It also maintains a checksum 636 of the trace records (even if space is exhausted) so that the 637 sequence of I/O accesses can be verified. 638 639 When debugging drivers it is useful to see what I/O accesses were 640 done and in what order. 641 642 Even if the individual accesses are of little interest it can be 643 useful to verify that the access pattern is consistent each time 644 an operation is performed. In this case a checksum can be used to 645 characterise the operation of a driver. The checksum can be compared 646 across different runs of the operation to verify that the driver is 647 working properly. 648 649 In particular, when performing major refactoring of the driver, where 650 the access pattern should not change, the checksum provides assurance 651 that the refactoring work has not broken the driver. 652 653 This works by sneaking into the io.h heder for an architecture and 654 redirecting I/O accesses through iotrace's tracing mechanism. 655 656 For now no commands are provided to examine the trace buffer. The 657 format is fairly simple, so 'md' is a reasonable substitute. 658 659 Note: The checksum feature is only useful for I/O regions where the 660 contents do not change outside of software control. Where this is not 661 suitable you can fall back to manually comparing the addresses. It 662 might be useful to enhance tracing to only checksum the accesses and 663 not the data read/written. 664 665config CMD_I2C 666 bool "i2c" 667 help 668 I2C support. 669 670config CMD_LOADB 671 bool "loadb" 672 default y 673 help 674 Load a binary file over serial line. 675 676config CMD_LOADS 677 bool "loads" 678 default y 679 help 680 Load an S-Record file over serial line 681 682config CMD_MMC 683 bool "mmc" 684 help 685 MMC memory mapped support. 686 687config CMD_NAND 688 bool "nand" 689 default y if NAND_SUNXI 690 help 691 NAND support. 692 693if CMD_NAND 694config CMD_NAND_TRIMFFS 695 bool "nand write.trimffs" 696 default y if ARCH_SUNXI 697 help 698 Allows one to skip empty pages when flashing something on a NAND. 699 700config CMD_NAND_LOCK_UNLOCK 701 bool "nand lock/unlock" 702 help 703 NAND locking support. 704 705config CMD_NAND_TORTURE 706 bool "nand torture" 707 help 708 NAND torture support. 709 710endif # CMD_NAND 711 712config CMD_MMC_SPI 713 bool "mmc_spi - Set up MMC SPI device" 714 help 715 Provides a way to set up an MMC (Multimedia Card) SPI (Serial 716 Peripheral Interface) device.
