[PATCH] the nommu support for ARM linux 2.6.10

[Hyok S. Choi]

Hi all,
 
I'm glad to release the first MPU and NO-MMU support patch for ARM linux
2.6.10 at :
http://opensrc.sec.samsung.com/download/linux-2.6.10-hsc0.patch.gz

Previously, it was released as "armnommu" architecture which was called
uClinux/ARM and now is merged with "arm" architecture. You can select the
memory management type "MMU" for linux and "MPU" / "NONE" for uClinux at the
kernel configuration menu. Currently, the ATMEL, S5C7375, S3C24A0 platform
is tested.

I'm working on 2.6.11.5 patch, and it will be provided soon.
 
It would be great if you give me some suggestions.
 
Best Regards,
Hyok

[PATCH] the nommu support for ARM linux 2.6.10

[Hyok S. Choi]

An updated MPU and noMMU support patch for ARM against linux 2.6.10 kernel
is available at :

http://opensrc.sec.samsung.com/download/linux-2.6.10-hsc1.patch.gz

You can select the memory management type "MPU" or "NONE" in the arm kernel
configuration menu, which was traditionally known as "armnommu" or
uClinux/ARM by 2.6.9. (sure, you can choose "MMU" for vanila Linux :-)

It's a different way from other uclinux arch. (i.e. m68knommu), which
enables simultaneous support to use "singular address space" support even
for MMU platforms.
You can choose "MMU" or "NONE" for your mmu based arm platform with a few
modification. i.e. virtual address --> physical address conversion.

the 2.6.11.6-hsc0 patch will be available in this week, and some benchmark
will be provided for both cases on a same h/w platform.
and addtional MPU support API is pending for some services like memory
protection, even for uClinux.

any suggesstions welcomed.

You can reach the project home at : http://opensrc.sec.samsung.com/

currently officially supported platforms are : s3c24a0, s5c7375, atmel,
espd_s3c510b, P2001, s3c3410, s3cb0x.
