34255b92e6 tools: env: Add support for direct read/write UBI volumes
Up to now we were able to read/write environment data from/to UBI
volumes only indirectly by gluebi driver. This driver creates NAND MTD
on top of UBI volumes, which is quite a workaroung for this use case.

Add support for direct read/write UBI volumes in order to not use
obsolete gluebi driver.

f4742ca0fb tools/env: allow negative offsets
A negative value for the offset is treated as a backwards offset for
from the end of the device/partition for block devices. This aligns
the behavior of the config file with the syntax of CONFIG_ENV_OFFSET
where the functionality has been introduced with
commit 5c088ee841 ("env_mmc: allow negative CONFIG_ENV_OFFSET").

de19eddf6c add example for file on VFAT filesystem usage
For example on a raspberry pi the u-boot environment can be
saved in a file on the first VFAT partition.
This example illustrates how to use it with fw_printenv/fw_setenv.

23869bf80b fw_env: calculate default number of env sectors
The assumed number of environment sectors (always 1) leads to an
incorrect top_of_range calculation in fw.env.c when a flash device has
an erase block size smaller than the environment data size (number of
environment sectors > 1).

This change updates the default number of environment sectors to at
least cover the size of the environment.

Also corrected a false statement about the number of sectors column in
fw_env.config.

9eeaa8e66c Add support for dataflash to U-boot environment settings tool.
* The sector size for SPI-dataflash (like AT45 flashes) are not always
  a power-of-2. So, the sector calculations are rewritten such that it
  works for either power-of-2 as any size sectors.
* Make the flash sector size optional in case it is the same value as
  the environment size.

d0fb80c302 * Restrict baudrate settings on LWMON to higher speeds
when watchdog is on

* Update baudrate in bd_info when it gets changed

* Add watchdog trigger points while waiting for serial port
  (so far only 8xx -- needed on LWMON with 100ms watchdog)

* Improve command line tool to access the U-Boot's environment
  (figuration of the utility, using a config file)
