[U-Boot-Users] Re: Booting from ext2 partition

[Pavel Bartusek]

Hi Jerry, Wolfgang,

 > Recently a few of the folks on my team have asked me to implement a 
loader that can load the kernel from an ext2 partition.

A good starting point would be
http://students.ceid.upatras.gr/~gef/fs/lread10.zip
or
http://students.ceid.upatras.gr/~gef/fs/ext2tool.zip

Wolfgang, currently I have implementation of booting from Reiserfs for 
U-Boot 0.3.0. My question is: will you accept the patch for latest 
version of U-Boot or you are totally against next filesytstem support in 
U-Boot ?

Pavel

I will never reject an extension that is useful to  some  people  and
does not hurt all the others. If your extension can be turned off (by
compile-time configuration options) completely I see no reason not to
add it.

My personal opinion is that such features are  more  or  less  wasted
effort,  since  the  same  result is usually easily available without
this feature. But if the work has already been done, it would be even
worse NOT to make it available to others.

Best regards,

Wolfgang Denk

It is nice to hear such message :-)

Yes, it can.

You are right, _usually_ you can live with additional partition for 
kernel, but there can be a situation when we need boot directly from 
some filesystem.


Give me some time and I'll port the reiserfs stuff to the latest U-Boot 
and send it to this list.

Best regards

[U-Boot-Users] PATCH: Reisefs support

[Pavel Bartusek]

Hi Wolfgang,

Here is the promised patch for Reiserfs support. It is from GRUB and 
tested with the PPC440 CPU. The command interface is the same as for FAT:
reiserls <interface> <dev[:part]> [directory]
reiserload <interface> <dev[:part]> [addr] [filename] [bytes]

CHANGELOG:
  * Patch by Pavel Bartusek 21 Mar 2004
     - Add Reiserfs support


best regards

Space is big. You just won't believe how vastly, hugely, mind-
bogglingly big it is. I mean, you may think it's a long way down the
road to the drug store, but that's just peanuts to space.
