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_LOADB 836 bool "loadb" 837 default y 838 help 839 Load a binary file over serial line. 840 841config CMD_LOADS 842 bool "loads" 843 default y 844 help 845 Load an S-Record file over serial line 846 847config CMD_MMC 848 bool "mmc" 849 help 850 MMC memory mapped support. 851 852config CMD_MMC_RPMB 853 bool "Enable support for RPMB in the mmc command" 854 depends on CMD_MMC 855 help 856 Enable the commands for reading, writing and programming the 857 key for the Replay Protection Memory Block partition in eMMC. 858 859config CMD_MMC_SWRITE 860 bool "mmc swrite" 861 depends on CMD_MMC && MMC_WRITE 862 select IMAGE_SPARSE 863 help 864 Enable support for the "mmc swrite" command to write Android sparse 865 images to eMMC. 866 867config CMD_NAND 868 bool "nand" 869 default y if NAND_SUNXI 870 help 871 NAND support. 872 873if CMD_NAND 874config CMD_NAND_TRIMFFS 875 bool "nand write.trimffs" 876 default y if ARCH_SUNXI 877 help 878 Allows one to skip empty pages when flashing something on a NAND. 879 880config CMD_NAND_LOCK_UNLOCK 881 bool "nand lock/unlock" 882 help 883 NAND locking support. 884 885config CMD_NAND_TORTURE 886 bool "nand torture" 887 help 888 NAND torture support. 889 890endif # CMD_NAND 891 892config CMD_NVME 893 bool "nvme" 894 depends on NVME 895 default y if NVME 896 help 897 NVM Express device support 898 899config CMD_MMC_SPI 900 bool "mmc_spi - Set up MMC SPI device" 901 help 902 Provides a way to set up an MMC (Multimedia Card) SPI (Serial 903 Peripheral Interface) device.
