Add 'editenv' command

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

The editenv command can be used to edit an environment variable.
Editing an environment variable is useful when one wants to tweak an
existing variable, for example fix a typo or change the baudrate in the
'bootargs' environment variable.

setenv(): Delete 0-length environment variables

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

Previously setenv() would only delete an environment variable if it
was passed a NULL string pointer as a value.  It should also delete an
environment variable when it encounters a valid string pointer of
0-length.

This change/fix is generally useful and is necessary for the upcoming
"editenv" command.

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.

Revert "env: only build env_embedded and envcrc when needed"

2009-10-27T19:46:31+00:00

Breaks building on many boards, and no really clean fix available yet.

This reverts commit 6dab6add2d8ee80905234b326abc3de11be1d178.

fdt_support: Add multi-serial support for stdout fixup

2009-10-27T02:35:50+00:00

Currently fdt_fixup_stdout() is using hard-coded CONFIG_CONS_INDEX
constant. With multi-serial support, the CONS_INDEX may no longer
represent actual console, so we should try to extract port number
from the current stdio device name instead of always hard-coding the
constant value.

fdt: Fix fdt padding issue for initrd mem_rsv

2009-10-24T20:39:51+00:00

Its possible that we end up with a device tree that happens to be a
particular size that after we call fdt_resize() we don't have any
space left for the initrd mem_rsv.

Fix this be adding a second mem_rsv into the size calculation.  We
had one to cover the fdt itself and we have the potential of adding
a second for the initrd.
