How much of flexibility can be expected from the new DDR code? When
you submitted this patch, I verified that it works in the standard
configuration (with a 256 MB RAM module). Should it also work with
other configurations, say, with a 512 MB or a 1 GB module?
If I try it out, booting hangs here:
U-Boot 2008.10-rc3-00009-gf7a35a6 (Oct 18 2008 - 18:21:52)
CPU: 8541E, Version: 1.1, (0x807a0011)
Core: E500, Version: 2.0, (0x80200020)
Clock Configuration:
CPU: 660 MHz, CCB: 264 MHz,
DDR: 132 MHz (264 MT/s data rate), LBC: 66 MHz
CPM: 264 Mhz
L1: D-cache 32 kB enabled
I-cache 32 kB enabled
Board: Silicon Tx GPPP SSA Board
I2C: ready
DRAM: 512 MB
or:

I-cache 32 kB enabled

I2C: ready
DRAM: 1 GB
I.e., the size gets detected correctly, but then it hangs.
I know that the old code did not support other memory configurations;
should these work now with the new DDR code?
Best regards,
Wolfgang Denk

Everyone who comes in here wants three things:
1. They want it quick.
2. They want it good.
3. They want it cheap.
I tell 'em to pick two and call me back.
