env: Add env_export() wrapper

2014-03-21T20:43:59+00:00

Implement env_export() wrapper, so that all implementers of saveenv() don't
have to call hexport_r(), crc32() etc. sequence . This trims down a bit of
code duplication.

env: dataflash: fix env_init issue

2013-10-14T20:06:52+00:00

As the SPI controller is not initialized before env_init(), it causes
reading env in dataflash failed. So, although saveenv() successfully,
it shows warning information when reboot the system as following:

  *** Warning - bad CRC, using default environment

Let the env_relocate() to check env CRC and import it.

Revert "env: fix potential stack overflow in environment functions"

2013-04-05T18:55:21+00:00

Wolfgang requested this be reverted and Rob agreed after further
discussion.  This was a symptom of a larger problem we need to deal
with.

This reverts commit 60d7d5a63189c9f77a190c9965861dc15482c2d0.

env: fix potential stack overflow in environment functions

2013-04-02T20:23:34+00:00

Most of the various environment functions create CONFIG_ENV_SIZE buffers on
the stack. At least on ARM and PPC which have 4KB stacks, this can overflow
the stack if we have large environment sizes. So move all the buffers off
the stack to static buffers.

env: Hide '.' variables in env print by default

2012-12-13T18:46:55+00:00

When printing all variables with env print, don't print variables that
begin with '.'.  If env print is called with a '-a' switch, then
include variables that begin with '.' (just like the ls command).

Variables printed explicitly will be printed even without the -a.

env: allow to export only selected variables

2011-11-08T12:20:42+00:00

New syntax:
	env export [-t | -b | -c] [-s size] addr [var ...]

With this change it is possible to provide a list of variables names
that shall be exported.  Whenno arguments are given, the whole
environment gets exported.

NOTE: The new handling of the "size" argument means a change to the
user API.

hashtable: drop all non-reentrant versions

2010-12-17T20:07:14+00:00

The non-reentrant versions of the hashtable functions operate on a single
shared hashtable.  So if two different people try using these funcs for
two different purposes, they'll cause problems for the other.

Avoid this by converting all existing hashtable consumers over to the
reentrant versions and then punting the non-reentrant ones.
