It also enables the 'diskboot' command which 803 permits booting from an IDE drive. 804 805config CMD_IO 806 bool "io - Support for performing I/O accesses" 807 help 808 Provides an 'iod' command to display I/O space and an 'iow' command 809 to write values to the I/O space. This can be useful for manually 810 checking the state of devices during boot when debugging device 811 drivers, etc. 812 813config CMD_IOTRACE 814 bool "iotrace - Support for tracing I/O activity" 815 help 816 Provides an 'iotrace' command which supports recording I/O reads and 817 writes in a trace buffer in memory . It also maintains a checksum 818 of the trace records (even if space is exhausted) so that the 819 sequence of I/O accesses can be verified. 820 821 When debugging drivers it is useful to see what I/O accesses were 822 done and in what order. 823 824 Even if the individual accesses are of little interest it can be 825 useful to verify that the access pattern is consistent each time 826 an operation is performed. In this case a checksum can be used to 827 characterise the operation of a driver. The checksum can be compared 828 across different runs of the operation to verify that the driver is 829 working properly. 830 831 In particular, when performing major refactoring of the driver, where 832 the access pattern should not change, the checksum provides assurance 833 that the refactoring work has not broken the driver. 834 835 This works by sneaking into the io.h heder for an architecture and 836 redirecting I/O accesses through iotrace's tracing mechanism. 837 838 For now no commands are provided to examine the trace buffer. The 839 format is fairly simple, so 'md' is a reasonable substitute. 840 841 Note: The checksum feature is only useful for I/O regions where the 842 contents do not change outside of software control. Where this is not 843 suitable you can fall back to manually comparing the addresses. It 844 might be useful to enhance tracing to only checksum the accesses and 845 not the data read/written. 846 847config CMD_I2C 848 bool "i2c" 849 help 850 I2C support. 851 852config CMD_W1 853 depends on W1 854 default y if W1 855 bool "w1 - Support for Dallas 1-Wire protocol" 856 help 857 Dallas 1-wire protocol support 858 859config CMD_LOADB 860 bool "loadb" 861 default y 862 help 863 Load a binary file over serial line. 864 865config CMD_LOADS 866 bool "loads" 867 default y 868 help 869 Load an S-Record file over serial line 870 871config CMD_MMC 872 bool "mmc" 873 help 874 MMC memory mapped support. 875 876config CMD_MMC_RPMB 877 bool "Enable support for RPMB in the mmc command" 878 depends on CMD_MMC 879 help 880 Enable the commands for reading, writing and programming the 881 key for the Replay Protection Memory Block partition in eMMC. 882 883config CMD_MMC_SWRITE 884 bool "mmc swrite" 885 depends on CMD_MMC && MMC_WRITE 886 select IMAGE_SPARSE 887 help 888 Enable support for the "mmc swrite" command to write Android sparse 889 images to eMMC. 890 891config CMD_MTD 892 bool "mtd" 893 select MTD_PARTITIONS 894 help 895 MTD commands support. 896 897config CMD_NAND 898 bool "nand" 899 default y if NAND_SUNXI 900 help 901 NAND support. 902 903if CMD_NAND 904config CMD_NAND_TRIMFFS 905 bool "nand write.trimffs" 906 default y if ARCH_SUNXI 907 help 908 Allows one to skip empty pages when flashing something on a NAND. 909 910config CMD_NAND_LOCK_UNLOCK 911 bool "nand lock/unlock" 912 help 913 NAND locking support. 914 915config CMD_NAND_TORTURE 916 bool "nand torture" 917 help 918 NAND torture support. 919 920endif # CMD_NAND 921 922config CMD_NVME 923 bool "nvme" 924 depends on NVME 925 default y if NVME 926 help 927 NVM Express device support 928 929config CMD_MMC_SPI 930 bool "mmc_spi - Set up MMC SPI device" 931 help 932 Provides a way to set up an MMC (Multimedia Card) SPI (Serial 933 Peripheral Interface) device.
