Changelogs:
-v4:
v3 got "Reviewed-by: Arnd Bergmann <arnd@arndb.de>"
stopping the 0xffffffff madness for IO_SPACE_LIMIT
fix .map_io compiling issue in the 1st patch
fix set_next_event in timer.c
rename GPU, USB, multimedia and SATA nodes in DTS
delete redundant 0x in DTS
-v3:
full DT file
delete all static mapping table in common.c
rename common.c to prima2.c
delete board file board_dt.c
split DEBUG_LL and L2 cache to seperate patch
-v2:
1. clock: use dev_id instead of con_id
2. Kconfig: delete ISA_DMA
3. irq: implement int controller based on DT
move to GENERIC_IRQ_CHIP framework
4. timer: implement timer based on DT
5. entry-macro.S: use get_irqnr_preamble to load the base address only once
per IRQ exception.
6. others:
use readl_relaxed instead of __raw_readl
adjust Kconfig order for PRIMA2
use clk_get_sys instead of clk_get for system level clock
use BUG_ON(IS_ERR(clk)) instead of BUG_ON(IS_ERR_OR_NULL(clk));
fix typo for CLOCK_TICK_RATE
("sirf,xxx", "sirf,prima2-xxx") instead of ("sirf,xxx") in dts
Note:
For L2 cache, if Rob's patch is merged, the whole file can be deleted

From: Binghua Duan <binghua.duan@csr.com>
SiRFprimaII is the latest generation application processor from CSR’s
Multifunction SoC product family. Designed around an ARM cortex A9 core,
high-speed memory bus, advanced 3D accelerator and full-HD multi-format
video decoder, SiRFprimaII is able to meet the needs of complicated
applications for modern multifunction devices that require heavy concurrent
applications and fluid user experience. Integrated with GPS baseband,
analog and PMU, this new platform is designed to provide a cost effective
solution for Automotive and Consumer markets.
This patch adds the basic support for this SoC and EVB board based on device
tree. It is following the ZYNQ of Grant Likely in some degree.

Note that when you get a 'Reviewed-by', 'Acked-by' or 'Tested-by'
reply to one of your mails, you should add that in the patch
changelog below your own 'Signed-off-by' in order to document
it for the future. This ususally still holds true when you make
further changes, just not when rewriting major parts of the patch.
For the Signed-off-by list, that should normally include only the
people that have handled the specific patch, it doesn't imply
authorship. Having seven people listed as Signed-off-by seems a bit
strange in this context, but there is no clear rule against it.
I would probably use 'Acked-by' or plain 'Cc' in the changelog for
some of the people, depending in what way they were involved.
At the least, you should have 'Signed-off-by' the person that wrote
most of the code, followed by the person that sends the patch at
the bottom of the list (as you did correctly).

i am sure i know reviewed-by/acked-by/tested-by should be added to the
end. what make me confused here is you are also the maintainer who
will merge these changes into arm-soc and finally make them pulled by
linus. generically,you will get the last signed-off-by too. if i list
"reviewed-by you", you might need to replace it by signed-off-by
finally.
anyway, i'm really not sure whether i am understanding right about that :-)

yes. i understand signed-off-by should only be given to people who
make the essential code changes in the special patch and people who
send or merge the special patch, but not the original author of the
original source files. for the 1st patch which is the basic board
support, in the long history of coding sirfprimaii, all the listed
people have contributed codes. so i get the names of all of them
shown. anyway, it is really too long....

The point is mostly that I tend to pull in patches from git, so I don't
add an explicit Signed-off-by to each patch. Also, the meaning of
Reviewed-by is stronger than just pulling a git tree, it means that
I looked at the code in much detail and am happy with the end result.
Simply pulling the patches can mean either that, or that I trust you
enough that I didn't bother looking (and/or don't care about the quality).

Not a problem. I basically wanted to make sure you know the rules,
and it seemed odd. It's probably ok to leave the list as it is.

ok, i see, thank!
i will add your reviewed-by to change log in the tree which i will use
to send pull request to you. we are building the opensource.csr.com
website. and i will place CSR's kernel there and build a for-arnd
branch. you can easily pull the for-arnd branch.
