It also maintains a checksum 540 of the trace records (even if space is exhausted) so that the 541 sequence of I/O accesses can be verified. 542 543 When debugging drivers it is useful to see what I/O accesses were 544 done and in what order. 545 546 Even if the individual accesses are of little interest it can be 547 useful to verify that the access pattern is consistent each time 548 an operation is performed. In this case a checksum can be used to 549 characterise the operation of a driver. The checksum can be compared 550 across different runs of the operation to verify that the driver is 551 working properly. 552 553 In particular, when performing major refactoring of the driver, where 554 the access pattern should not change, the checksum provides assurance 555 that the refactoring work has not broken the driver. 556 557 This works by sneaking into the io.h heder for an architecture and 558 redirecting I/O accesses through iotrace's tracing mechanism. 559 560 For now no commands are provided to examine the trace buffer. The 561 format is fairly simple, so 'md' is a reasonable substitute. 562 563 Note: The checksum feature is only useful for I/O regions where the 564 contents do not change outside of software control. Where this is not 565 suitable you can fall back to manually comparing the addresses. It 566 might be useful to enhance tracing to only checksum the accesses and 567 not the data read/written. 568 569config CMD_LOADB 570 bool "loadb" 571 default y 572 help 573 Load a binary file over serial line. 574 575config CMD_LOADS 576 bool "loads" 577 default y 578 help 579 Load an S-Record file over serial line 580 581config CMD_FLASH 582 bool "flinfo, erase, protect" 583 default y 584 help 585 NOR flash support. 586 flinfo - print FLASH memory information 587 erase - FLASH memory 588 protect - enable or disable FLASH write protection 589 590config CMD_GPT 591 bool "GPT (GUID Partition Table) command" 592 select PARTITION_UUIDS 593 select EFI_PARTITION 594 help 595 Enable the 'gpt' command to ready and write GPT style partition 596 tables. 597 598config CMD_GPT_RENAME 599 bool "GPT partition renaming commands" 600 depends on CMD_GPT 601 help 602 Enables the 'gpt' command to interchange names on two GPT 603 partitions via the 'gpt swap' command or to rename single 604 partitions via the 'rename' command. 605 606config CMD_ARMFLASH 607 #depends on FLASH_CFI_DRIVER 608 bool "armflash" 609 help 610 ARM Ltd reference designs flash partition access 611 612config CMD_MMC 613 bool "mmc" 614 help 615 MMC memory mapped support. 616 617config CMD_NAND 618 bool "nand" 619 default y if NAND_SUNXI 620 help 621 NAND support. 622 623if CMD_NAND 624config CMD_NAND_TRIMFFS 625 bool "nand write.trimffs" 626 default y if ARCH_SUNXI 627 help 628 Allows one to skip empty pages when flashing something on a NAND. 629 630config CMD_NAND_LOCK_UNLOCK 631 bool "nand lock/unlock" 632 help 633 NAND locking support. 634 635config CMD_NAND_TORTURE 636 bool "nand torture" 637 help 638 NAND torture support. 639 640endif # CMD_NAND 641 642config CMD_PART 643 bool "part" 644 select PARTITION_UUIDS 645 help 646 Read and display information about the partition table on 647 various media. 648 649config CMD_SF 650 bool "sf" 651 help 652 SPI Flash support 653 654config CMD_SPI 655 bool "sspi" 656 help 657 SPI utility command. 658 659config CMD_I2C 660 bool "i2c" 661 help 662 I2C support. 663 664config CMD_USB 665 bool "usb" 666 help 667 USB support. 668 669config CMD_DFU 670 bool "dfu" 671 select USB_FUNCTION_DFU 672 help 673 Enables the command "dfu" which is used to have U-Boot create a DFU 674 class device via USB. 675 676config CMD_USB_MASS_STORAGE 677 bool "UMS usb mass storage" 678 help 679 USB mass storage support 680 681config CMD_FPGA 682 bool "fpga" 683 default y 684 help 685 FPGA support. 686 687config CMD_FPGA_LOADBP 688 bool "fpga loadbp - load partial bitstream (Xilinx only)" 689 depends on CMD_FPGA 690 help 691 Supports loading an FPGA device from a bitstream buffer containing 692 a partial bitstream. 693 694config CMD_FPGA_LOADFS 695 bool "fpga loadfs - load bitstream from FAT filesystem (Xilinx only)" 696 depends on CMD_FPGA 697 help 698 Supports loading an FPGA device from a FAT filesystem. 699 700config CMD_FPGA_LOADMK 701 bool "fpga loadmk - load bitstream from image" 702 depends on CMD_FPGA 703 help 704 Supports loading an FPGA device from a image generated by mkimage. 705 706config CMD_FPGA_LOADP 707 bool "fpga loadp - load partial bitstream" 708 depends on CMD_FPGA 709 help 710 Supports loading an FPGA device from a bitstream buffer containing 711 a partial bitstream. 712 713config CMD_FPGAD 714 bool "fpgad - dump FPGA registers" 715 help 716 (legacy, needs conversion to driver model) 717 Provides a way to dump FPGA registers by calling the board-specific 718 fpga_get_reg() function.
