I went ahead and did some moving of some files relating to the
AT91SAM9260 and the Olimex SAM9-L9260 development board. I also
created another file for the Olimex JTAG TINY that doesn't include
the 'A'. Apparently, the description for the JTAG tiny can differ
between Windows and Linux Operating Systems and this can make a
difference, so I figured it might be nice to have two of them.
Probably could do an include to reduce redundancy, but I'll leave
that decision to some one else.
Partial annoyance: the created patch file lists some files as having
a new property set called 'svn:mergeinfo', but their contents are not
included. Here is the 'svn status' on modified rev1333
R + src/target/target/at91sam9260.cfg
D src/target/target/at91sam9260minimal.cfg
A src/target/board/olimex_sam9_l9260.cfg
A + src/target/board/unknown-board-atmel-at91sam9260.cfg
A src/target/interface/olimex-jtag-tiny.cfg
Here is the general idea because the two new files are not fully
listed in the patch:
target/at91sam9260.cfgR1333 ->
board/unknown-board-atmel-at91sam9260.cfg
target/at91sam9260minimal.cfgR1333 -> target/at91sam9260.cfg
Actual patch file is attached. Some of the missing files are
attached as well.
