The UFS tool provides utilities for querying, displaying, and modifying UFS device configuration and descriptor information.
Features: - Query and display Device, Geometry, Unit, Configuration, and Power Descriptors - Display LUN configuration and calculated capacities - Modify LUN, Configuration, and Device Descriptor fields - Configure WriteBooster-related parameters - Query common UFS runtime flags - Commit configuration changes or clear all LUN configurations - Decode and format descriptor contents for easier debugging Signed-off-by: Raz Ben Yehuda <[email protected]> --- cmd/ufs.c | 93 ++++++++++++++++++++++++++++++++++++++++++++++++++++--- 1 file changed, 89 insertions(+), 4 deletions(-) diff --git a/cmd/ufs.c b/cmd/ufs.c index 790dab50f18..c8bafcd5e1d 100644 --- a/cmd/ufs.c +++ b/cmd/ufs.c @@ -24,15 +24,100 @@ static int do_ufs(struct cmd_tbl *cmdtp, int flag, int argc, char *const argv[]) } else { ufs_probe(); } - return CMD_RET_SUCCESS; } - } - return CMD_RET_USAGE; +#if IS_ENABLED(CONFIG_UFS_TOOL) + if (!strcmp(argv[1], "query")) { + int lun = -1; + int idn = -1; + + if (argc <= 3) { + printf("usage: lun idn"); + return CMD_RET_FAILURE; + } + + lun = dectoul(argv[2], NULL); + idn = dectoul(argv[3], NULL); + + return ufs_tool_query(lun, idn); + } + + if (!strcmp(argv[1], "set_lun")) { + int lun; + u32 val; + + if (argc <= 4) { + ufs_tool_help(); + return CMD_RET_FAILURE; + } + lun = dectoul(argv[2], NULL); + val = dectoul(argv[4], NULL); + return ufs_tool_set_lun(lun, argv[3], val); + } + + if (!strcmp(argv[1], "set_dev_desc")) { + const char *name; + u32 val; + + if (argc <= 3) { + ufs_tool_help(); + return CMD_RET_FAILURE; + } + name = argv[2]; + val = dectoul(argv[3], NULL); + return ufs_tool_set_device_desc(name, val); + } + + if (!strcmp(argv[1], "set_cfg_desc")) { + const char *name; + u32 val; + + if (argc <= 3) { + ufs_tool_help(); + return CMD_RET_FAILURE; + } + name = argv[2]; + val = dectoul(argv[3], NULL); + return ufs_tool_set_config_desc(name, val); + } + + if (!strcmp(argv[1], "getflag")) { + if (argc == 2) { + printf("usage: getflag [flag name]"); + ufs_tool_help(); + return CMD_RET_FAILURE; + } + return ufs_tool_query_flag(argv[2]); + } + + if (!strcmp(argv[1], "commit")) + return ufs_tool_commit(); + + if (!strcmp(argv[1], "clearall")) + return ufs_tool_clearall(); + + if (!strcmp(argv[1], "luns")) { + ufs_tool_print_luns(); + return 0; + } + } + ufs_tool_help(); +#endif + return CMD_RET_FAILURE; } -U_BOOT_CMD(ufs, 3, 1, do_ufs, +U_BOOT_CMD(ufs, 5, 1, do_ufs, "UFS sub-system", "init [dev] - init UFS subsystem\n" +#if IS_ENABLED(CONFIG_UFS_TOOL) + "query [LUN] [IDN]\n" + "set_lun [LUN] [parm name] [value]\n" + "set_cfg_des [parm name] [value]\n" + "set_dev_desc [parm name] [value]\n" + "luns - prints luns\n" + "clearall - zero out configuration descriptor\n" + "getflag [flag name]\n" + "commit - writes luns configuration\n" +#endif ); -- 2.43.0
