Logical partition on barebox

[Victorien Vedrine]

Thanks,

I debug common/partitions/dos.c and the problem is 
"dos_extended_partition() is not executed. I found why :
On dos_partition function there is a test to know the type of partition 
(line 212). The comment says "partition type 0x05 or 0x0f can be 
extended and just 0x0f is tested. The type extended partition on my SD 
card is 0x05 and then it doesn't work.
I modify the source code of common/partitions/dos.c with
             if ((pentry.dos_partition_type == 
0x0f)||(pentry.dos_partition_type == 0x05)) {
and now it's work.
