Hi,

So I spend a day, "wrote" some init and relocation code and now U-Boot is starting directly from flash and relocates itself to RAM. No Preboot need ed. Nor gzipped image of U-Boot.
Thanks. I really appreciate this effort, especially since it allows to run a "pure" U-Boot on this architecture.
I would like to change the official U-Boot code for the AT91RM9200 and AT91RM9200DK so that it can be used without the need of another bootloader.
I''d appreciate such an effort.
Just for my understanding: the AT91RM9200DK is just one specific board usingt he AT91RM9200 (AT91RM9200DK == AT91RM9200 "D"evelopment "K"it?).
What do you think? Anyone interessted?
Yes, me :-)
I'd love to hear suggestion, where to put specific parts of the init code. Other ARM cpus use a board specific memsetup.S file. For an AT91RM9200 we have to setup more than just the SDRAM. Should we put all the init code into cpu/at91rm9200/{start.S} and use CON FIG_ and CFG_?
In cases where board-specific code is required the common code (like cpu/at91rm9200/start.S) should call board-specific init functions which will have to be implemented by code in the board dependend directories.
Or should every AT91 based board copy the same code again and again into thier own subdirectory?
NO !!!!
Best regards,
