arm: add a common .lds link script
Most ARM CPUs use a very similar link script. This adds a basic
script that can be used by most CPUs.
Two new symbols are introduced which are intended to eventually be
defined on all architectures to make things easier for generic relocation
and reduce special-case code for each architecture:
__image_copy_start is the start of the text area (equivalent to the
existing _start on ARM). It marks the start of the region which must be
copied to a new location during relocation. This symbol is called
__text_start on x86 and microblaze.
__image_copy_end is the end of the region which must be copied to a new
location during relocation. It is normally equal to the start of the BSS
region, but this can vary in some cases (SPL?). Making this an explicit
symbol on its own removes any ambiguity and permits common code to always
do the right thing.
This new script makes use of CPUDIR, now defined by both Makefile and
spl/Makefile, to find the directory containing the start.o object file,
which is always placed first in the image.
To permit MMU setup prior to relocation (as used by pxa) we add an area
to the link script which contains space for this. This is taken
from commit 7f4cfcf. CPUs can put the contents in there using their
start.S file. BTW, shouldn't that area be 16KB-aligned?

Some devices can deal with multiple compatible properties. The devices
need to know which nodes to bind to which features. For example an
I2C driver which supports two different controller types will want to
know which type it is dealing with in each case.
The new fdtdec_add_aliases_for_id() function deals with this by allowing
the driver to search for additional compatible nodes for a different ID.
It can then detect the new ones and perform appropriate processing.
Another option considered was to return a tuple (node offset, compat id)
and have the function be passed a list of compatible IDs. This is more
overhead for the common case though. We may add such a function later if
more drivers in U-Boot require it.

fdt: Add basic support for decoding GPIO definitions
This adds some support into fdtdec for reading GPIO definitions from
the fdt. We permit up to FDT_GPIO_MAX GPIOs in the system. Each GPIO
is of the form:
gpio-function-name = <phandle gpio_num flags>;
where:
phandle is a pointer to the GPIO node
gpio_num is the number of the GPIO (0 to 223)
flags is a flag, as follows:
bit meaning
0 0=polarity normal, 1=active low (inverted)
An example is:
enable-propounder-gpios = <&gpio 43 0>;
which means that GPIO 43 is used to enable the propounder (setting the
GPIO high), or that you can detect that the propounder is enabled by
checking if the GPIO is high (the fdt does not indicate input/output).
Two main functions are provided:
fdtdec_decode_gpio() reads a GPIO property from an fdt node and decodes it
into a structure.
fdtdec_setup_gpio() sets up the GPIO by calling gpio_request for you.
Both functions can cope with the property being missing, which is taken to
mean that that GPIO function is not available or is not needed.
[For reference, from Stephen Warren <swarren@nvidia.com>. It may be that
we add this extra complexity later if needed:
The correct way to parse such a GPIO property in general is:
* Read the first cell.
* Find the node referenced by the phandle (the controller).
* Ensure property gpio-controller is present in the controller node.
* Read property #gpio-cells from the controller node.
* Extract #gpio-cells from the original property.
* Keep processing more cells from the original property; there may be
multiple GPIOs listed.
According to the binding documentation in the Linux kernel, Samsung
Exynos4 doesn't use this format, and while all other chips do have a
flags cell, about 50% of the controllers indicate the cell is unused.

fdt: Tidy up a few fdtdec problems
This fixes five trivial issues in fdtdec.c:
1. fdtdec_get_is_enabled() doesn't really need a default value
2. The fdt must be word-aligned, since otherwise it will fail on ARM
3. The compat_names[] array is missing its first element. This is needed
only because the first fdt_compat_id is defined to be invalid.
4. Added a header prototype for fdtdec_next_compatible()
5. Change fdtdec_next_alias() to only increment its 'upto' parameter
on success, to make the display error messages in the caller easier.

fdt: Add fdtdec_find_aliases() to deal with alias nodes
Stephen Warren pointed out that we should use nodes whether or not they
have an alias in the /aliases section. The aliases section specifies the
order so far as it can, but is not essential. Operating without alisses
is useful when the enumerated order of nodes does not matter (admittedly
rare in U-Boot).
This is considerably more complex, and it is important to keep this
complexity out of driver code. This patch creates a function
fdtdec_find_aliases() which returns an ordered list of node offsets
for a particular compatible ID, taking account of alias nodes.

omap-common/spl: Add linux boot to SPL
This adds Linux booting to the SPL
This depends on CONFIG_MACH_TYPE patch by Igor Grinberg
(http://article.gmane.org/gmane.comp.boot-loaders.u-boot/105809)
Related CONFIGs:
CONFIG_SPL_OS_BOOT
Activates/Deactivates the OS booting feature
CONFIG_SPL_OS_BOOT_KEY
defines the IO-pin number u-boot switch - if pressed u-boot is
booted
CONFIG_SYS_NAND_SPL_KERNEL_OFFS
Offset in NAND of direct boot kernel image to use in SPL
CONFIG_SYS_SPL_ARGS_ADDR
Address where the kernel boot arguments are expected - this is
normaly RAM-begin + 0x100

mx53: Make PLL2 to be the parent of UART clock
Change the parent UART clock to be PLL2, so that U-boot can also boot
a Freescale 2.6.35 kernel for mx53.
FSL kernel and U-boot changed the UART parent from PLL3 to PLL2 to avoid
conflicts with IPU clocks, so that the video resolution can be changed
without affecting the UART clock.
On a 2.6.35 kernel the serial console is messed up after IPU driver is loaded
and this patch fixes this problem.
Tested on a mx53loco board booting a FSL kernel and also a mainline kernel.
