It also maintains a checksum 702 of the trace records (even if space is exhausted) so that the 703 sequence of I/O accesses can be verified. 704 705 When debugging drivers it is useful to see what I/O accesses were 706 done and in what order. 707 708 Even if the individual accesses are of little interest it can be 709 useful to verify that the access pattern is consistent each time 710 an operation is performed. In this case a checksum can be used to 711 characterise the operation of a driver. The checksum can be compared 712 across different runs of the operation to verify that the driver is 713 working properly. 714 715 In particular, when performing major refactoring of the driver, where 716 the access pattern should not change, the checksum provides assurance 717 that the refactoring work has not broken the driver. 718 719 This works by sneaking into the io.h heder for an architecture and 720 redirecting I/O accesses through iotrace's tracing mechanism. 721 722 For now no commands are provided to examine the trace buffer. The 723 format is fairly simple, so 'md' is a reasonable substitute. 724 725 Note: The checksum feature is only useful for I/O regions where the 726 contents do not change outside of software control. Where this is not 727 suitable you can fall back to manually comparing the addresses. It 728 might be useful to enhance tracing to only checksum the accesses and 729 not the data read/written. 730 731config CMD_I2C 732 bool "i2c" 733 help 734 I2C support. 735 736config CMD_LOADB 737 bool "loadb" 738 default y 739 help 740 Load a binary file over serial line. 741 742config CMD_LOADS 743 bool "loads" 744 default y 745 help 746 Load an S-Record file over serial line 747 748config CMD_MMC 749 bool "mmc" 750 help 751 MMC memory mapped support. 752 753config CMD_NAND 754 bool "nand" 755 default y if NAND_SUNXI 756 help 757 NAND support. 758 759if CMD_NAND 760config CMD_NAND_TRIMFFS 761 bool "nand write.trimffs" 762 default y if ARCH_SUNXI 763 help 764 Allows one to skip empty pages when flashing something on a NAND. 765 766config CMD_NAND_LOCK_UNLOCK 767 bool "nand lock/unlock" 768 help 769 NAND locking support. 770 771config CMD_NAND_TORTURE 772 bool "nand torture" 773 help 774 NAND torture support. 775 776endif # CMD_NAND 777 778config CMD_NVME 779 bool "nvme" 780 depends on NVME 781 default y if NVME 782 help 783 NVM Express device support 784 785config CMD_MMC_SPI 786 bool "mmc_spi - Set up MMC SPI device" 787 help 788 Provides a way to set up an MMC (Multimedia Card) SPI (Serial 789 Peripheral Interface) device.
