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,

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.

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.

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.

- Rebased to current mainline
- Moved android image handling to separate functions in

If a specific configuraion is selected by the bootm command, e.g. with
'bootm 84000000#recoveryconf' we must honour this for not just the kernel,
but also the ramdisk and FDT.
In the conversion to using a common fit_image_load() function for loading
images from FITs (commits a51ec63 and 53f375f) this feature was lost.
Reinstate it by passing the selected configuration back from
fit_image_load() to boot_get_kernel(), then use this configuration
(which is stored in images->fit_uname_cfg) in both boot_get_ramdisk()
and boot_get_fdt().

At present the arguments to bootm are processed in a somewhat confusing
way. Sub-functions must know how many arguments their calling functions
have processed, and the OS boot function must also have this information.
Also it isn't obvious that 'bootm' and 'bootm start' provide arguments in
the same way.
Adjust the code so that arguments are removed from the list before calling
a sub-function. This means that all functions can know that argv[0] is the
first argument of which they need to take notice.

Much of the image code uses addresses as ulongs and pointers interchangeably,

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.

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

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.

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 avoids the following checkpatch warning in later patches:
ERROR: "(foo*)" should be "(foo *)"
ERROR: space required before the open brace '{'
ERROR: space prohibited before that close parenthesis ')'
ERROR: spaces required around that '||' (ctx:WxV)
WARNING: space prohibited between function name and open parenthesis '('

Add a new "fdt_high" enviroment variable. This can be used to control (or prevent) the

The previous patch makes u-boot use the full accessible size of ram as
the default boot mapped size if CONFIG_SYS_BOOTMAPSZ is not defined,
which means boot_relocate_fdt() can be changed to depend solely on
CONFIG_OF_LIBFDT.

This patch adds a function getenv_bootm_mapsize() for obtaining the
size of the early mapped region accessible by the kernel during early
boot. It defaults to CONFIG_SYS_BOOTMAPSZ, or if not defined,
defaults to getenv_bootm_size(), which in turn defaults to the size of
RAM.
getenv_bootm_mapsize() can also be overridden with a "bootm_mapsize"
environmental variable.

For the calls to boot_relocate_fdt(), boot_get_cmdline(), and
boot_get_kbd(), the value of bootmem_base is always obtained by
calling getenv_bootm_low(). Since the value always comes from the
same source, the calling signature for those functions can be
simplified by making them call getenv_bootm_low() directly.

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;
while (*++arg) {
switch (*arg) {
