The formula "counter = (u32) (gd->bus_clk / gd->baudrate) / 32"
can generate the wrong divisor due to integer division truncation.
Round the calculated divisor value by adding 1/2 the baudrate
before dividing by the baudrate.

This patch fixes a potentially serious issue related to USB which was
discouvered by Martin Krause <martin.krause@tqs.de> and fixed for
ARM920T. Martin wrote:
Turn off USB to prevent the host controller from writing to the
SDRAM while Linux is booting. This could happen, because the HCCA
(Host Controller Communication Area) lies within the SDRAM and the
host controller writes continously to this area (as busmaster!), for
example to increase the HccaFrameNumber variable, which happens
every 1 ms.
This is a slightly modified version of the patch in order to shutdown
USB when booting on all architectures.

This patch fixes bugs in usbdcore*.c related to the use of devices
with multiple configurations.
The original code made mistakes about the meaning of configuration value and
configuration index, and the resulting off-by-one errors resulted in:
* SET_CONFIGURATION always selected the first configuration, no matter what
wValue is being passed.
* GET_DESCRIPTOR/CONFIGURATION always returned the descriptor for the first
configuration (index 0).

This patch moves the check, if a device should be skipped in PCI PNP
configuration into the function pci_skip_dev(). This function is defined
as weak so that it can be overwritten by a platform specific one if
needed. The check if the device should get printed in the PCI summary upon
bootup (when CONFIG_PCI_SCAN_SHOW is defined) is moved to the function
pci_print_dev() which is also defined as weak too.

Newer PPC's like 440SPe, 460EX/GT can be equipped with more than 2GB of SDRAM.
To support such configurations, we "only" map the first 2GB via the TLB's. We
need some free virtual address space for the remaining peripherals like, SoC
devices, FLASH etc.
Note that ECC is currently not supported on configurations with more than 2GB
SDRAM. This is because we only map the first 2GB on such systems, and therefore
the ECC parity byte of the remaining area can't be written.

The compiler will help find mismatches between printf formats and
arguments if you let it. This patch adds the necessary attributes to
declarations in include/common.h, then begins to correct the resulting
compiler warnings. Some of these were bugs, e.g., "$d" instead of
"%d" and incorrect arguments. Others were just annoying, like
int-long mismatches on a system where both are 32 bits. It's worth
fixing the annoying errors to catch the real ones.
