Updating git submodules.
SCONFIG mainboard/msi/b75a-ie35/devicetree.cb
ERROR: Unable to find device reference echi2
make: *** [Makefile.inc:638: build/mainboard/msi/b75a-ie35/static.c] Error 1
貌似是设备树的问题。
咋修啊？
https://github.com/daiaji/coreboot
这个是autoport写错了，是ehci而不是echi.
我已经改好了 https://review.coreboot.org/c/coreboot/+/72997

然后这个板子用了个不受支持的superio:F71868AD，这咋搞？
我有个PCI串口卡，能用来做串口命令行吗？

一般来说不添加superio的支持可能并不会影响启动，只是没法用串口调试，可能会有一定的功能缺失。
coreboot里面有fintek/f71869ad，不知道和F71868AD有多少区别，可以试一下。
PCI串口卡我不清楚在内存初始化之前能不能用。

superio不需要固件代码去识别设备，只需要直接配置。
我看了下f71869ad的功能，要在设备树配置的应该是风扇控制相关的功能。只用串口的话并不需要在设备树里加相关的描述。初始化串口应该是用 fintek_enable_serial 这个函数，它有两个参数 dev 和 iobase. 看了其他 superio 的用法，iobase 应该是用 CONFIG_TTYS0_BASE; dev 有点麻烦，你可能需要先找到 superio 用的端口（有可能是0x2e，如果superiotool能探测到最好，然而superiotool可能还没有支持你的芯片），还有串口设备对应的功能号（这个我觉得可能看一下f71869ad等类似芯片的datasheet可以找到点信息）。

mainboard_get_spd也有点问题。
只能识别一条内存。
第一条能识别。
我把第二条的插槽号换成1看看行不行。
频率也只有800Mhz。

Ivy Bridge 的话，用 inteltool -m 是可以看到很多信息的，你可以在原厂固件下用它看到你现有的内存对应的 channel 和 slot.

插槽号改成1就之后就直接不能引导了。

内核里的源码似乎是能够读取superio的数据。
有用吗？
由于能引导cbmem就能捕获数据。
日志可以看到了。

现在有两个方向，一个是老外说的LPC串口。（B75就没这玩意。）
另外一个是EHCI debug dongle。
前者不知道细节。
后者，我的RK3399开发板现在好像还能不能用Type-c口。
