The Ethernet initialization functions are supposed to return the number of
devices initialized, so fix tsec_eth_init() so that they returns the number of
TSECs initialized, instead of just zero. This is safe because the return value
is currently ignored by all callers, but now they don't have to ignore it.
In general, if an function initializes only one device, then it should return
a negative number if there's an error. If it initializes more than one device,
then it should never return a negative number.

The DM9000 in/out helper functions were casting the register address when
it was accessing things directly (pre commit a45dde2293). But
when it was changed to using the in/out helpers, those casts were dropped
because those functions don't take pointers. Even more recently, those
functions were then changed to use the read/write helpers, but the casts
were not re-added. This is necessary because the read/write helpers do
take pointers. Otherwise we get a lot of warnings like:
dm9000x.c: In function 'dm9000_inblk_8bit':
dm9000x.c:172: warning: passing argument 1 of 'readb'
makes pointer from integer without a cast

This patch provides support for MPC8308RDB development board from
Freescale with a minimal set of features:
Dual UART is supported
NOR flash is supported
Both TSEC Ethernet controllers are supported
PCI Express initialization is supported
The following features are enabled in configuration but not fully tested:
I2C (used to get the board revision)
I2C-connected RTC
VSC7385 switch
There is one (hopefully) minor issue: on soft reset the board sometimes
resets twice. I've not managed to find the fix for this problem yet.
As a workaround instruction cache can be disabled.

Avoid banging on the trace MMRs when debugging is disabled, avoid calling
the funcs multiple times in a row, disable the trace buffer earlier in the
exception handler to avoid eating more user entries, and dump the buffer
before calling the kgdb hook. This way we maximize useful debugging info
up front rather than needing external tools (like gdb/serial/etc...).

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) {

Background Info:
Some PPC440/460 boards have caches enabled in the Boot/FLASH TLB (via
init.S) to speed up the boot process. In relocate_code (start.S) the
cache inhibit attribute for this TLB is set to disable cache. This is
needed for the CFI FLASH driver.
This patch now cleans this code up:
- CONFIG_SYS_TLB_FOR_BOOT_FLASH is defined to 0 (default TLB) if not
defined in the top of this file. This way, we can remove an ugly
#ifdef in this code.
- Replace complex "#if defined(CONFIG_440EP) || defined(CONFIG_GR)..."
statement with "#if defined(CONFIG_440)".
- Remove unnecessary cache invalidate calls resulting in faster bootup.
