71ec92b67c vsprintf: Move function documentation into header file
Now that this is not in common.h, perhaps it is acceptable to move this
documentation into the header file.

046a37bd53 Add safe vsnprintf and snprintf library functions
From: Sonny Rao <sonnyrao@chromium.org>

These functions are useful in U-Boot because they allow a graceful failure
rather than an unpredictable stack overflow when printf() buffers are
exceeded.

Mostly copied from the Linux kernel. I copied vscnprintf and
scnprintf so we can change printf and vprintf to use the safe
implementation but still return the correct values.

(Simon Glass <sjg@chromium.org> modified this commit a little)

a7b3918533 tools/setlocalversion: Update from the Linux Kernel
Several bugfixes have occurred upstream since this script was imported
into U-Boot.  In particular, the script currently in U-Boot does not
describe commit f8bbb4dad0 correctly,
resulting in a version of "2011.09" instead of "2011.09-01460-gf8bbb4d".

With that commit checked out, the command "git name-rev --tags HEAD"
gives this result:
  HEAD tags/v2011.12-rc1~30^2

Then the "changes" regex does not match because of the trailing '^2':
  grep -E '^HEAD[[:space:]]+(.*~[0-9]*|undefined)$'

The new version of tools/setlocalversion in the kernel correctly handles
those situations by using different plumbing commands.

The version from the kernel is not directly usable as it does not append
the full GIT version that U-Boot expects unless the right config options
are set (CONFIG_LOCALVERSION_AUTO=y).  Other than a few minor changes
for Kconfig, the imported version is very similar to Linux v3.2-rc4.

b2fb47f187 USB: Use (get|put)_unaligned for accessing wMaxPacketSize
In 9792987721 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.

In the current u-boot code, the value of these fields are the reserved
value (0b100), through the signal integrity measurement on freescale's
board with these reserved setting, the signal eye is out of the recommended

According to the errata for MPC8379E, we should make a change to the

3b2001105f powerpc/bootm: Flush ramdisk and device tree image when booting on MP
We already flush the kernel image after we've loaded it to ensure
visiblity to the other cores.  We need to do the same thing for the
ramdisk and device tree images.  In AMP boot scenarios we might not be
HW cache coherent with the secondary core that we are loading and
setting the ramdisk and device tree up for.  Thus we need to ensure
we've flushed the regions of memory utilized by ramdisk and device tree
so the loadding and any modifications (from decompression or fdt updates)
are made visible to the secondary cores.

Switch to extension board detection using pci_find_device()
instead of detecting by i2c access to EEPROM device on
extension board.

This is a cleaner detection method since EEPROM addresses
can be different on different board revisions. This also
avoids "i2c_read: failed to address chip" error messages
in the boot log on boards without extension board which
may confuse users.

9792987721 usb: align usb_endpoint_descriptor to 16-bit boundary
The usb_endpoint_descriptor struct is 7 bytes large and is
defined as an array (ep_desc[USB_MAXENDPOINTS])
in the usb_interface struct in include/usb.h

This fact will result in that every odd index in that
array will start at an uneven address, this in
turn makes accesses to u16 wMaxPacketSize unaligned.
Such accesses are illegal on the OpenRISC architecture
(as well as other architectures) and will render a bus error.

Setting the aligned(2) attribute on usb_endpoint_descriptor
will force wMaxPacketSize to a 16-bit boundary.
