It also maintains a checksum 670 of the trace records (even if space is exhausted) so that the 671 sequence of I/O accesses can be verified. 672 673 When debugging drivers it is useful to see what I/O accesses were 674 done and in what order. 675 676 Even if the individual accesses are of little interest it can be 677 useful to verify that the access pattern is consistent each time 678 an operation is performed. In this case a checksum can be used to 679 characterise the operation of a driver. The checksum can be compared 680 across different runs of the operation to verify that the driver is 681 working properly. 682 683 In particular, when performing major refactoring of the driver, where 684 the access pattern should not change, the checksum provides assurance 685 that the refactoring work has not broken the driver. 686 687 This works by sneaking into the io.h heder for an architecture and 688 redirecting I/O accesses through iotrace's tracing mechanism. 689 690 For now no commands are provided to examine the trace buffer. The 691 format is fairly simple, so 'md' is a reasonable substitute. 692 693 Note: The checksum feature is only useful for I/O regions where the 694 contents do not change outside of software control. Where this is not 695 suitable you can fall back to manually comparing the addresses. It 696 might be useful to enhance tracing to only checksum the accesses and 697 not the data read/written. 698 699config CMD_I2C 700 bool "i2c" 701 help 702 I2C support. 703 704config CMD_LOADB 705 bool "loadb" 706 default y 707 help 708 Load a binary file over serial line. 709 710config CMD_LOADS 711 bool "loads" 712 default y 713 help 714 Load an S-Record file over serial line 715 716config CMD_MMC 717 bool "mmc" 718 help 719 MMC memory mapped support. 720 721config CMD_NAND 722 bool "nand" 723 default y if NAND_SUNXI 724 help 725 NAND support. 726 727if CMD_NAND 728config CMD_NAND_TRIMFFS 729 bool "nand write.trimffs" 730 default y if ARCH_SUNXI 731 help 732 Allows one to skip empty pages when flashing something on a NAND. 733 734config CMD_NAND_LOCK_UNLOCK 735 bool "nand lock/unlock" 736 help 737 NAND locking support. 738 739config CMD_NAND_TORTURE 740 bool "nand torture" 741 help 742 NAND torture support. 743 744endif # CMD_NAND 745 746config CMD_MMC_SPI 747 bool "mmc_spi - Set up MMC SPI device" 748 help 749 Provides a way to set up an MMC (Multimedia Card) SPI (Serial 750 Peripheral Interface) device.
