[Qemu-devel] [PATCH] ARM920T CPU ID

[Daniel Silverstone]

Hi,

Attached is a patch which supplies the ARM920T CPU ID for ARM emulation.
This is another step along the way to supporting Simtec Electronics'
development boards, and other Samsung ARM9 SoC based systems such as the
Openmoko GTA02.

Regards,

Daniel.

ARM CPU ID: ARM920T

Simply put, this patch adds the ARM920T CPU ID as an option. This will
later be needed by the Samsung S3C24xx ARM9 SOCs.
