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_ARMFLASH 599 #depends on FLASH_CFI_DRIVER 600 bool "armflash" 601 help 602 ARM Ltd reference designs flash partition access 603 604config CMD_MMC 605 bool "mmc" 606 help 607 MMC memory mapped support. 608 609config CMD_NAND 610 bool "nand" 611 default y if NAND_SUNXI 612 help 613 NAND support. 614 615if CMD_NAND 616config CMD_NAND_TRIMFFS 617 bool "nand write.trimffs" 618 default y if ARCH_SUNXI 619 help 620 Allows one to skip empty pages when flashing something on a NAND. 621 622config CMD_NAND_LOCK_UNLOCK 623 bool "nand lock/unlock" 624 help 625 NAND locking support. 626 627config CMD_NAND_TORTURE 628 bool "nand torture" 629 help 630 NAND torture support. 631 632endif # CMD_NAND 633 634config CMD_PART 635 bool "part" 636 select PARTITION_UUIDS 637 help 638 Read and display information about the partition table on 639 various media. 640 641config CMD_SF 642 bool "sf" 643 help 644 SPI Flash support 645 646config CMD_SPI 647 bool "sspi" 648 help 649 SPI utility command. 650 651config CMD_I2C 652 bool "i2c" 653 help 654 I2C support. 655 656config CMD_USB 657 bool "usb" 658 help 659 USB support. 660 661config CMD_DFU 662 bool "dfu" 663 select USB_FUNCTION_DFU 664 help 665 Enables the command "dfu" which is used to have U-Boot create a DFU 666 class device via USB. 667 668config CMD_USB_MASS_STORAGE 669 bool "UMS usb mass storage" 670 help 671 USB mass storage support 672 673config CMD_FPGA 674 bool "fpga" 675 default y 676 help 677 FPGA support. 678 679config CMD_FPGA_LOADBP 680 bool "fpga loadbp - load partial bitstream (Xilinx only)" 681 depends on CMD_FPGA 682 help 683 Supports loading an FPGA device from a bitstream buffer containing 684 a partial bitstream. 685 686config CMD_FPGA_LOADFS 687 bool "fpga loadfs - load bitstream from FAT filesystem (Xilinx only)" 688 depends on CMD_FPGA 689 help 690 Supports loading an FPGA device from a FAT filesystem. 691 692config CMD_FPGA_LOADMK 693 bool "fpga loadmk - load bitstream from image" 694 depends on CMD_FPGA 695 help 696 Supports loading an FPGA device from a image generated by mkimage. 697 698config CMD_FPGA_LOADP 699 bool "fpga loadp - load partial bitstream" 700 depends on CMD_FPGA 701 help 702 Supports loading an FPGA device from a bitstream buffer containing 703 a partial bitstream. 704 705config CMD_FPGAD 706 bool "fpgad - dump FPGA registers" 707 help 708 (legacy, needs conversion to driver model) 709 Provides a way to dump FPGA registers by calling the board-specific 710 fpga_get_reg() function.
