Algapally Santosh Sagar bd9ff681bd serial: zynqmp: Fetch baudrate from dtb and update 
The baudrate configured in .config is taken by default by serial. If
change of baudrate is required then the .config needs to changed and
u-boot recompilation is required or the u-boot environment needs to be
updated.

To avoid this, support is added to fetch the baudrate directly from the
device tree file and update.
The serial, prints the log with the configured baudrate in the dtb.
The commit c4df0f6f31 ("arm: mvebu: Espressobin: Set default value for
$fdtfile env variable") is taken as reference for changing the default
environment variable.

The default environment stores the default baudrate value, When default
baudrate and dtb baudrate are not same glitches are seen on the serial.
So, the environment also needs to be updated with the dtb baudrate to
avoid the glitches on the serial.

Also add test to cover this new function.

README.zfs 

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

	-- ZFS GRUB sources from Solaris GRUB-0.97
	-- GRUB Bazaar repository
