It also maintains a checksum 661 of the trace records (even if space is exhausted) so that the 662 sequence of I/O accesses can be verified. 663 664 When debugging drivers it is useful to see what I/O accesses were 665 done and in what order. 666 667 Even if the individual accesses are of little interest it can be 668 useful to verify that the access pattern is consistent each time 669 an operation is performed. In this case a checksum can be used to 670 characterise the operation of a driver. The checksum can be compared 671 across different runs of the operation to verify that the driver is 672 working properly. 673 674 In particular, when performing major refactoring of the driver, where 675 the access pattern should not change, the checksum provides assurance 676 that the refactoring work has not broken the driver. 677 678 This works by sneaking into the io.h heder for an architecture and 679 redirecting I/O accesses through iotrace's tracing mechanism. 680 681 For now no commands are provided to examine the trace buffer. The 682 format is fairly simple, so 'md' is a reasonable substitute. 683 684 Note: The checksum feature is only useful for I/O regions where the 685 contents do not change outside of software control. Where this is not 686 suitable you can fall back to manually comparing the addresses. It 687 might be useful to enhance tracing to only checksum the accesses and 688 not the data read/written. 689 690config CMD_I2C 691 bool "i2c" 692 help 693 I2C support. 694 695config CMD_LOADB 696 bool "loadb" 697 default y 698 help 699 Load a binary file over serial line. 700 701config CMD_LOADS 702 bool "loads" 703 default y 704 help 705 Load an S-Record file over serial line 706 707config CMD_MMC 708 bool "mmc" 709 help 710 MMC memory mapped support. 711 712config CMD_NAND 713 bool "nand" 714 default y if NAND_SUNXI 715 help 716 NAND support. 717 718if CMD_NAND 719config CMD_NAND_TRIMFFS 720 bool "nand write.trimffs" 721 default y if ARCH_SUNXI 722 help 723 Allows one to skip empty pages when flashing something on a NAND. 724 725config CMD_NAND_LOCK_UNLOCK 726 bool "nand lock/unlock" 727 help 728 NAND locking support. 729 730config CMD_NAND_TORTURE 731 bool "nand torture" 732 help 733 NAND torture support. 734 735endif # CMD_NAND 736 737config CMD_MMC_SPI 738 bool "mmc_spi - Set up MMC SPI device" 739 help 740 Provides a way to set up an MMC (Multimedia Card) SPI (Serial 741 Peripheral Interface) device.
