博通AW-CM256SM最新驱动与补丁.rar

一.比对mmc/core/host.c.new和mmc/core/host.c.orig，将增加的代码段移植到内核， 注意配置"#define MMC_SDIO_SLOT 1",配置为板子对应的SLOT值 二.Wi-Fi驱动则需要调用bcm_sdio_detect. 驱动修改： 1.驱动Makefile里面定义一下 -DCUSTOMER_IMX 2.驱动如下这段 #if defined(CUSTOMER_IMX) //Eden Kuang mmc card detect extern void wifi_card_detect(bool); int wifi_platform_bus_enumerate(wifi_adapter_info_t *adapter, bool device_present) { int err = 0; struct wifi_platform_data *plat_data; if (!adapter) { pr_err("!!!! %s: failed! adapter variable is NULL!!!!!\n", __FUNCTION__); return -EINVAL; } DHD_ERROR(("%s device present %d\n", __FUNCTION__, device_present)); if (!adapter->wifi_plat_data) { wifi_card_detect(device_present); /* hook for card_detect */ } else { plat_data = adapter->wifi_plat_data; if (plat_data->set_carddetect) err = plat_data->set_carddetect(device_present); } return 0; /* force success status returned */ } 修改如下： extern void wifi_card_detect(bool); 改成 extern bcm_detect_card(int); if (!adapter->wifi_plat_data) { wifi_card_detect(device_present); /* hook for card_detect */ 改成 if (!adapter->wifi_plat_data) { bcm_detect_card(0); /* hook for card_detect */
