Remove sys/boot/arm/at91 and ixp425

Browse Source 
Remove at91 bootloader. It only worked on AT91RM9200, and only
specific boards that were all EOLd 10 years ago.

Remove ixp425. It doesn't build anymore and is for boards that were
EOLd 8 years ago.

This is a bootstrap bootloader. It is intended to be used when the
AT91RM9200 is running xmodem over DBGU. It will download the next stage
of the booting process (or the recovery program) and jump to it. It loads
the program at a 1MB offset into SDRAM. Programs are expected to be
smaller than this and copy themselves to the right location.

$FreeBSD$
This image is intended to be programmed into boot EEPROM. The image is nearly
0x4000 so it will not fit in KB9200's 0x2000. It is intended for KB9201 or
later. Alternatively, the KB9200 can be upgraded with larger EEPROM.
It performs basic functions prior to executing an image at a
specified address. The pre-boot functions can be modified and saved back into
EEPROM.
The MAC address is set with 0.0.0.0.0.0 by default. This is an invalid address
and must be changed to a valid value in order to use the ethernet interface.
Memory usage:
EEPROM = 0x4000
SDRAM =
run stack = 0x21800000
variables = 0x21200000
ethernet = 0x21000000 (buffers and descriptors)
Functions supported:
c - copy
d - display auto command table (in RAM)
e - execute image
? - help
ip - set local ip
m - set mac
server_ip - set server ip
s - set auto command entry
t - create linux boot tag list
tftp - download image via tftp
w - update auto command table
x - download image via xmodem

$FreeBSD$
This image is intended to be programmed into boot EEPROM. The image is nearly
0x4000 so it will not fit in KB9200's 0x2000. It is intended for KB9201 or
later. Alternatively, the KB9200 can be upgraded with larger EEPROM.
It performs basic functions prior to executing an image at a
specified address. The pre-boot functions can be modified and saved back into
EEPROM.
The MAC address is set with 0.0.0.0.0.0 by default. This is an invalid address
and must be changed to a valid value in order to use the ethernet interface.
Memory usage:
EEPROM = 0x4000
SDRAM =
run stack = 0x21800000
variables = 0x21200000
ethernet = 0x21000000 (buffers and descriptors)
Functions supported:
c - copy
d - display auto command table (in RAM)
e - execute image
? - help
ip - set local ip
m - set mac
server_ip - set server ip
s - set auto command entry
t - create linux boot tag list
tftp - download image via tftp
w - update auto command table
x - download image via xmodem
