boot_get_fdt() expects a uImage-wrapped FDT to be loaded to a staging
location, and then memmove()s it to the load address specified in the
header. This change enhances boot_get_fdt() to detect when the image has
already been loaded to the correct address, and skip this memmove(). The
detection algorithm was written to match the equivalent for the kernel;
see bootm_load_os()'s IH_COMP_NONE case.

The commit message of a28afca (Add uboot "fdt_high" enviroment variable)
states that fdt_high behaves similarly to the existing initrd_high.
But fdt_high actually has an outstanding difference from initrd_high.
The former specifies the start address, while the later specifies the
end address.
As fdt_high and initrd_high will likely be used together, it'd be nice
to have them behave same. The patch changes the behavior of fdt_high
to have it aligned with initrd_high.
The document of fdt_high in README is updated with an example to
demonstrate the usage of this environment variable.

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.

The legacy uImage format includes an absolute load and entry-point
address. When bootm operates on a kernel uImage in memory that isn't
loaded at the address in the image's load address, U-Boot will copy
the image to its address in the header.
Some kernel images can actually be loaded and used at any arbitrary
address. An example is an ARM Linux kernel zImage file. To represent
this capability, IH_TYPE_KERNEL_NOLOAD is implemented, which operates
just like IH_TYPE_KERNEL, except that the load address header is
ignored, and U-Boot does not copy the image to its load address, but
rather uses it in-place.
This is useful when sharing a single (uImage-wrapped) zImage across
multiple boards with different memory layouts; in this case, a specific
load address need not be picked when creating the uImage, but instead
is selected by the board-specific U-Boot environment used to load and
boot that image.

This patch adds a function getenv_bootm_mapsize() for obtaining the

The device tree (fdt) must always exist in within the bootmap (usually the
first 16MB of RAM). If it doesn't, then boot_relocate_fdt() will allocate
an LMB region in the bootmap and copy the fdt into that region. It will
also increase the size of the fdt.
If the fdt is already in the bootmap, then previously the memory was just
reserved. There was no contingency if the reservation failed, however.
By always allocating an lmb region and copying/resizing the fdt into that
region, the code is simplified and the memory region is always allocated
properly.
Also change the types of some variables to avoid some typecasts.

boot_relocate_fdt is called on platforms with CONFIG_SYS_BOOTMAPSZ
defined to relocate the device tree blob to be inside the
boot map area between bootmap_base and bootmap_base+CONFIG_SYS_BOOTMAPSZ.
For the case where the blob needs to be relocated, space is
allocated inside the bootmap by calling lmb_alloc_base with
size passed in plus some padding:
of_len = *of_size + CONFIG_SYS_FDT_PAD;
For the case where the blob is already inside the bounds of the boot map
area, lmb_reserve is called to reserve the the space where the blob is
already residing. The calculation for this case is currently:
of_len = (CONFIG_SYS_BOOTMAPSZ + bootmap_base) - (ulong)fdt_blob;
This is wrong because it reserves all the space in the boot map area
from the blob to the end ignoring completely the actual size. The
worst case is where the blob is at the beginning and the entire boot map
area get reserved. Fix this by changing the length calculation to this:
of_len = *of_size + CONFIG_SYS_FDT_PAD;
This bug has likely never manifested itself because bootm has never
been called with the fdt blob already in the bootmap area. In my
testing on an OMAP3 beagle board I initially worked around the bug
by simply moving the initial location of the fdt blob. I have tested
with the new calculation with the fdt blob both inside and outside
the boot map area.

Platforms with flat device tree support can use a bootmap to relocate
the fdt_blob. This is not a must. That's why the relocation function
boot_relocate_fdt() should be use only if CONFIG_OF_LIBFDT was defined
together with CONFIG_SYS_BOOTMAPSZ (see common/cmd_bootm.c).
On MicroBlaze platforms there is no need to use a bootmap to relocate
a fdt blob. So we need a more precise focus on the compilation and usage
of boot_relocate_fdt().
In general it is valid to exclude the function boot_relocate_fdt() if
the bootmap size CONFIG_SYS_BOOTMAPSZ is not defined.

