Make sure the 'exit' command as well as 'exit $val' command exits
from environment scripts immediately and propagates return value
out of those scripts fully. That means the following behavior is
expected:
"
=> setenv foo 'echo bar ; exit 1' ; run foo ; echo $?
bar
1
=> setenv foo 'echo bar ; exit 0' ; run foo ; echo $?
bar
0
=> setenv foo 'echo bar ; exit -2' ; run foo ; echo $?
bar
0
"
As well as the followin behavior:
"
=> setenv foo 'echo bar ; exit 3 ; echo fail'; run foo; echo $?
bar
3
=> setenv foo 'echo bar ; exit 1 ; echo fail'; run foo; echo $?
bar
1
=> setenv foo 'echo bar ; exit 0 ; echo fail'; run foo; echo $?
bar
0
=> setenv foo 'echo bar ; exit -1 ; echo fail'; run foo; echo $?
bar
0
=> setenv foo 'echo bar ; exit -2 ; echo fail'; run foo; echo $?
bar
0
=> setenv foo 'echo bar ; exit ; echo fail'; run foo; echo $?
bar
0
"

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
