York,
Just checking if you had seen this patch?
Yes, I noticed. You rename P2020RDB to P2020RDB_PC. Do you have another patch using P2020RDB?
It may be irrelevant. I have a p1020rdb-pb. So technically, unless we want to support p2020rdb-pb (which I don't have, and cannot test), you can ignore this one.
I have work here: https://github.com/bhundven/u-boot/tree/p1_p2_rdb-wip where I have reverted removing the p1_p2_rdb board, but have started to clean up the difference between p1_p2_rdb and p1_p2_rdb_pc. Eventually, it makes sense to me to move p1_p2_rdb_pc to p1_p2_rdb, as it has pc, and pd. If I can get time to finish, it would have p1020rdb-pb. Then just add the small difference for p1011rdb/p1020rdb-pb. What are your opinions on that?
I like clean and small changes.
The things that are difficult right now are:
- ddr(2) does not use spd on pb?
If I remember correctly, these boards have fixed DDR. RAW timing method was introduced to p1_p2_rdb_pc. You are welcome to use this method. It should be easy to back port.
- I have the ltib cds that came with the board, but I still feel like I'm missing a reference manual that is for the pb version. I can find the pc and pd versions of the 1020RM online. pb just seems a little different.
These boards are actually made by third parties. I have P1010RDB on my hand. If you need P1020RDB, I can find it for you.
Bryan,
I checked the last release for P1020RDB. It was on 2010-11-01. The schematic is included in the LTIB DVD under help/Hardware/P1020RDB.
Bryan,
Where are we on this patch? If you don't want to move forward, I can drop this for now.