If the user sets bootm_low and does not set bootm_size, u-boot will
report the memory node in the flat device tree incorrectly. Instead
of reporting the remaining size of memory, it will report the total
available memory which is incorrect.
Specifically this fixes the situation when booting a relocatable
kernel and the memory is reported as an offset and size in the
device tree, and the size needs to be adjusted accordingly.

The hush shell dynamically allocates (and re-allocates) memory for the
argument strings in the "char *argv[]" argument vector passed to
commands. Any code that modifies these pointers will cause serious
corruption of the malloc data structures and crash U-Boot, so make
sure the compiler can check that no such modifications are being done
by changing the code into "char * const argv[]".
This modification is the result of debugging a strange crash caused
after adding a new command, which used the following argument
processing code which has been working perfectly fine in all Unix
systems since version 6 - but not so in U-Boot:
int main (int argc, char **argv)
{
while (--argc > 0 && **++argv == '-') {
/* ====> */ while (*++*argv) {
switch (**argv) {
case 'd':
debug++;
break;
...
default:
usage ();
}
}
}
...
}
The line marked "====>" will corrupt the malloc data structures and
usually cause U-Boot to crash when the next command gets executed by
the shell. With the modification, the compiler will prevent this with
an
error: increment of read-only location '*argv'
N.B.: The code above can be trivially rewritten like this:
while (--argc > 0 && **++argv == '-') {
char *arg = *argv;

We don't actually need the kdb param as we are just using it to get
bd->bi_memsize which we can get from gd->bd->bi_memsize. Also, if we
boot via OF we might not actually fill out a kdb.

Dual format image code must properly handle all three FDT passing methods:
- raw FDT blob passed
- FDT blob embedded in the legacy uImage
- FDT blob embedded in the new uImage
This patch enables proper raw FDT handling when no FIT imaeg support
is compiled in. This is a bit tricky as we must dected FIT format even
when FIT uImage handling is not enabled as both FIT uImages and raw FDT
blobs use tha same low level format (libfdt).

Do not pass image verification flag directly to related routines.
Simplify argument passing and move it to the bootm_header structure which
contains curently processed image specific data and is already being passed
on the argument list.

When CONFIG_HAS_DATAFLASH is not defined gen_get_image() routine has nothing
to do, update its control flow to better reflect that simple case.

This patch adds framework for dual format images. Format detection is added
and the bootm controll flow is updated to include cases for new FIT format
uImages.
When the legacy (image_header based) format is detected appropriate
legacy specific handling is invoked. For the new (FIT based) format uImages
dual boot framework has a minial support, that will only print out a
corresponding debug messages. Implementation of the FIT specific handling will
be added in following patches.

Introducing routines for parsing new uImage format bootm arguments:
[<addr>]#<conf> - configuration specification
[<addr>]:<subimg> - subimage specification
New format images can contain multiple subimages of the same type. For example
a single new format image file can contain three kernels, two ramdisks and a
couple of FDT blobs. Subimage and configuration specifications are extensions
to bootm (and other image-related commands) arguments' syntax that allow to
specify which particular subimage should be operated on.
Subimage specification is used to denote a particular subimage. Configurations
are a bit more complex -- they are used to define a particualr booting setup,
for example a (kernel, fdt blob) pair, or a (kernel, ramdisk, fdt blob) tuple,
etc.

This routine assures that image (whether legacy or FIT) is not
in a special dataflash storage.
If image address is a dataflash address image is moved to system RAM.

This patch moves common pre-boot allocation steps shared between PPC
and M68K to a helper routines:
common:
- get_boot_sp_limit()
- get_boot_cmline()
- get_boot_kbd()
platform:
- set_clocks_in_mhz()

Ramdisk loading code, including initrd_high variable handling,
was duplicated for PPC and M68K platforms. This patch creates
common helper routine that is being called from both platform
do_bootm_linux() routines.
