Hi everybody,
the current built-in environment in most i.MX boards is very similar.
Even if I always thought that the default environemt is something
that the user want always customize, I see from all you submitters
the not hidden desire to have such a common default environment for
all boards. At least, for i.MX boards.
Checking in the board configuration files, I see at least the following
boards that hase "quite" the same built-in environment:
mx23evk
mx23_olinuxino
mx28evk
mx51evk
mx53evk
mx53loco
mx53smd
mx6qarm2
mx6slevk
mx6qsabre* (all of them)
wandboard
cgtqmx6eval
hummingbird
udoo
and I am sure, I have missed some of them. The default environment is
quite the same, and CONFIG_EXTRA_ENV_SETTINGS is more or less a cut&paste
from another board. There are inconsistency and each fix must be repeated
for all boards.
I will try to address this issue. Maybe can we find a common built-in
environment,
that all other boards can simply include instead of redefining ?
I want to try to find some useful blocks, that we can reuse for each board
(mmc, nand, net,..).
Then each board could simply define something like:
+#include <configs/default_env.h>
#define CONFIG_EXTRA_ENV_SETTINGS \
CONFIG_BOARD_EXTRA_ENV_SETTINGS \
CONFIG_COMMON_SCRIPTS \
CONFIG_BOOTCOMMAND
Where CONFIG_BOARD_EXTRA_ENV_SETTINGS still contains extra defines specific
for the board
This patch is only a proposal: it is not complete and it want not to be. It is
for me only a way to start the discussion: how can we make order in the big
mess of built-in environment ?
Comments ?
Best regards,
Stefano Babic
