USB: Use (get|put)_unaligned for accessing wMaxPacketSize

2011-12-16T20:37:17+00:00

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.

GCC4.6: Fix common/usb.c on xscale

2011-11-15T21:24:50+00:00

The problem was that the code, when the function was compiled with -Os, was
misgenerated. As in the function description, this is likely another
manifestation of the bug in GCC.

Revert "GCC4.6: Convert various empty macros to inline functions"

2011-10-04T19:19:19+00:00

This reverts commit 60ce53cf9f408d9ad721f8e7a87d6a564e6d5bac.

The commit causes build breakage for a number of boards. This results
from the fact that now the arguments of debug() actually get
referenced (even if there is hope that the compiler will optimize
away the debug() call).  The obvious fix to that probem (change the
code to always declare the referenced variables and data structures)
increases the code size, and was this rejected.  So it was decided to
revert this commit until a better solution is found.

Add USB host ethernet adapter support

2011-02-19T19:32:36+00:00

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
CONFIG_USB_HOST_ETHER can be defined in board config files to switch this
on.

The was originally written by NVIDIA and was cleaned up for release by the
Chromium authors.

USB: Change the necessary defines to get debug output

2011-02-05T12:54:51+00:00

While debugging some USB stuff, I've first missed that there are actually
two defines necessary to get usefull output. The one needed to get debug output
for the communication with HUBs was burried somewhere deep inside the code.

Change that so that a #define DEBUG is enough while still leaving the possibility
to reduce unwanted debug output.
