[PATCH] m32r - New architecure port to Renesas M32R processor

[PATCH] m32r - New architecure port to Renesas M32R processor

[Hirokazu Takata]

Hello, Linus and folks,

We have ported Linux to the M32R processor, which is a 32-bit RISC embedded
microprocessor of Renesas Technology.

I would like to release a patch information for this m32r port.
Would you merge them to the stock kernel?
# Unfortunately, I have linux-2.4.19 based kernel, not latest one.

Patch information is slightly bigger, so I placed it on our 
Linux/M32R homepage.
http://www.linux-m32r.org/public/linux-2.4.19_m32r_20040203.arch-m32r.patch

This new architecture port has already reported at OLS2003.

Thank you.

Nice!

However, I think you best upgrade to 2.4.25 first.
Also, please merge/move arch/m32r/drivers with/to drivers/.

And what about a 2.6 port? :-)

I attended that one, and it looked quite nice!

Geert,

Thank you for your quick reply.

I agree with you. I will try to upgrade it.

We have ported 2.6.0 kernel, and we are still working to add drivers. 
But I hope we can release it soon.  :-)

The m32r kernel also supports the wonderful features of 2.6 kernel 
like other architecture.
 - O(1) scheduler support
 - Preemtible kernel support
 - SMP support

for the latest 2.4.26 kernel.

Patch information to the stock linux-2.4.26 kernel is placed as follows:
- m32r architecture dependent portions (arch/m32r, include/asm-m32r)
  http://www.linux-m32r.org/public/linux-2.4.26_m32r_20040429.arch-m32r.patch
- architecture independent portions for the m32r
