Now DT support is becoming common for all new SoC's. Hence it is better to have option for getting specific FDT from the remote server. This patch adds support for new label i.e. 'fdt'. This will allow to retrieve 'fdt blob' from the remote server. This patch take care for the following scenarios. The usage of fdt is optional. The 'fdt blob' can be retrieved from tftp or can be available locally or can be absent. If 'fdt_addr_r' environment variable is set and 'fdt' label is defined retrieve 'fdt blob' from tftp. 'fdt_addr_r' is then passed along bootm command. If 'fdt_addr' is set and 'fdt blob' is not retrieved from the tftp pass 'fdt_addr' to bootm command. In this case 'fdt blob' will be available at 'fdt_addr'. If 'fdt_addr' is not set and 'fdt blob' is not retrieve from tftp pass NULL to boot command. In this case 'fdt blob' is not required and absent. Signed-off-by: Chander Kashyap <chander.kashyap@linaro.org> Acked-by: Jason Hobbs <jason.hobbs@calxeda.com>
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
