With fewer #ifdefs the code is more readable and more of the code is
compiled for all boards. Add defines in the header file to control
what features are enabled, and then use if() instead of #ifdef.

and, if including libfdt.h which includes libfdt_env.h in
the correct order, don't include fdt.h before libfdt.h.
this is needed to get the fdt type definitions set from
the project environment before fdt.h uses them.

The bootm initrd image copy to ram can collide with the stack in cases
where the print buffer size is large (i.e. 1K). The result is intermittent
initrd decompression errors depending on the initrd size MOD 4KB since
the initrd start address is 4KB aligned.

Add an option, CONFIG_BOOTSTAGE_FDT to pass boot timings to the kernel
in the device tree, if available. To use this, you must have

Commit 0a672d4 "arm: Add Prep subcommand support to bootm" re-organized
do_bootm_linux for ARM. During the re-organization, the call to
fdt_fixup_ethernet() was removed. I assume this was useful, so add it
back.

This command boots Linux zImage from where the zImage is loaded to. Passing
initrd and fdt is supported.
Tested on i.MX28 based DENX M28EVK
Tested on PXA270 based Voipac PXA270.
NOTE: This currently only supports ARM, but other architectures can be easily
added by defining bootz_setup().

Adds prep subcommand to bootm implementation of ARM. When bootm is called
with the subcommand prep the function stops right after ATAGS creation and
before announce_and_cleanup.
This is used in command "cmd_spl export"

Add calls to bootstage before and after relocation, and just
before jumping to the OS.
The idea here is you can call bootstage_report() to get a report.
Additionally, if you define CONFIG_BOOTSTAGE_REPORT then a report is
printed automatically by U-Boot just before jumping to the kernel.

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 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) {
...
