The output from "dm tree" or "dm uclass" is a bit annoying if the number of devices available on the system is huge. (This is especially true on sandbox when I debug some DM code.) With this patch, we can specify the uclass name or the device name that we are interested in in order to limit the output. For instance, => dm uclass usb uclass 121: usb 0 usb@1 @ 0bcff8b0, seq 1 uclass 124: usb => dm tree usb:usb@1 Class Index Probed Driver Name ----------------------------------------------------------- usb 0 [ ] usb_sandbox usb@1 usb_hub 0 [ ] usb_hub `-- hub usb_emul 0 [ ] usb_sandbox_hub `-- hub-emul usb_emul 1 [ ] usb_sandbox_flash |-- flash-stick@0 usb_emul 2 [ ] usb_sandbox_flash |-- flash-stick@1 usb_emul 3 [ ] usb_sandbox_flash |-- flash-stick@2 usb_emul 4 [ ] usb_sandbox_keyb `-- keyb@3 If you want forward-matching against a uclass or udevice name, you can specify "-e" option. => dm uclass -e usb uclass 15: usb_emul 0 hub-emul @ 0bcffb00, seq 0 1 flash-stick@0 @ 0bcffc30, seq 1 2 flash-stick@1 @ 0bcffdc0, seq 2 3 flash-stick@2 @ 0bcfff50, seq 3 4 keyb@3 @ 0bd000e0, seq 4 uclass 64: usb_mass_storage uclass 121: usb 0 usb@1 @ 0bcff8b0, seq 1 uclass 122: usb_dev_generic uclass 123: usb_hub 0 hub @ 0bcff9b0, seq 0 uclass 124: usb => dm tree -e usb Class Index Probed Driver Name ----------------------------------------------------------- usb 0 [ ] usb_sandbox usb@1 usb_hub 0 [ ] usb_hub `-- hub usb_emul 0 [ ] usb_sandbox_hub `-- hub-emul usb_emul 1 [ ] usb_sandbox_flash |-- flash-stick@0 usb_emul 2 [ ] usb_sandbox_flash |-- flash-stick@1 usb_emul 3 [ ] usb_sandbox_flash |-- flash-stick@2 usb_emul 4 [ ] usb_sandbox_keyb `-- keyb@3 Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Reviewed-by: Simon Glass <sjg@chromium.org>
This patch series adds support for ZFS listing and load to u-boot. To Enable zfs ls and load commands, modify the board specific config file with #define CONFIG_CMD_ZFS Steps to test: 1. After applying the patch, zfs specific commands can be seen in the boot loader prompt using UBOOT #help zfsload- load binary file from a ZFS file system zfsls - list files in a directory (default /) 2. To list the files in zfs pool, device or partition, execute zfsls <interface> <dev[:part]> [POOL/@/dir/file] For example: UBOOT #zfsls mmc 0:5 /rpool/@/usr/bin/ 3. To read and load a file from an ZFS formatted partition to RAM, execute zfsload <interface> <dev[:part]> [addr] [filename] [bytes] For example: UBOOT #zfsload mmc 2:2 0x30007fc0 /rpool/@/boot/uImage References : -- ZFS GRUB sources from Solaris GRUB-0.97 -- GRUB Bazaar repository Jorgen Lundman <lundman at lundman.net> 2012.
