It also maintains a checksum 713 of the trace records (even if space is exhausted) so that the 714 sequence of I/O accesses can be verified. 715 716 When debugging drivers it is useful to see what I/O accesses were 717 done and in what order. 718 719 Even if the individual accesses are of little interest it can be 720 useful to verify that the access pattern is consistent each time 721 an operation is performed. In this case a checksum can be used to 722 characterise the operation of a driver. The checksum can be compared 723 across different runs of the operation to verify that the driver is 724 working properly. 725 726 In particular, when performing major refactoring of the driver, where 727 the access pattern should not change, the checksum provides assurance 728 that the refactoring work has not broken the driver. 729 730 This works by sneaking into the io.h heder for an architecture and 731 redirecting I/O accesses through iotrace's tracing mechanism. 732 733 For now no commands are provided to examine the trace buffer. The 734 format is fairly simple, so 'md' is a reasonable substitute. 735 736 Note: The checksum feature is only useful for I/O regions where the 737 contents do not change outside of software control. Where this is not 738 suitable you can fall back to manually comparing the addresses. It 739 might be useful to enhance tracing to only checksum the accesses and 740 not the data read/written. 741 742config CMD_I2C 743 bool "i2c" 744 help 745 I2C support. 746 747config CMD_LOADB 748 bool "loadb" 749 default y 750 help 751 Load a binary file over serial line. 752 753config CMD_LOADS 754 bool "loads" 755 default y 756 help 757 Load an S-Record file over serial line 758 759config CMD_MMC 760 bool "mmc" 761 help 762 MMC memory mapped support. 763 764config CMD_NAND 765 bool "nand" 766 default y if NAND_SUNXI 767 help 768 NAND support. 769 770if CMD_NAND 771config CMD_NAND_TRIMFFS 772 bool "nand write.trimffs" 773 default y if ARCH_SUNXI 774 help 775 Allows one to skip empty pages when flashing something on a NAND. 776 777config CMD_NAND_LOCK_UNLOCK 778 bool "nand lock/unlock" 779 help 780 NAND locking support. 781 782config CMD_NAND_TORTURE 783 bool "nand torture" 784 help 785 NAND torture support. 786 787endif # CMD_NAND 788 789config CMD_NVME 790 bool "nvme" 791 depends on NVME 792 default y if NVME 793 help 794 NVM Express device support 795 796config CMD_MMC_SPI 797 bool "mmc_spi - Set up MMC SPI device" 798 help 799 Provides a way to set up an MMC (Multimedia Card) SPI (Serial 800 Peripheral Interface) device.
