This avoids cache-alignment warnings shown in console
when a usb command is entered.
Whenever X bytes of unaligned buffer is invalidated, arm core
invalidates X + Y bytes as per the cache line size and throws
these warnings.

This inserts bootstage calls into tftp, usb start and bootm. We

Change all files in common/ to use CMD_RET_USAGE instead of calling
cmd_usage() directly. I'm not completely sure about this patch since
the code since impact is small (100 byte or so on ARM) and it might
need splitting into smaller patches. But for now here it is.

In 9792987721c7980453fe6447c3fa6593b44f8458 Stefan describes a usecase
where the previous behavior of leaving wMaxPacketSize be unaligned
caused fatal problems. The initial fix for this problem was incomplete
however as it showed another cases of non-aligned access that previously
worked implicitly. This switches to making sure that all access of
wMaxPacketSize are done via (get|put)_unaligned.
In order to maintain a level of readability to the code in some cases
we now use a variable for the value of wMaxPacketSize and in others, a
macro.

Rather than having a bunch of random commands handle autostart behavior,
unify the logic in a single place. This also fixes building of these

This adds support for using USB Ethernet dongles in host mode. This is just
the framework - drivers will come later. A new config option called

Lots of code use this construct:
cmd_usage(cmdtp);
return 1;
Change cmd_usage() let it return 1 - then we can replace all these
ocurrances by
return cmd_usage(cmdtp);
This fixes a few places with incorrect return code handling, too.

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) {
...

Here's another USB storage patch. Currently U-Boot handles storage
devices #0 - #4 as valid devices, even if there is none connected. This
patch fixes usb_stor_get_dev() to check detected device count instead
of MAX-define.
This is very important for ill behaving devices. usb_dev_desc[] can be
partially initialized if device probe fails.
After fixing get_dev() it was easy to fix "usb part" etc commands.
Previously it outputed "Unknown partition table" five times, now it's
"no USB devices available".

It will be useful for filesystem write support to usb device from

sectors on a partition for usb write operation.]

The header files usb.h and usbdescriptors.h have the same nameed
structure definitions for
usb_config_descriptor
usb_interface_descriptor
usb_endpoint_descriptor
usb_device_descriptor
usb_string_descriptor
These are out right duplicates in usb.h
usb_device_descriptor
usb_string_descriptor
This one has extra unused elements
usb_endpoint_descriptor
unsigned char bRefresh
unsigned char bSynchAddress;
These in usb.h have extra elements at the end of the usb 2.0
specified descriptor and are used.
usb_config_descriptor
usb_interface_descriptor
The change is to consolidate the definition of the descriptors
to usbdescriptors.h. The dublicates in usb.h are removed.
The extra element structure will have their name shorted by
removing the '_descriptor' suffix.
So
usb_config_descriptor -> usb_config
usb_interface_descriptor -> usb_interface
For these, the common descriptor elements are accessed now
by an element 'desc'.
As an example
- if (iface->bInterfaceClass != USB_CLASS_HUB)
+ if (iface->desc.bInterfaceClass != USB_CLASS_HUB)
This has been compile tested on MAKEALL arm, ppc and mips.

Many of the help messages were not really helpful; for example, many
commands that take no arguments would not print a correct synopsis
line, but "No additional help available." which is not exactly wrong,
but not helpful either.
Commit ``Make "usage" messages more helpful.'' changed this
partially. But it also became clear that lots of "Usage" and "Help"
messages (fields "usage" and "help" in struct cmd_tbl_s respective)
were actually redundant.
This patch cleans this up - for example:
Before:
=> help dtt
dtt - Digital Thermometer and Thermostat
Usage:
dtt - Read temperature from digital thermometer and thermostat.
After:
=> help dtt
dtt - Read temperature from Digital Thermometer and Thermostat
Usage:
dtt

This patch adds framework for dual format images. Format detection is added
and the bootm controll flow is updated to include cases for new FIT format
uImages.
When the legacy (image_header based) format is detected appropriate
legacy specific handling is invoked. For the new (FIT based) format uImages
dual boot framework has a minial support, that will only print out a
corresponding debug messages. Implementation of the FIT specific handling will
be added in following patches.

A new, Windows compatible init sequence was also backported from Linux 2.6,
but disabled with #undef NEW_INIT_SEQ as it wouldn't change the behaviour

devices. For recerence, see file common/usb.c, function usb_new_device(),
section #ifdef NEW_INIT_SEQ.
