver. The checksum can be compared 806 across different runs of the operation to verify that the driver is 807 working properly. 808 809 In particular, when performing major refactoring of the driver, where 810 the access pattern should not change, the checksum provides assurance 811 that the refactoring work has not broken the driver. 812 813 This works by sneaking into the io.h heder for an architecture and 814 redirecting I/O accesses through iotrace's tracing mechanism. 815 816 For now no commands are provided to examine the trace buffer. The 817 format is fairly simple, so 'md' is a reasonable substitute. 818 819 Note: The checksum feature is only useful for I/O regions where the 820 contents do not change outside of software control. Where this is not 821 suitable you can fall back to manually comparing the addresses. It 822 might be useful to enhance tracing to only checksum the accesses and 823 not the data read/written. 824 825config CMD_I2C 826 bool "i2c" 827 help 828 I2C support. 829 830config CMD_W1 831 depends on W1 832 default y if W1 833 bool "w1 - Support for Dallas 1-Wire protocol" 834 help 835 Dallas 1-wire protocol support 836 837config CMD_LOADB 838 bool "loadb" 839 default y 840 help 841 Load a binary file over serial line. 842 843config CMD_LOADS 844 bool "loads" 845 default y 846 help 847 Load an S-Record file over serial line 848 849config CMD_MMC 850 bool "mmc" 851 help 852 MMC memory mapped support. 853 854config CMD_MMC_RPMB 855 bool "Enable support for RPMB in the mmc command" 856 depends on CMD_MMC 857 help 858 Enable the commands for reading, writing and programming the 859 key for the Replay Protection Memory Block partition in eMMC. 860 861config CMD_MMC_SWRITE 862 bool "mmc swrite" 863 depends on CMD_MMC && MMC_WRITE 864 select IMAGE_SPARSE 865 help 866 Enable support for the "mmc swrite" command to write Android sparse 867 images to eMMC. 868 869config CMD_NAND 870 bool "nand" 871 default y if NAND_SUNXI 872 help 873 NAND support. 874 875if CMD_NAND 876config CMD_NAND_TRIMFFS 877 bool "nand write.trimffs" 878 default y if ARCH_SUNXI 879 help 880 Allows one to skip empty pages when flashing something on a NAND. 881 882config CMD_NAND_LOCK_UNLOCK 883 bool "nand lock/unlock" 884 help 885 NAND locking support. 886 887config CMD_NAND_TORTURE 888 bool "nand torture" 889 help 890 NAND torture support. 891 892endif # CMD_NAND 893 894config CMD_NVME 895 bool "nvme" 896 depends on NVME 897 default y if NVME 898 help 899 NVM Express device support 900 901config CMD_MMC_SPI 902 bool "mmc_spi - Set up MMC SPI device" 903 help 904 Provides a way to set up an MMC (Multimedia Card) SPI (Serial 905 Peripheral Interface) device.
