If the user sets bootm_low and does not set bootm_size, u-boot will
report the memory node in the flat device tree incorrectly. Instead
of reporting the remaining size of memory, it will report the total
available memory which is incorrect.

Specifically this fixes the situation when booting a relocatable
kernel and the memory is reported as an offset and size in the
device tree, and the size needs to be adjusted accordingly.

Some commands (like 'mii') use this name to select devices, but they
break when those names contain spaces. So drop the space from
Ethernet driver names (cf. commit 1384f3bb).

While running from flash, i. e. before relocation, we have only a
limited C runtime environment without writable data segment. In this
phase, some configurations (for example with environment in EEPROM)
must not use the normal getenv(), but a special function.  This
function had been called getenv_r(), with the idea that the "_r"
suffix would mean the same as in the _r_eentrant versions of some of
the C library functions (for example getdate vs. getdate_r, getgrent
vs. getgrent_r, etc.).

Unfortunately this was a misleading name, as in U-Boot the "_r"
generally means "running from RAM", i. e. _after_ relocation.

To avoid confusion, rename into getenv_f() [as "running from flash"]

	'lzmaBuffToBuffDecompress' from incompatible pointer type

For 32 bit systems, this change shouldn't make a difference to code size
since sizeof(size_t) and sizeof(unsigned int) are equal.  But it does fix
the warning.

Serial devices currently have to manually stuff \r after every \n found,
but this is a bit more difficult with the jtag console since we process
everything in chunks of 4 bit.  So we have to scan & stuff the whole
string rather than what most serial drivers do which is output on a byte
per byte basis.

While we're in here, add some useful debug points.  We need custom debug
statements because we need the output to only go to the serial port.  If
we used the standard debug helpers, the output would also go to the stdout
(which would be the jtag console) and make it hard to figure out what is
going where exactly.

If the other side isn't listening, we should reset the state to ignore
the whole message and not just the part we missed.  This makes it easier
to connect at any time to the jtag console without worrying about the two
sides getting out of sync and thus sending garbage back and forth.

On FAT32, instead of fetching the cluster numbers from the FAT, the
code assumed (incorrectly) that the clusters for the root directory
were allocated contiguously. In the result, only the first cluster
could be accessed. At the typical cluster size of 8 sectors this
caused all accesses to files after the first 128 entries to fail -
"fatls" would terminate after 128 files (usually displaying a bogus
file name, occasionally even crashing the system), and "fatload"
would fail to find any files that were not in the first directory
cluster.
