It also maintains a checksum 747 of the trace records (even if space is exhausted) so that the 748 sequence of I/O accesses can be verified. 749 750 When debugging drivers it is useful to see what I/O accesses were 751 done and in what order. 752 753 Even if the individual accesses are of little interest it can be 754 useful to verify that the access pattern is consistent each time 755 an operation is performed. In this case a checksum can be used to 756 characterise the operation of a driver. The checksum can be compared 757 across different runs of the operation to verify that the driver is 758 working properly. 759 760 In particular, when performing major refactoring of the driver, where 761 the access pattern should not change, the checksum provides assurance 762 that the refactoring work has not broken the driver. 763 764 This works by sneaking into the io.h heder for an architecture and 765 redirecting I/O accesses through iotrace's tracing mechanism. 766 767 For now no commands are provided to examine the trace buffer. The 768 format is fairly simple, so 'md' is a reasonable substitute. 769 770 Note: The checksum feature is only useful for I/O regions where the 771 contents do not change outside of software control. Where this is not 772 suitable you can fall back to manually comparing the addresses. It 773 might be useful to enhance tracing to only checksum the accesses and 774 not the data read/written. 775 776config CMD_I2C 777 bool "i2c" 778 help 779 I2C support. 780 781config CMD_LOADB 782 bool "loadb" 783 default n if ARCH_SUNXI 784 default y 785 help 786 Load a binary file over serial line. 787 788config CMD_LOADS 789 bool "loads" 790 default n if ARCH_SUNXI 791 default y 792 help 793 Load an S-Record file over serial line 794 795config CMD_MMC 796 bool "mmc" 797 help 798 MMC memory mapped support. 799 800config CMD_NAND 801 bool "nand" 802 default y if NAND_SUNXI 803 help 804 NAND support. 805 806if CMD_NAND 807config CMD_NAND_TRIMFFS 808 bool "nand write.trimffs" 809 default y if ARCH_SUNXI 810 help 811 Allows one to skip empty pages when flashing something on a NAND. 812 813config CMD_NAND_LOCK_UNLOCK 814 bool "nand lock/unlock" 815 help 816 NAND locking support. 817 818config CMD_NAND_TORTURE 819 bool "nand torture" 820 help 821 NAND torture support. 822 823endif # CMD_NAND 824 825config CMD_NVME 826 bool "nvme" 827 depends on NVME 828 default y if NVME 829 help 830 NVM Express device support 831 832config CMD_MMC_SPI 833 bool "mmc_spi - Set up MMC SPI device" 834 help 835 Provides a way to set up an MMC (Multimedia Card) SPI (Serial 836 Peripheral Interface) device.

Two sub-commands are provided: 1522 1523 zfsls - list files in a directory 1524 zfsload - load a file 1525 1526 See doc/README.zfs for more details. 1527 1528endmenu 1529 1530menu "Debug commands" 1531 1532config CMD_BEDBUG 1533 bool "bedbug" 1534 help 1535 The bedbug (emBEDded deBUGger) command provides debugging features 1536 for some PowerPC processors. For details please see the 1537 docuemntation in doc/README.beddbug 1538 1539config CMD_DIAG 1540 bool "diag - Board diagnostics" 1541 help 1542 This command provides access to board diagnostic tests. These are 1543 called Power-on Self Tests (POST). The command allows listing of 1544 available tests and running either all the tests, or specific tests 1545 identified by name. 1546 1547config CMD_IRQ 1548 bool "irq - Show information about interrupts" 1549 depends on !ARM && !MIPS && !SH 1550 help 1551 This enables two commands: 1552 1553 interrupts - enable or disable interrupts 1554 irqinfo - print device-specific interrupt information 1555 1556config CMD_KGDB 1557 bool "kgdb - Allow debugging of U-Boot with gdb" 1558 help 1559 This enables a 'kgdb' command which allows gdb to connect to U-Boot 1560 over a serial link for debugging purposes. This allows 1561 single-stepping, inspecting variables, etc. This is supported only 1562 on PowerPC at present. 1563 1564config CMD_LOG 1565 bool "log - Generation, control and access to logging" 1566 help 1567 This provides access to logging features. It allows the output of 1568 log data to be controlled to a limited extent (setting up the default 1569 maximum log level for emitting of records). It also provides access 1570 to a command used for testing the log system. 1571 1572config CMD_TRACE 1573 bool "trace - Support tracing of function calls and timing" 1574 help 1575 Enables a command to control using of function tracing within 1576 U-Boot. This allows recording of call traces including timing 1577 information. The command can write data to memory for exporting 1578 for analsys (e.g. using bootchart).
