It also maintains a checksum 651 of the trace records (even if space is exhausted) so that the 652 sequence of I/O accesses can be verified. 653 654 When debugging drivers it is useful to see what I/O accesses were 655 done and in what order. 656 657 Even if the individual accesses are of little interest it can be 658 useful to verify that the access pattern is consistent each time 659 an operation is performed. In this case a checksum can be used to 660 characterise the operation of a driver. The checksum can be compared 661 across different runs of the operation to verify that the driver is 662 working properly. 663 664 In particular, when performing major refactoring of the driver, where 665 the access pattern should not change, the checksum provides assurance 666 that the refactoring work has not broken the driver. 667 668 This works by sneaking into the io.h heder for an architecture and 669 redirecting I/O accesses through iotrace's tracing mechanism. 670 671 For now no commands are provided to examine the trace buffer. The 672 format is fairly simple, so 'md' is a reasonable substitute. 673 674 Note: The checksum feature is only useful for I/O regions where the 675 contents do not change outside of software control. Where this is not 676 suitable you can fall back to manually comparing the addresses. It 677 might be useful to enhance tracing to only checksum the accesses and 678 not the data read/written. 679 680config CMD_I2C 681 bool "i2c" 682 help 683 I2C support. 684 685config CMD_LOADB 686 bool "loadb" 687 default y 688 help 689 Load a binary file over serial line. 690 691config CMD_LOADS 692 bool "loads" 693 default y 694 help 695 Load an S-Record file over serial line 696 697config CMD_MMC 698 bool "mmc" 699 help 700 MMC memory mapped support. 701 702config CMD_NAND 703 bool "nand" 704 default y if NAND_SUNXI 705 help 706 NAND support. 707 708if CMD_NAND 709config CMD_NAND_TRIMFFS 710 bool "nand write.trimffs" 711 default y if ARCH_SUNXI 712 help 713 Allows one to skip empty pages when flashing something on a NAND. 714 715config CMD_NAND_LOCK_UNLOCK 716 bool "nand lock/unlock" 717 help 718 NAND locking support. 719 720config CMD_NAND_TORTURE 721 bool "nand torture" 722 help 723 NAND torture support. 724 725endif # CMD_NAND 726 727config CMD_MMC_SPI 728 bool "mmc_spi - Set up MMC SPI device" 729 help 730 Provides a way to set up an MMC (Multimedia Card) SPI (Serial 731 Peripheral Interface) device.
