readline(): Add ability to modify a string buffer

2009-10-27T19:58:25+00:00

If the 'buf' parameter is a non-0-length string, its contents will be
edited.  Previously, the initial contents of 'buf' were ignored and the
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
an existing string.

Check for NULL prompt in readline_into_buffer()

2009-10-27T19:58:25+00:00

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.

Remove inline qualifier from show_boot_progress()

2009-05-15T20:04:04+00:00

The 'inline' is conflicting with the semantic of 'weak' attribute and with the
way the show_boot_progress() function is used.

Also gcc 4.4 is complaining about it:

main.c:51: error: inline function 'show_boot_progress' cannot be declared weak

common/main: support bootdelay=0 for CONFIG_AUTOBOOT_KEYED

2009-01-24T00:24:15+00:00

Support bootdelay=0 in abortboot for the CONFIG_AUTOBOOT_KEYED case
similar to the CONFIG_ZERO_BOOTDELAY_CHECK support for the
!CONFIG_AUTOBOOT_KEYED case.

Do this by reversing the loop so we do at least one iteration before
checking for timeout.

hush: add showvar command for hush shell.

2008-10-18T19:54:02+00:00

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.

Automatic software update from TFTP server

2008-10-18T19:54:00+00:00

The auto-update feature allows to automatically download software updates
from a TFTP server and store them in Flash memory during boot. Updates are
contained in a FIT file and protected with SHA-1 checksum.

More detailed description can be found in doc/README.update.
