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.

fw_env: correct writes to devices with small erase blocks

Some NOR flash devices have a small erase block size.  For example, the
Micron N25Q512 can erase in 4K blocks.  These devices expose a bug in
fw_env.c where flash_write_buf() incorrectly calculates bytes written
and attempts to write past the environment sectors.  Luckily, a range
check prevents any real damage, but this does cause fw_setenv to fail
with an error.

This change corrects the write length calculation.

The bug was introduced with commit 56086921 from 2008 and only affects
configurations where the erase block size is smaller than the total
environment data size.

usb: net: introduce support for Moschip USB ethernet

introduce an 'mcs7830' driver for Moschip MCS7830 based (7730/7830/7832)
USB 2.0 Ethernet Devices

see "MCS7830 -- USB 2.0 to 10/100M Fast Ethernet Controller" at
http://www.asix.com.tw/products.php?op=pItemdetail&PItemID=109;74;109

the driver was implemented based on the U-Boot Asix driver with
additional information gathered from the Moschip Linux driver,
development was done on "Delock 61147" and "Logilink UA0025C" dongles

- suggest to *not* put individual IP configuration parameters into the

  them from network
