It also maintains a checksum 715 of the trace records (even if space is exhausted) so that the 716 sequence of I/O accesses can be verified. 717 718 When debugging drivers it is useful to see what I/O accesses were 719 done and in what order. 720 721 Even if the individual accesses are of little interest it can be 722 useful to verify that the access pattern is consistent each time 723 an operation is performed. In this case a checksum can be used to 724 characterise the operation of a driver. The checksum can be compared 725 across different runs of the operation to verify that the driver is 726 working properly. 727 728 In particular, when performing major refactoring of the driver, where 729 the access pattern should not change, the checksum provides assurance 730 that the refactoring work has not broken the driver. 731 732 This works by sneaking into the io.h heder for an architecture and 733 redirecting I/O accesses through iotrace's tracing mechanism. 734 735 For now no commands are provided to examine the trace buffer. The 736 format is fairly simple, so 'md' is a reasonable substitute. 737 738 Note: The checksum feature is only useful for I/O regions where the 739 contents do not change outside of software control. Where this is not 740 suitable you can fall back to manually comparing the addresses. It 741 might be useful to enhance tracing to only checksum the accesses and 742 not the data read/written. 743 744config CMD_I2C 745 bool "i2c" 746 help 747 I2C support. 748 749config CMD_LOADB 750 bool "loadb" 751 default n if ARCH_SUNXI 752 default y 753 help 754 Load a binary file over serial line. 755 756config CMD_LOADS 757 bool "loads" 758 default n if ARCH_SUNXI 759 default y 760 help 761 Load an S-Record file over serial line 762 763config CMD_MMC 764 bool "mmc" 765 help 766 MMC memory mapped support. 767 768config CMD_NAND 769 bool "nand" 770 default y if NAND_SUNXI 771 help 772 NAND support. 773 774if CMD_NAND 775config CMD_NAND_TRIMFFS 776 bool "nand write.trimffs" 777 default y if ARCH_SUNXI 778 help 779 Allows one to skip empty pages when flashing something on a NAND. 780 781config CMD_NAND_LOCK_UNLOCK 782 bool "nand lock/unlock" 783 help 784 NAND locking support. 785 786config CMD_NAND_TORTURE 787 bool "nand torture" 788 help 789 NAND torture support. 790 791endif # CMD_NAND 792 793config CMD_NVME 794 bool "nvme" 795 depends on NVME 796 default y if NVME 797 help 798 NVM Express device support 799 800config CMD_MMC_SPI 801 bool "mmc_spi - Set up MMC SPI device" 802 help 803 Provides a way to set up an MMC (Multimedia Card) SPI (Serial 804 Peripheral Interface) device.
