55d5fd9a84 net: Access mapped physmem in net functions
Previously the net functions would access memory assuming physmem did
not need to be mapped.  In sandbox, that's not the case.

Now we map the physmem specified by the user in loadaddr to the buffer
that represents that space.

8e52533d10 net: tftpsrv: Get correct client MAC address
NetServerEther was not being cleared in the tftp server code, so the
destination MAC address would be whatever the last destination MAC
address was.

Scenario:
U-Boot:
	dhcp
	tftpsrv
Host:
	Send device WRQ
Device:
	Responds with ACK to dhcp server mac address with
	host ip address

By clearing NetServerEther, we force a lookup of the host MAC address
to go with the associated host IP.

bc46dfac2f net: tftp: fix type of block arg to store_block
The block argument for store_block can be -1 when the tftp sequence
number rolls over (i.e TftpBlock == 0), so the first argument to
store_block has to be of type 'int' instead of 'unsigned'.

In our environment (gcc 4.4.5 mips toolchain), this causes incorrect
'offset' to be generated for storing the block, and the tftp block
with number 0 will be written elsewhere, resulting in a bad block in
the downloaded file and a memory corruption.

ea45cb0adc net: Make sure IPaddr_t is 32 bits in size
When building u-boot as 64 bit application (e.g. sandbox) ulong might be
64 bits in size. This breaks network code as IPaddr_t is 64 bytes in
size then and an IPv4 address is 32 bits in size. This patch makes sure
that IPaddr_t is always 32 bits in size. Also some warnings introduced
by this patch are fixed.

c96f86eefc TFTP: allow for adjustable retransmission timout
So far, TFTP negotiated a fixed retransmission timeout of 5 seconds.
In some cases (busy networks, slow TFTP servers) this caused very
slow transfers. A new environment variable "tftptimeout" allows to
set this timeout. Lowering this value may make downloads succeed
faster in networks with high packet loss rates or with unreliable
TFTP servers.

4fccb818e7 Add Transfer Size Option to tftp
Optionally add RFC 2349 "Transfer Size Option", so we can minimize the
time spent sending data over the UART (now print a single line during a
tftp transfer).

 - If turned on (CONFIG_TFTP_TSIZE), U-Boot asks for the size of the file.
 - if receives the file size, a single line (50 chars) are printed.
     one hash mark == 2% of the file downloaded.
 - if it doesn't receive the file size (the server doesn't support RFC
     2349, prints standard hash marks (one mark for each UDP frame).

6a86bb6c25 net: Fix TftpStart() ip:filename bug
The TftpStart() function modifies the 'BootFile'
string when 'BootFile' contains both an IP address
and filename (eg 1.2.3.4:/path/file). This causes
subsequent calls to TftpStart to incorrectly parse
the TFTP filename and server IP address to use.
For example:

Speed: 100, half duplex

TFTP from server 10.52.0.62; our IP address is 10.52.253.79

          ^^^^^^^^^^^^^^^^^^^^^^^^^ CORRECT
