It also maintains a checksum 716 of the trace records (even if space is exhausted) so that the 717 sequence of I/O accesses can be verified. 718 719 When debugging drivers it is useful to see what I/O accesses were 720 done and in what order. 721 722 Even if the individual accesses are of little interest it can be 723 useful to verify that the access pattern is consistent each time 724 an operation is performed. In this case a checksum can be used to 725 characterise the operation of a driver. The checksum can be compared 726 across different runs of the operation to verify that the driver is 727 working properly. 728 729 In particular, when performing major refactoring of the driver, where 730 the access pattern should not change, the checksum provides assurance 731 that the refactoring work has not broken the driver. 732 733 This works by sneaking into the io.h heder for an architecture and 734 redirecting I/O accesses through iotrace's tracing mechanism. 735 736 For now no commands are provided to examine the trace buffer. The 737 format is fairly simple, so 'md' is a reasonable substitute. 738 739 Note: The checksum feature is only useful for I/O regions where the 740 contents do not change outside of software control. Where this is not 741 suitable you can fall back to manually comparing the addresses. It 742 might be useful to enhance tracing to only checksum the accesses and 743 not the data read/written. 744 745config CMD_I2C 746 bool "i2c" 747 help 748 I2C support. 749 750config CMD_LOADB 751 bool "loadb" 752 default n if ARCH_SUNXI 753 default y 754 help 755 Load a binary file over serial line. 756 757config CMD_LOADS 758 bool "loads" 759 default n if ARCH_SUNXI 760 default y 761 help 762 Load an S-Record file over serial line 763 764config CMD_MMC 765 bool "mmc" 766 help 767 MMC memory mapped support. 768 769config CMD_NAND 770 bool "nand" 771 default y if NAND_SUNXI 772 help 773 NAND support. 774 775if CMD_NAND 776config CMD_NAND_TRIMFFS 777 bool "nand write.trimffs" 778 default y if ARCH_SUNXI 779 help 780 Allows one to skip empty pages when flashing something on a NAND. 781 782config CMD_NAND_LOCK_UNLOCK 783 bool "nand lock/unlock" 784 help 785 NAND locking support. 786 787config CMD_NAND_TORTURE 788 bool "nand torture" 789 help 790 NAND torture support. 791 792endif # CMD_NAND 793 794config CMD_NVME 795 bool "nvme" 796 depends on NVME 797 default y if NVME 798 help 799 NVM Express device support 800 801config CMD_MMC_SPI 802 bool "mmc_spi - Set up MMC SPI device" 803 help 804 Provides a way to set up an MMC (Multimedia Card) SPI (Serial 805 Peripheral Interface) device.
