>
> From: Guan Xuetao <guanxuetao@...c.pku.edu.cn>
>
> The whole patch could be fetched from:
> git://git.kernel.org/pub/scm/linux/kernel/git/epip/unicore32.git
> with branch name: unicore32.
> And it is divided into three patch sets: core architecture files,
> additional architecture files, and machine related files.
>
> This patch set adds the machine related files for UniCore32 ISA and PKUnity SoC.
>
> Patch 1 adds machine related core files, also including build infrastructure.
>
> Patch 2 add all hardware registers definitions, which are not split and inserted into
> different drivers.
>
> Patch 3 implements arch-specific pci bus driver.
>
> Patch 4 implements arch-specific ps2 dirver.
>
> Patch 5 implements frame buffer driver.
>
> Patch 6 implements ac97 driver.
>
> Patch 7 implements arch-specific i2c bus driver.
>
> Patch 8 implements network driver.
