PATCH 1/1 Add Freescale MX53 support

Thank you for this contribution! We certainly need more defconfigs.

Below are a few comments on your patch. Please consider them and if
necessary re-post it. If you will not be able to re-post it, let us know so someone else can adopt it.

We will certainly need a Signed-off-by tag on your patch, i.e. a line saying

Signed-off-by Your Name <[email protected]>

This is a short way for you to assert that you are entitled to contribute the patch under buildroot's GPL license. See
http://kerneltrap.org/files/Jeremy/DCO.txt for more details.

The processor is called "i.MX53", I believe. We also usually don't
include the vendor name in the processor identification. So something like configs/imx53loco_defconfig is probably more appropriate. OTOH, Freescale themselves seem to call i.MX3x processors "imx" and i.MX5x processors "mx5"...

Personally I'd prefer to use a kernel defconfig (mx5_defconfig), but
perhaps this one is more appropriate.

I think it is better (more predictable) to specify an exact version instead
of the latest HEAD. Either a git sha or a tarball, e.g.
http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/snapshot/rel_imx_2.6.38_12.01.01.tar.gz
(if that is a relevant snapshot at all).

mx53loco was afaik the internal code name for the board. Officially it's called the i.MX53 Quick Start Board
(http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=IMX53QSB),
but the mx53loco name is also used other places, like E.G. the kernel.

I don't really feel strongly about mx53loco vs imx53qsb though.

I think the main difference is that the mx5_defconfig includes several
BSPs, not just the loco. So this custom one will probably result in a (slightly) smaller kernel.

Which imho isn't a big priority for a defconfig (compared to the other issues for maintenance overhead, platform/driver support included, ..)

I agree if possible, as that's one thing less to maintain.

There are two differences between mx5_defconfig and this defconfig :
- mx5_defconfig include several BSPs which result in a failure in uImage building (multiple load addresses).
- CONFIG_MMC_BLOCK is set as module in mx5_defconfig. Since mx53 has no nand memory, this seemed relevant.

I agree if possible, as that's one thing less to maintain.

There are two differences between mx5_defconfig and this defconfig :
- mx5_defconfig include several BSPs which result in a failure in uImage building (multiple load addresses).
- CONFIG_MMC_BLOCK is set as module in mx5_defconfig. Since mx53 has no nand memory, this seemed relevant.

Fair enough. It would be good to document this in the log message.

Arnout

What does 'Binaries blob' mean?

By 'Binaries blob' I mean Freescale Multimedia Codecs. Current buildroot configuration will probably not allow users to use them.

The processor is called "i.MX53", I believe. We also usually don't
include the vendor name in the processor identification. So something like configs/imx53loco_defconfig is probably more appropriate. OTOH, Freescale themselves seem to call i.MX3x processors "imx" and i.MX5x processors "mx5"...

Ok for the vendor name.
For imx53/mx53 it seemed appropriate to name it mx53 since it's the name in kernel and u-boot.

I think it is better (more predictable) to specify an exact version instead
of the latest HEAD. Either a git sha or a tarball, e.g.
http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/snapshot/rel_imx_2.6.38_12.01.01.tar.gz

PATCH 1/1 Add Freescale MX53 support

Hi,

So, finally, I realized there IS a good kernel defconfig in freescale git, I just had to look in the right branch, not in master... sorry.

I hope I fixed all your comments about my patch (except maybe about mx53/imx53 name, I'm still not shure what is better). If some changes are still needed, please say so.

Given that this is the u-boot board name, I think mx53loco_defconfig is
indeed a good name.

I haven't looked at it, but isn't this a defconfig that requires a
device tree blob? Or is it just one that includes a number of devboard BSPs?
