sd卡移植 遇到的问题是插上mmc卡没有反应

忘了给/arch/arm/mach-s3c2440/mach-smdk2440.c中的
static struct platform_device *smdk2440_devices[] __initdata
添加sdi设备了，如下：
...
&s3c_device_i2c,
&s3c_device_iis,
&s3c_device_sdi, //加入这一行

～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～
移植sd卡的主要工作是通过打补丁来完成的
补丁地址：
http://svnweb.openmoko.org/*checkout*/branches/src/target/kernel/2.6.24.x/patches/s3c_mci.patch?rev=4096

再把补丁添加的s3cmci.c还要加入detect脚位，我选择的是S3C2410_GPG8。设定：
      static struct s3c24xx_mci_pdata s3cmci_def_pdata = {
       .do_dma        = 0,
       .gpio_detect    = S3C2410_GPG8,    //修改此处
       .set_power    = NULL,
       .ocr_avail    = MMC_VDD_32_33,
       };

【转】Ether Types

Ether Types (last updated 2008-09-09) NOTE: Please see [RFC5342] for current information and registration procedures. This registry will be revised soon and will be replaced with up-to-date information. Many of the networks of all classes are Ethernets (10Mb) or Experimental Ethernets (3Mb). These systems use a message "type" field in much the same way the ARPANET uses the "link" field. If you need an Ether Type, contact: IEEE Registration Authority IEEE Standards Department 445 Hoes Lane Piscataway, NJ 08854 Phone +1 732 562 3813 Fax: +1 732 562 1571 Email: <ieee-registration-authority& ieee.org > http://standards.ieee.org/regauth/index.html The following list of EtherTypes is contributed unverified information from various sources. Another list of EtherTypes is maintained by Michael A. Patton and is accessible at: <URL: http://www.cavebear.com/CaveBear/Ethernet/ > <URL: ftp://ftp.cavebear.com/pub/Ethernet-codes > Assign...
