It also maintains a checksum 509 of the trace records (even if space is exhausted) so that the 510 sequence of I/O accesses can be verified. 511 512 When debugging drivers it is useful to see what I/O accesses were 513 done and in what order. 514 515 Even if the individual accesses are of little interest it can be 516 useful to verify that the access pattern is consistent each time 517 an operation is performed. In this case a checksum can be used to 518 characterise the operation of a driver. The checksum can be compared 519 across different runs of the operation to verify that the driver is 520 working properly. 521 522 In particular, when performing major refactoring of the driver, where 523 the access pattern should not change, the checksum provides assurance 524 that the refactoring work has not broken the driver. 525 526 This works by sneaking into the io.h heder for an architecture and 527 redirecting I/O accesses through iotrace's tracing mechanism. 528 529 For now no commands are provided to examine the trace buffer. The 530 format is fairly simple, so 'md' is a reasonable substitute. 531 532 Note: The checksum feature is only useful for I/O regions where the 533 contents do not change outside of software control. Where this is not 534 suitable you can fall back to manually comparing the addresses. It 535 might be useful to enhance tracing to only checksum the accesses and 536 not the data read/written. 537 538config CMD_LOADB 539 bool "loadb" 540 default y 541 help 542 Load a binary file over serial line. 543 544config CMD_LOADS 545 bool "loads" 546 default y 547 help 548 Load an S-Record file over serial line 549 550config CMD_FLASH 551 bool "flinfo, erase, protect" 552 default y 553 help 554 NOR flash support. 555 flinfo - print FLASH memory information 556 erase - FLASH memory 557 protect - enable or disable FLASH write protection 558 559config CMD_GPT 560 bool "GPT (GUID Partition Table) command" 561 select PARTITION_UUIDS 562 select EFI_PARTITION 563 help 564 Enable the 'gpt' command to ready and write GPT style partition 565 tables. 566 567config CMD_ARMFLASH 568 #depends on FLASH_CFI_DRIVER 569 bool "armflash" 570 help 571 ARM Ltd reference designs flash partition access 572 573config CMD_MMC 574 bool "mmc" 575 help 576 MMC memory mapped support. 577 578config CMD_NAND 579 bool "nand" 580 default y if NAND_SUNXI 581 help 582 NAND support. 583 584if CMD_NAND 585config CMD_NAND_TRIMFFS 586 bool "nand write.trimffs" 587 default y if ARCH_SUNXI 588 help 589 Allows one to skip empty pages when flashing something on a NAND. 590 591config CMD_NAND_LOCK_UNLOCK 592 bool "nand lock/unlock" 593 help 594 NAND locking support. 595 596config CMD_NAND_TORTURE 597 bool "nand torture" 598 help 599 NAND torture support. 600 601endif # CMD_NAND 602 603config CMD_PART 604 bool "part" 605 select PARTITION_UUIDS 606 help 607 Read and display information about the partition table on 608 various media. 609 610config CMD_SF 611 bool "sf" 612 help 613 SPI Flash support 614 615config CMD_SPI 616 bool "sspi" 617 help 618 SPI utility command. 619 620config CMD_I2C 621 bool "i2c" 622 help 623 I2C support. 624 625config CMD_USB 626 bool "usb" 627 help 628 USB support. 629 630config CMD_DFU 631 bool "dfu" 632 select USB_FUNCTION_DFU 633 help 634 Enables the command "dfu" which is used to have U-Boot create a DFU 635 class device via USB. 636 637config CMD_USB_MASS_STORAGE 638 bool "UMS usb mass storage" 639 help 640 USB mass storage support 641 642config CMD_FPGA 643 bool "fpga" 644 default y 645 help 646 FPGA support. 647 648config CMD_FPGA_LOADBP 649 bool "fpga loadbp - load partial bitstream (Xilinx only)" 650 depends on CMD_FPGA 651 help 652 Supports loading an FPGA device from a bitstream buffer containing 653 a partial bitstream. 654 655config CMD_FPGA_LOADFS 656 bool "fpga loadfs - load bitstream from FAT filesystem (Xilinx only)" 657 depends on CMD_FPGA 658 help 659 Supports loading an FPGA device from a FAT filesystem. 660 661config CMD_FPGA_LOADMK 662 bool "fpga loadmk - load bitstream from image" 663 depends on CMD_FPGA 664 help 665 Supports loading an FPGA device from a image generated by mkimage. 666 667config CMD_FPGA_LOADP 668 bool "fpga loadp - load partial bitstream" 669 depends on CMD_FPGA 670 help 671 Supports loading an FPGA device from a bitstream buffer containing 672 a partial bitstream. 673 674config CMD_FPGAD 675 bool "fpgad - dump FPGA registers" 676 help 677 (legacy, needs conversion to driver model) 678 Provides a way to dump FPGA registers by calling the board-specific 679 fpga_get_reg() function.
