It also maintains a checksum 520 of the trace records (even if space is exhausted) so that the 521 sequence of I/O accesses can be verified. 522 523 When debugging drivers it is useful to see what I/O accesses were 524 done and in what order. 525 526 Even if the individual accesses are of little interest it can be 527 useful to verify that the access pattern is consistent each time 528 an operation is performed. In this case a checksum can be used to 529 characterise the operation of a driver. The checksum can be compared 530 across different runs of the operation to verify that the driver is 531 working properly. 532 533 In particular, when performing major refactoring of the driver, where 534 the access pattern should not change, the checksum provides assurance 535 that the refactoring work has not broken the driver. 536 537 This works by sneaking into the io.h heder for an architecture and 538 redirecting I/O accesses through iotrace's tracing mechanism. 539 540 For now no commands are provided to examine the trace buffer. The 541 format is fairly simple, so 'md' is a reasonable substitute. 542 543 Note: The checksum feature is only useful for I/O regions where the 544 contents do not change outside of software control. Where this is not 545 suitable you can fall back to manually comparing the addresses. It 546 might be useful to enhance tracing to only checksum the accesses and 547 not the data read/written. 548 549config CMD_LOADB 550 bool "loadb" 551 default y 552 help 553 Load a binary file over serial line. 554 555config CMD_LOADS 556 bool "loads" 557 default y 558 help 559 Load an S-Record file over serial line 560 561config CMD_FLASH 562 bool "flinfo, erase, protect" 563 default y 564 help 565 NOR flash support. 566 flinfo - print FLASH memory information 567 erase - FLASH memory 568 protect - enable or disable FLASH write protection 569 570config CMD_GPT 571 bool "GPT (GUID Partition Table) command" 572 select PARTITION_UUIDS 573 select EFI_PARTITION 574 help 575 Enable the 'gpt' command to ready and write GPT style partition 576 tables. 577 578config CMD_ARMFLASH 579 #depends on FLASH_CFI_DRIVER 580 bool "armflash" 581 help 582 ARM Ltd reference designs flash partition access 583 584config CMD_MMC 585 bool "mmc" 586 help 587 MMC memory mapped support. 588 589config CMD_NAND 590 bool "nand" 591 default y if NAND_SUNXI 592 help 593 NAND support. 594 595if CMD_NAND 596config CMD_NAND_TRIMFFS 597 bool "nand write.trimffs" 598 default y if ARCH_SUNXI 599 help 600 Allows one to skip empty pages when flashing something on a NAND. 601 602config CMD_NAND_LOCK_UNLOCK 603 bool "nand lock/unlock" 604 help 605 NAND locking support. 606 607config CMD_NAND_TORTURE 608 bool "nand torture" 609 help 610 NAND torture support. 611 612endif # CMD_NAND 613 614config CMD_PART 615 bool "part" 616 select PARTITION_UUIDS 617 help 618 Read and display information about the partition table on 619 various media. 620 621config CMD_SF 622 bool "sf" 623 help 624 SPI Flash support 625 626config CMD_SPI 627 bool "sspi" 628 help 629 SPI utility command. 630 631config CMD_I2C 632 bool "i2c" 633 help 634 I2C support. 635 636config CMD_USB 637 bool "usb" 638 help 639 USB support. 640 641config CMD_DFU 642 bool "dfu" 643 select USB_FUNCTION_DFU 644 help 645 Enables the command "dfu" which is used to have U-Boot create a DFU 646 class device via USB. 647 648config CMD_USB_MASS_STORAGE 649 bool "UMS usb mass storage" 650 help 651 USB mass storage support 652 653config CMD_FPGA 654 bool "fpga" 655 default y 656 help 657 FPGA support. 658 659config CMD_FPGA_LOADBP 660 bool "fpga loadbp - load partial bitstream (Xilinx only)" 661 depends on CMD_FPGA 662 help 663 Supports loading an FPGA device from a bitstream buffer containing 664 a partial bitstream. 665 666config CMD_FPGA_LOADFS 667 bool "fpga loadfs - load bitstream from FAT filesystem (Xilinx only)" 668 depends on CMD_FPGA 669 help 670 Supports loading an FPGA device from a FAT filesystem. 671 672config CMD_FPGA_LOADMK 673 bool "fpga loadmk - load bitstream from image" 674 depends on CMD_FPGA 675 help 676 Supports loading an FPGA device from a image generated by mkimage. 677 678config CMD_FPGA_LOADP 679 bool "fpga loadp - load partial bitstream" 680 depends on CMD_FPGA 681 help 682 Supports loading an FPGA device from a bitstream buffer containing 683 a partial bitstream. 684 685config CMD_FPGAD 686 bool "fpgad - dump FPGA registers" 687 help 688 (legacy, needs conversion to driver model) 689 Provides a way to dump FPGA registers by calling the board-specific 690 fpga_get_reg() function.
