The 8544 DS doesn't have any cacheable Local Bus memories set up. By mapping
space for some anyway, we were allowing speculative loads into unmapped space,
which would cause an exception (annoying, even if ultimately harmless).
Removing LBC_CACHE_BASE, and using LBC_NONCACHE_BASE for the LBC LAW solves the
problem.

We need to wait while drawing engine clears frame
buffer before any further software accesses to frame
buffer will be initiated. Otherwise software drawn
parts could be partially destroyed by the drawing
engine or even GDC chip freeze could occur (as
observed on socrates board).

Microblaze and PowerPC use boot_get_ramdisk for loading
ramdisk to memory with checking return value.
Return 0 means success. Return 1 means failed.
Here is correspond part of code from bootm.c which check
return code.
ret = boot_get_ramdisk (argc, argv, images, IH_ARCH_PPC,
&rd_data_start, &rd_data_end);
if (ret)
goto error;

This patch removes some ft_board_setup() functions from some 4xx boards.
This can be done since we now have a default weak implementation for this
in cpu/ppc4xx/fdt.c. Only board in need for a different/custom
implementation like canyonlands need their own version.

Mail to kharris@nexus-tech.net bounces because the user doesn't exist
anymore. You can't be a maintainer without a valid e-mail address, so
move all boards that used to be maintained by Kyle Harris to the
"orphaned" list.
Currently, only PowerPC has a list of orphaned boards, so this patch
creates one for ARM as well.

On the at91sam9260ep development board there is an EEPROM
connected to the TWI interface (PA23, PA24 Peripheral A
multiplexing), so we cannot use these pins as ETX2, ETX3.
This patch configures PA10, PA11 pins for ETX2, ETX3
instead of PA23, PA24 pins.

The DIU_DIV register is 8 bit not 5 bit. This prevented large DIV values
so it was not possible to set a slow pixel clock and thus prevented
display on small screens.

This fixes the type pun warnings and makes the code

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.
