LINUX KERNEL REVISION	VANILLA LINUX KERNEL	AT91 MAINTAINER PATCHSET	EXPERIMENTAL PATCHES
Linux 2.6.30	linux-2.6.30.tar.bz2	2.6.30-at91.patch.gz	2.6.30-at91-exp.tar.gz

Atmel给出的资源有以上三项内核源码为普通源代码，打上后面两个补丁包后可用于AT91的CPU上。关于补丁atmel的支持站点有以下说明：

Get and patch the Linux kernel

To get an experimental Linux4SAM kernel up and running on an AT91 product, you have to go through the following steps:

    1. identify on which linux kernel revision the experimental patches will apply 
    2. download the corresponding Linux kernel

    3. download the AT91 Maintainer's patch and apply it

    4. take the experimental patchset and apply it on top of the AT91 one

BEFORE LINUX 2.6.30 EXPERIMENTAL PATCHES

Download experimental patch: wget ftp://www.linux4sam.org/pub/linux/2.6.xx-at91-exp.patch.gz or wget ftp://www.linux4sam.org/pub/linux/2.6.xx.at91.y/2.6.xx.at91.y-exp.patch.gz And then: zcat linux-2.6.xx-at91-exp.diff.gz | patch -p1

LINUX 2.6.30 EXPERIMENTAL PATCHES AND ONWARDS

Download experimental patch archive: wget ftp://www.linux4sam.org/pub/linux/2.6.xx.at91/2.6.xx-at91-exp.y.tar.gz Decompress archive with: tar xvzf 2.6.xx-at91-exp.y.tar.gz And then apply patchset one patch after the other in proper order: for p in 2.6.xx-at91-exp.y/*; do patch -p1 < $p ; done

You will now have an updated copy of the experimental Linux4SAM kernel

第4步的说明和提供的资源无法匹配，要么是提供的资源不完整，要么是这段说明有问题，按照其说明无法完成操作，如ftp://www.linux4sam.org/pub/linux/2.6.xx-at91-exp.patch.gz　 ftp://www.linux4sam.org/pub/linux/2.6.xx.at91.y/2.6.xx.at91.y-exp.patch.gz等资源均不可用（xx已改为相应的版本号）。只好在其提供的两个补丁上要工夫，第一个补丁可以用zcat 轻松打上，但是第二个补丁2.6.30-at91-exp.tar.gz因格式不一样无法用此办法完成，tar –xzf 　2.6.30-at91-exp.tar.gz 后发现这是一组patch文件：

――这可能是ATMEL提供麻烦说明的原因。

需要找方便的方法一次性的把所有补丁打上，在LINUX一定会有这样的方法，仔细向下看，发现有：for p in 2.6.xx-at91-exp.y/*; do patch -p1 < $p ; done的语句，一个明显的循环语句，2.6.30-at91-exp.tar.gz解压后的目录名是2.6.30-at91-exp，将2.6.xx-at91-exp.y/*换为2.6.30-at91-exp后，一次打上了所有补丁。

此为一次打大量补丁的方法。
