The hush shell dynamically allocates (and re-allocates) memory for the
argument strings in the "char *argv[]" argument vector passed to
commands. Any code that modifies these pointers will cause serious
corruption of the malloc data structures and crash U-Boot, so make
sure the compiler can check that no such modifications are being done
by changing the code into "char * const argv[]".
This modification is the result of debugging a strange crash caused
after adding a new command, which used the following argument
processing code which has been working perfectly fine in all Unix
systems since version 6 - but not so in U-Boot:
int main (int argc, char **argv)
{
while (--argc > 0 && **++argv == '-') {
/* ====> */ while (*++*argv) {
switch (**argv) {
case 'd':
debug++;
break;
...
default:
usage ();
}
}
}
...
}
The line marked "====>" will corrupt the malloc data structures and
usually cause U-Boot to crash when the next command gets executed by
the shell. With the modification, the compiler will prevent this with
an
error: increment of read-only location '*argv'
N.B.: The code above can be trivially rewritten like this:
while (--argc > 0 && **++argv == '-') {
char *arg = *argv;
while (*++arg) {
switch (*arg) {
...

linking eeprom with libgeneric.a is not really needed and causes following
error:
../../lib_generic/libgeneric.a(string.o): In function `strcmp':
/home/ladis/src/u-boot-ti/lib_generic/string.c:152: multiple definition of `strcmp'
../../examples/standalone/libstubs.a(stubs.o):include/_exports.h:24: first defined here
make[1]: *** [eeprom.srec] Error 1
Fix undefined reference to memset generated by some versions of gcc
to zero out initialized structure on the stack:
eeprom.o: In function `eeprom':
board/voiceblue/eeprom.c:152: undefined reference to `memset'

All in-tree boards that use this controller have CONFIG_NET_MULTI
added
Also:
- changed CONFIG_DRIVER_SMC91111 to CONFIG_SMC91111
- cleaned up line lengths
- modified all boards that override weak function in this driver
- modified all eeprom standalone apps to work with new driver
- updated blackfin standalone EEPROM app after testing
