Heinrich Schuchardt d094a0734c log: allow for message continuation
Some drivers use macro pr_cont() for continuing a message sent via printk.
Hence if we want to convert printk messaging to using the logging system,
we must support continuation of log messages too.

As pr_cont() does not provide a message level we need a means of
remembering the last log level.

With the patch a pseudo log level LOGL_CONT as well as a pseudo log
category LOGC_CONT are introduced. Using these results in the application
of the same log level and category as in the previous log message.

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
