It also maintains a checksum 724 of the trace records (even if space is exhausted) so that the 725 sequence of I/O accesses can be verified. 726 727 When debugging drivers it is useful to see what I/O accesses were 728 done and in what order. 729 730 Even if the individual accesses are of little interest it can be 731 useful to verify that the access pattern is consistent each time 732 an operation is performed. In this case a checksum can be used to 733 characterise the operation of a driver. The checksum can be compared 734 across different runs of the operation to verify that the driver is 735 working properly. 736 737 In particular, when performing major refactoring of the driver, where 738 the access pattern should not change, the checksum provides assurance 739 that the refactoring work has not broken the driver. 740 741 This works by sneaking into the io.h heder for an architecture and 742 redirecting I/O accesses through iotrace's tracing mechanism. 743 744 For now no commands are provided to examine the trace buffer. The 745 format is fairly simple, so 'md' is a reasonable substitute. 746 747 Note: The checksum feature is only useful for I/O regions where the 748 contents do not change outside of software control. Where this is not 749 suitable you can fall back to manually comparing the addresses. It 750 might be useful to enhance tracing to only checksum the accesses and 751 not the data read/written. 752 753config CMD_I2C 754 bool "i2c" 755 help 756 I2C support. 757 758config CMD_LOADB 759 bool "loadb" 760 default n if ARCH_SUNXI 761 default y 762 help 763 Load a binary file over serial line. 764 765config CMD_LOADS 766 bool "loads" 767 default n if ARCH_SUNXI 768 default y 769 help 770 Load an S-Record file over serial line 771 772config CMD_MMC 773 bool "mmc" 774 help 775 MMC memory mapped support. 776 777config CMD_NAND 778 bool "nand" 779 default y if NAND_SUNXI 780 help 781 NAND support. 782 783if CMD_NAND 784config CMD_NAND_TRIMFFS 785 bool "nand write.trimffs" 786 default y if ARCH_SUNXI 787 help 788 Allows one to skip empty pages when flashing something on a NAND. 789 790config CMD_NAND_LOCK_UNLOCK 791 bool "nand lock/unlock" 792 help 793 NAND locking support. 794 795config CMD_NAND_TORTURE 796 bool "nand torture" 797 help 798 NAND torture support. 799 800endif # CMD_NAND 801 802config CMD_NVME 803 bool "nvme" 804 depends on NVME 805 default y if NVME 806 help 807 NVM Express device support 808 809config CMD_MMC_SPI 810 bool "mmc_spi - Set up MMC SPI device" 811 help 812 Provides a way to set up an MMC (Multimedia Card) SPI (Serial 813 Peripheral Interface) device.
