Dear Graeme Russ,
In message 4CDF2C8B.3060401@gmail.com you wrote:
You cannot and must not touch SDRAM in board_early_init_f(). And even more, you must not at all run relocate_code() there!
See: arch/powerpc/lib/board.c arch/m68k/lib/board.c arch/arm/lib/board.c
They all malloc the final global data structure, memcpy the temporary global data to the malloc'd global data, and call relocate_code passing a pointer to the new global data all at the very end board_init_f() and therefore after SDRAM has been initialised
Yes, and this is correct. board_init_f != board_early_init_f
Best regards,
Wolfgang Denk
