你好，我正在寻找Linux补丁来支持S70GL02GS闪存。根据这个KB文章（Linux下的S70GL02GS支持-KBA218966），您必须创建一个支持案例来接收补丁。我已经这么做了，但到目前为止我只收到自动回复。我还感兴趣的是如何指定在加载时Linux解析的设备树源（.DTS）文件中的S70GL02GS。对于一个典型的CFI兼容的2MBIT、128MX16和Flash，我希望它的条目看起来像这样：NoFlash @ 0，0{地址单元＝& lt；0x1gt；大小的细胞= & lt；0x1gt；兼容=“CFI闪存”；Rg＝& lt；0x0 0x0 0x1000000；银行宽度= & lt；0x2 & gt；器件宽度＝＜0x1gt；但是S70GL02GS实际上是同一封装中的两个1Mb/Flash芯片（S29 GL01GS）。因此，有一个外部芯片选择，但内部有两个地址映射区域，它们具有独立的保护扇区和控制/状态寄存器。也许会有两个“Reg”声明来解释这两组控制寄存器，一个字节偏移量为0x8800。 以上来自于百度翻译 以下为原文Hi, I am looking for the Linux patch to support the S70GL02GS Flash.According to this KB article (S70GL02GS Support Under Linux - KBA218976 ), you have to create a Support Case to receive the patch.I have done so, but I have only received automated replies so far. I am also interested in how to specify the S70GL02GS in the Device Tree Source (.dts) file that Linux parses when it is loaded.For a typical CFI-compatible 2Mbit, 128Mx16 NOR Flash, I would expect its entry to look something like this: norflash@0,0 {#address-cells = ;#size-cells = ;compatible = "cfi-flash";reg = ;bank-width = ;device-width = ; But the S70GL02GS is actually two 1Mbit NOR Flash die (S29GL01GS) in the same package.So there is one external chip select, but internally there are two address-mapped regions that have independent protected sectors and control/status registers.Perhaps there would be two "reg" declarations to account for the two sets of control registers, one at byte offset 0x8000000?
