9734b97f76 image: Fix loop condition to avoid warning
GCC 5.1 starts warning for comparisons such as !a > 0, assuming that the
negation was meant to apply to the whole expression rather than just the
left operand.

Indeed the comparison in the FIT loadable code is confusingly written,
though it does end up doing the right thing. Rewrite the condition to be
more explicit, that is, iterate over strings until they're exhausted.

84a07dbfd8 add boot_get_loadables() to load listed images
Added a trimmed down instance of boot_get_<thing>() to satisfy the
minimum requierments of the added feature.  The function follows the
normal patterns set by other boot_get<thing>'s, which should make it a

function in a later refactor.

832472a94d tools: socfpga: Add socfpga preloader signing to mkimage
Like many platforms, the Altera socfpga platform requires that the
preloader be "signed" in a certain way or the built-in boot ROM will
not boot the code.

This change automatically creates an appropriately signed preloader
from an SPL image.

The signed image includes a CRC which must, of course, be generated
with a CRC generator that the SoCFPGA boot ROM agrees with otherwise
the boot ROM will reject the image.

Unfortunately the CRC used in this boot ROM is not the same as the
Adler CRC in lib/crc32.c. Indeed the Adler code is not technically a
CRC but is more correctly described as a checksum.

Thus, the appropriate CRC generator is added to lib/ as crc32_alt.c.

Commit e3a5bbce broke the FIT image tests by not loading a ramdisk even if

will be loaded if a non-zero load address is provided.

7b1a411743 mkimage: add atmelimage
The new atmelimage converts a machine code BLOB to bootable ROM image. Atmel
ROM has no sophisticated image format, it only checks the first 7 ARM vectors.
The vectors can contain valid B or LDR opcodes, the 6'th vector contains the
image size to load.

Additionally the PMECC header can be written by the atmelimage target. The
parameters must be given via the -n switch as a coma separated list. For
example:

mkimage -T atmelimage \
 -n usePmecc=1,sectorPerPage=4,sectorSize=512,spareSize=64,eccBits=4,eccOffset=36 \
 -d spl/u-boot-spl.bin boot.bin

A provided image can be checked for correct header setup. It prints out the
PMECC header parameters if it has one and the 6'th interrupt vector content.

---8<---
Image Type:	ATMEL ROM-Boot Image with PMECC Header
		PMECC header
		====================
		eccOffset:        36
		sectorSize:      512

9ace3fc814 image: add support for Android's boot image format
This patch adds support for the Android boot-image format. The header
file is from the Android project and got slightly alterted so the struct +
its defines are not generic but have something like a namespace. The
header file is from bootloader/legacy/include/boot/bootimg.h. The header
parsing has been written from scratch and I looked at
bootloader/legacy/usbloader/usbloader.c for some details.
The image contains the physical address (load address) of the kernel and
ramdisk. This address is considered only for the kernel image.
The "second image" defined in the image header is currently not
supported. I haven't found anything that is creating this.

v3 (Rob Herring):
This is based on http://patchwork.ozlabs.org/patch/126797/ with the
following changes:
- Rebased to current mainline
- Moved android image handling to separate functions in
  common/image-android.c
- s/u8/char/ in header to fix string function warnings
- Use SPDX identifiers for licenses
- Cleaned-up file source information:
  android_image.h is from file include/boot/bootimg.h in repository:
  https://android.googlesource.com/platform/bootable/bootloader/legacy
  The git commit hash is 4205b865141ff2e255fe1d3bd16de18e217ef06a
  usbloader.c would be from the same commit, but it does not appear
  to have been used for any actual code.
v4:
- s/andriod/android/
- Use a separate flag ep_found to track if the entry point has been set
rather than using a magic value.

In the conversion to using a common fit_image_load() function for loading

Reinstate it by passing the selected configuration back from
fit_image_load() to boot_get_kernel(), then use this configuration

Also it isn't obvious that 'bootm' and 'bootm start' provide arguments in
the same way.

35e7b0f179 sandbox: image: Add support for booting images in sandbox
Much of the image code uses addresses as ulongs and pointers interchangeably,
casting between the two forms as needed.

This doesn't work with sandbox, which has a U-Boot RAM buffer which is
separate from the host machine's memory.

Adjust the cost so that translating from a U-Boot address to a pointer uses
map_sysmem(). This allows bootm to work correctly on sandbox.

Note that there are no exhaustive tests for this code on sandbox, so it is
possible that some dark corners remain.

d95f6ec733 fdt: Add option to default to most compatible conf in a fit image
When booting a fit image with multiple configurations, the user either has to
specify which configuration to use explicitly, or there has to be a default
defined which is chosen automatically. This change adds an option to change
that behavior so that a configuration can be selected explicitly, or the
configuration which has the device tree that claims to be compatible with the
earliest item in U-Boot's device tree.

In other words, if U-Boot claimed to be compatible with A, B, and then C, and
the configurations claimed to be compatible with A, D and B, D and D, E, the
first configuration, A, D, would be chosen. Both the first and second
configurations match, but the first one matches a more specific entry in
U-Boot's device tree. The order in the kernel's device tree is ignored.

e37ae40e9d image: Support FDTs already loaded at their load address
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;

fa34f6b25b common/image.c: align usage of fdt_high with initrd_high
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

HW cache coherent with the secondary core that we are loading and

we've flushed the regions of memory utilized by ramdisk and device tree
so the loadding and any modifications (from decompression or fdt updates)

b9b50e89d3 image: Implement IH_TYPE_KERNEL_NOLOAD
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.

v2: Rename from IH_TYPE_KERNEL_ANYLOAD to IH_TYPE_KERNEL_NOLOAD.

43b08af53e always relocate fdt into an lmb-allocated memory block
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.

758b39979d common/image.c fix length calculation in boot_relocate_fdt
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.

958e120643 fdt relocate: have more attention to use a bootmap or not
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.

c519facc64 Fix condition where bootm_size not set and wrong memory size reported
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.

54841ab50c Make sure that argv[] argument pointers are not modified.
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;
		while (*++arg) {
			switch (*arg) {
			...

20dde48bca add lzop decompression support
Add lzop decompression support to the existing lzo bitstream handling
(think gzip versus zlib), and support it for uImage decompression if
CONFIG_LZO is enabled.

Lzop doesn't compress as good as gzip (~10% worse), but decompression
is very fast (~0.7s faster here on a slow ppc). The lzop decompression
code is based on Albin Tonnerre's recent ARM Linux lzo support patch.
