Clean a mixup between u32 and int as a return type
for functions returning error values.
Use int as it is native (and widely used) return type.

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
spec for non-transition amplitude at 500mV nominal.
According to the errata for MPC8379E, we should make a change to the
recommended setting from essentially nothing at this time to 0b001 for SATA.

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.

According to EHCI specification v1.0, the controller should stabilize
the power on a port at most 20 ms after the port power bit transition.
So, we put this setting in the virtual descriptor corresponding field,
(bPwrOn2PwrGood = 10 => 10 x 2ms = 20ms), this saves about 500ms at each
controller initialization/enumeration.

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.

U-boot itself generally builds with -nostdinc. This is because the
bootloader needs to be completely standalone. In the sandbox arch
though, we need a little bit of code to glue the u-boot world to the
host operating system, and we need to be able to access the host
libc's headers in order to do so.
Currently, we're using -I/usr/include to workaround the global
-nostdinc, but that doesn't work for everyone and for all headers.
Instead, let's filter out -nostdinc when building the os.c code.
Without this patch, some distros hit errors such as:
