Dear Wolfgang Denk,
For the fix, I see an ugly multiline #if defined(AT91SAM9260) || defined(AT91SAM9G20) || ... coming into arch/arm/asm/global_data.h.
There is no common defined value for all AT91 SoCs that could be used.
If this is really for all AT91 SoCs, then please feel free to introduce a common define (CONFIG_SYS_AT91 ?) and use that. Eventually you can clean up some other such #if's on the way.
That would have to be set either in each board.h file or in each at91*.h file.
Probably there is a header file common to all AT91 SoCs when then can use a single such construct to #define the new variable so you don;t have to touch all the many board config files.
The only files I can see included in each instance are those of the kind hardware.h, memory_map.h and similiar. The define does not really belong in any of those.
I did the changes of adding the clock values to gd, and it became somewhat better, but there are still issues pending:
1. NAND accesses cause "raise: Signal # 8 caught" but still work, kernel boots normally. 2. environment is still invalid - when I boot the "CONFIG_SYS_ARM_WITHOUT_RELOC" version the ENV is ok. 3. saveenv goes way to fast to do anything and i2c md 57 1000.2 100 shows no change 4. env default -f hangs the system
Q: after relocation, "gd->" values are still available, right?
I am searching for further "violations"...
