Dear U-Boot community, I am looking for the User Manuals of the PPC405EXr and PPC460EX CPUs, but I can't find them.
There doesn't seem to be a document which fully describes the DDR2 interfaces and the bootstrapping via I2C for example, which is why I am hoping that it is somewhere in that UM. They are mentioned in the U-Boot source code all over the place, but they all seem lost. E.g., I have no idea how the clock/PLL is initialized in the case of an i2c bootstrap, as for the "kilauea" board. There is no explicit code which sets the clocks, it just reads them from a set of registers. So, what is the connection between a bunch of bytes and a set of registers and the final clock? Also, what are the default values? The same goes for the "canyonlands" board. If somebody could provide them to me, I would be very thankful. This is for a private project btw. Many thanks in advance and best regards, Daniel _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
