06283a6401 Add pxe command
Add pxe command, which is intended to mimic PXELINUX functionality.
'pxe get' uses tftp to retrieve a file based on UUID, MAC address or IP
address. 'pxe boot' interprets the contents of PXELINUX config like file
to boot using a specific initrd, kernel and kernel command line.

This patch also adds a README.pxe file - see it for more details on the
pxe command.

09c2e90c11 unify version_string
This patch removes the architecture specific implementation of
version_string where possible. Some architectures use a special place
and therefore we provide U_BOOT_VERSION_STRING definition and a common
weak symbol version_string.

Add an address parameter to update_tftp(). If this address is non-zero,
skip the TFTP transfer and use the image at this address.

722b061b6f autocomplete: remove runtime handler install
Rather than add runtime overhead of installing completion handlers, do it
statically at build time.  This requires a new build time helper macro to
declare a command and the completion handler at the same time.  Then we
convert the env related funcs over to this.

This gives an opportunity to also unify the U_BOOT_CMD macros.

No need to output spaces 1 char at a time in a loop when the printf code

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) {
			...

143cd21fe2 Move CONFIG_UPDATE_TFTP code after CONFIG_PREBOOT
The auto-update feature (CONFIG_UPDATE_TFTP) requires that the env
variable serverip be set for the TFTP access. If DHCP is to be used
to get the serverip env variable, this doesn't work as DHCP happens
after the auto-update attempt has run. A solution is to run DHCP in
PREBOOT, but even this is too late.

To solve this, we move update_tftp() below the PREBOOT stuff.

ecc5500ee4 readline(): Add ability to modify a string buffer
If the 'buf' parameter is a non-0-length string, its contents will be

user entered its contents from scratch.

This change is necessary to support the upcoming "editenv" command but
could also be used for future commands which require a user to modify

e491a71e57 Check for NULL prompt in readline_into_buffer()
Previously, passing readline() or readline_into_buffer() a NULL 'prompt'
parameter would result in puts() printing garbage when
CONFIG_CMDLINE_EDITING was enabled.

Note that no board currently triggers this bug.  Enabling
CONFIG_CMDLINE_EDITING on some boards (eg bab7xx) would result in
the bug appearing.  This change is only intended to prevent someone
from running into this issue in the future.

81473f6781 hush: add showvar command for hush shell.
This new command shows the local variables defined in
the hush shell:

=> help showvar
showvar
    - print values of all hushshell variables
showvar name ...
    - print value of hushshell variable 'name'

Also make the set_local_var() and unset_local_var ()
no longer static, so it is possible to define local
hush shell variables at boot time. If CONFIG_HUSH_INIT_VAR
is defined, u-boot calls hush_init_var (), where
boardspecific code can define local hush shell
variables at boottime.

dc4b0b38d4 Fix printf errors.
The compiler will help find mismatches between printf formats and
arguments if you let it.  This patch adds the necessary attributes to
declarations in include/common.h, then begins to correct the resulting
compiler warnings.  Some of these were bugs, e.g., "$d" instead of
"%d" and incorrect arguments.  Others were just annoying, like
int-long mismatches on a system where both are 32 bits.  It's worth
fixing the annoying errors to catch the real ones.
