tools/env: fix redundant env flag comparison

2011-04-20T22:25:08+00:00

This fixes two bugs with comparison of redundant environment flags on
read.

flag0 and flag1 in fw_env_open() were declared signed instead of
unsigned char breaking BOOLEAN mode "== 0xFF" tests and in INCREMENTAL
mode the wrong environment would be chosen where the flag values are
127 and 128 (either way round). With both flags over 128, both signs
flipped and the logic worked by happy accident.

Also there was a logic bug in the INCREMENTAL test (after signedness was
fixed) in the case flag0=0, flag1=255, env 1 would be incorrectly chosen.

Fix both of these.

Add support for dataflash to U-boot environment settings tool.

2011-04-12T20:58:34+00:00

* The sector size for SPI-dataflash (like AT45 flashes) are not always
  a power-of-2. So, the sector calculations are rewritten such that it
  works for either power-of-2 as any size sectors.
* Make the flash sector size optional in case it is the same value as
  the environment size.

tools/env/fw_printenv: Make redundant env work on locked flashes also

2010-08-08T23:05:37+00:00

The invalidation of the old environment instance did not work for flashes
supporting hardware locking.  Now we unlock/lock around this update also.

Tools: set multiple variable with fw_setenv utility

2010-06-29T20:43:27+00:00

Add a sort of batch mode to fw_setenv, allowing to set
multiple variables in one shot, without updating the flash after
each set as now. It is added the possibility to pass
a config file with a list of pairs  to be set,
separated by a TAB character.

Adds two more ethernet interface to 83xx

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

Added as a convenience for other platforms that uses MPC8360 (has 8 UCC).
Six eth interface is chosen because the platform I am using combines
UCC1&2 and UCC3&4 as 1000 Eth and the other four UCCs as 10/100 Eth.

Propagate Error Status to the Shell on fw_printenv Errors

2008-05-09T21:40:40+00:00

Changed implementation such that fw_printenv returns failure status
when one or more specified variables do not exist or when incorrect
command syntax is used.

This aids scripting fw_printenv such that the script can key of the
return status rather than relying on standard error "scraping".
