Hi all,
Here are some more patches, most notably the the possibility to merge
the default environment together from different directories. We can then
introduce a generic default environment which can be used from multiple
boards. Each board can make specific additions to this default environment.
Also, maybe this is controversal, the network stack now generates a random
MAC address if now valid address is found.
Sascha
The following changes since commit 52f760cd61e3f6ca6deb8e5c47eef168b598a674:
dhcp: do not call net_unregister if net_udp_new failed (2010-06-14 09:39:29 +0200)
are available in the git repository at:
git://git.pengutronix.de/git/barebox.git pu
Sascha Hauer (11):
pcm037: Add MMU support
bootu: Allow passing in devices as parameter
Allow to merge default environment from more than one directory
include support for a simple pseudo number generator
net: implement random_ether_addr
net: use a random mac address if the current device does not have one
add a generic default environment
pcm038: use generic default env
pcm043: use generic default env
pcm037: use generic default env
pca100: use generic default env

We have several nearly identical default environments in the tree.
Lets merge them to a single environment and use it on many boards.
This defaultenv is arm centric at the moment due to the use of arm
specific boot commands. This can be improved over time.

Wouldn't it be nice to load the initrd into /dev/ram0, too?

Any reason to not make this public and return int instead similar to
rand(3)?
We could presumably simply do:
#define RAND_MAX 255
And to be completely correct, these prototypes should be in stdlib.h
instead.

The reason was that I did not need rand but get_random_bytes and I
wasn't aware that rand() is that close to the corresponding libc
function.

Ok, will do.

Here is an updated version. I have put get_random_bytes() into
stdlib.h aswell, though of course this is no stdlib function.

next try...
We have several nearly identical default environments in the tree.
Lets merge them to a single environment and use it on many boards.
This defaultenv is arm centric at the moment due to the use of arm
specific boot commands. This can be improved over time.
changes since last version:
- fix potentially empty variable tests
- be a bit more verbose in boot script
- run a board specific init script (/env/bin/init_board) if it exists

The return value on this function seems wrong as it will always return a
value between 0 and 32767 irrespective of what RAND_MAX is set to which
doesn't agree with the comment on the function prototype.
Although it may just be me being dim as my hayfever is driving me mad today
:-)

I'm not sure if barebox supports the case statement. Even if not you
can simplify that to
if [ "x$1" = "xnand" ] || [ "x$1" = "xnor" ] || [ "x$1" = "xnet" ]; then
rootfs_loc="$1";
kernel_loc="$1";
fi
Best regards
Uwe

Well the way the rand function is implemented it is not suitable for
RAND_MAX > 32767. Ok, changed it for the attached patch.
I originally thought there would be discussion about the pros and cons
of random ethernet addresses, but about not this patch ;)
