[RFC/PATCH 0/7] ARCH: shmobile: defconfig consolidation

[RFC/PATCH 0/7] ARCH: shmobile: defconfig consolidation

[Simon Horman]

Hi,

this is a first pass at consolidating the defconfigs of shmobile.

It covers the mackerel, amradillo800eva and kzm9d boards which meet
the following criteria:

* Have the same base memory address (0x40000000).
* Work with RUNTIME_PM, it is desirable to have that a common defconfig
* Are booted via DT, enabling the command line to be supplied in the dts.
  This is important to allow serial console and early printk settings,
  which vary wildly between boards, to be supplied.
* Boards I have to test.
  This didn't eliminate any candidates that met the above criteria.

I believe it should also be possible to add support for the APE6EVM
board to the consolidated defconfig once problems with RUNTIME_PM
have been isolated and resolved. I have send an email about this
in a separate thread "APE6EVM and Runtime PM".

I believe it may be possible to add support for the lager board
to the consolidated defconfig once I am able to bring that board up,
which should be rather soon. The lager board does not currently
have a defconfig.

Morimoto-san, I suspect it may be possible to add support for the
bockw board to the consolidated defconfig if its boot loader supports
booting using a zImage. In this case even though the base memory address
is not the same as the boards above it should be possible to specify
the base address from the boot loader. As I do not have a bockw board
I am wondering if you could investigate this.

[RFC/PATCH 1/7] ARM: shmobile: prune defconfig

[Simon Horman]

Remove a number of lines from the shmobile defconfig as they seem to
be orthogonal to shmobile, not necessary for booting boards,
and as far as I know not present in a number of the shmobile
board defconfigs.

[RFC/PATCH 2/7] ARM: shmobile: make defconfig canonical

[Simon Horman]

Use make savedefconfig to update the defconfig to the current
canonical form.

This is to aid the process of adding support for other boards.

Do you know if there's any work being done on getting rid of the base memory 
address as a kernel config option ? It seriously hinders cross-SoC kernel 
testing.

As I understand things the main limitation is uImage which uses
the base memory address. There is some talk of creating uImages
at install time rather than build time. Which I believe would
remove most if not all the problem. However, its entirely unclear
to me what such an install process would look like. A new build target?
In tree script? Out of tree script? It seems very undefined to me.

Another, arguably better though not backwards compatible, option
is to boot using zImage (or even just Image) which do not rely
on the base address.

I'm not aware of any other work or discussion in this area although
it would not surprise me if there was some.

Don't we also need to get rid of CONFIG_MEMORY_START ? It's used in headsmp.S 
and headsmp-scu.S (through PLAT_PHYS_OFFSET).

Yes, I think so. Sorry for glossing over that.

I think it should be possible to remove that by evaluating it at runtime
somehow. But I have not though deeply about this.

Magnus,

ideally I would like to queue-up this series and request
it be included in v3.10 as a path to add defconfig support for the lager
baord (added as an 8th patch after my original posting of the series).

Can I get some feedback from you?

I tested shmobile_defconfig on Bock-W board.
It works with...

 1) I added R8A7778 SoC on .config
 2) I added Bock-W on .config
 3) I fixuped CONFIG_MEMORY_START, CONFIG_MEMORY_SIZE value on .config

It is correct method ?

Best regards

Unfortunately not, the idea is not to modify CONFIG_MEMORY_START
or CONFIG_MEMORY_SIZE.

My understanding is that if you load a zImage at the correct
start address (0x60000000 IIRC) and then execute it using bootz
then the kernel should relocate and run from that address.

Hmm...
This means 3) is not needed, but it didn't work without 3)
Is it R8A7778 or Bock-W DT code issue ?

Now, Bock-W start works with attached patch
Is it correct for you ?

I used simon/topic/defconfig-consolidation+next-20130403
(I guess there is no tag for it ?)
