It also maintains a checksum 538 of the trace records (even if space is exhausted) so that the 539 sequence of I/O accesses can be verified. 540 541 When debugging drivers it is useful to see what I/O accesses were 542 done and in what order. 543 544 Even if the individual accesses are of little interest it can be 545 useful to verify that the access pattern is consistent each time 546 an operation is performed. In this case a checksum can be used to 547 characterise the operation of a driver. The checksum can be compared 548 across different runs of the operation to verify that the driver is 549 working properly. 550 551 In particular, when performing major refactoring of the driver, where 552 the access pattern should not change, the checksum provides assurance 553 that the refactoring work has not broken the driver. 554 555 This works by sneaking into the io.h heder for an architecture and 556 redirecting I/O accesses through iotrace's tracing mechanism. 557 558 For now no commands are provided to examine the trace buffer. The 559 format is fairly simple, so 'md' is a reasonable substitute. 560 561 Note: The checksum feature is only useful for I/O regions where the 562 contents do not change outside of software control. Where this is not 563 suitable you can fall back to manually comparing the addresses. It 564 might be useful to enhance tracing to only checksum the accesses and 565 not the data read/written. 566 567config CMD_LOADB 568 bool "loadb" 569 default y 570 help 571 Load a binary file over serial line. 572 573config CMD_LOADS 574 bool "loads" 575 default y 576 help 577 Load an S-Record file over serial line 578 579config CMD_FLASH 580 bool "flinfo, erase, protect" 581 default y 582 help 583 NOR flash support. 584 flinfo - print FLASH memory information 585 erase - FLASH memory 586 protect - enable or disable FLASH write protection 587 588config CMD_GPT 589 bool "GPT (GUID Partition Table) command" 590 select PARTITION_UUIDS 591 select EFI_PARTITION 592 help 593 Enable the 'gpt' command to ready and write GPT style partition 594 tables. 595 596config CMD_ARMFLASH 597 #depends on FLASH_CFI_DRIVER 598 bool "armflash" 599 help 600 ARM Ltd reference designs flash partition access 601 602config CMD_MMC 603 bool "mmc" 604 help 605 MMC memory mapped support. 606 607config CMD_NAND 608 bool "nand" 609 default y if NAND_SUNXI 610 help 611 NAND support. 612 613if CMD_NAND 614config CMD_NAND_TRIMFFS 615 bool "nand write.trimffs" 616 default y if ARCH_SUNXI 617 help 618 Allows one to skip empty pages when flashing something on a NAND. 619 620config CMD_NAND_LOCK_UNLOCK 621 bool "nand lock/unlock" 622 help 623 NAND locking support. 624 625config CMD_NAND_TORTURE 626 bool "nand torture" 627 help 628 NAND torture support. 629 630endif # CMD_NAND 631 632config CMD_PART 633 bool "part" 634 select PARTITION_UUIDS 635 help 636 Read and display information about the partition table on 637 various media. 638 639config CMD_SF 640 bool "sf" 641 help 642 SPI Flash support 643 644config CMD_SPI 645 bool "sspi" 646 help 647 SPI utility command. 648 649config CMD_I2C 650 bool "i2c" 651 help 652 I2C support. 653 654config CMD_USB 655 bool "usb" 656 help 657 USB support. 658 659config CMD_DFU 660 bool "dfu" 661 select USB_FUNCTION_DFU 662 help 663 Enables the command "dfu" which is used to have U-Boot create a DFU 664 class device via USB. 665 666config CMD_USB_MASS_STORAGE 667 bool "UMS usb mass storage" 668 help 669 USB mass storage support 670 671config CMD_FPGA 672 bool "fpga" 673 default y 674 help 675 FPGA support. 676 677config CMD_FPGA_LOADBP 678 bool "fpga loadbp - load partial bitstream (Xilinx only)" 679 depends on CMD_FPGA 680 help 681 Supports loading an FPGA device from a bitstream buffer containing 682 a partial bitstream. 683 684config CMD_FPGA_LOADFS 685 bool "fpga loadfs - load bitstream from FAT filesystem (Xilinx only)" 686 depends on CMD_FPGA 687 help 688 Supports loading an FPGA device from a FAT filesystem. 689 690config CMD_FPGA_LOADMK 691 bool "fpga loadmk - load bitstream from image" 692 depends on CMD_FPGA 693 help 694 Supports loading an FPGA device from a image generated by mkimage. 695 696config CMD_FPGA_LOADP 697 bool "fpga loadp - load partial bitstream" 698 depends on CMD_FPGA 699 help 700 Supports loading an FPGA device from a bitstream buffer containing 701 a partial bitstream. 702 703config CMD_FPGAD 704 bool "fpgad - dump FPGA registers" 705 help 706 (legacy, needs conversion to driver model) 707 Provides a way to dump FPGA registers by calling the board-specific 708 fpga_get_reg() function.
