Hello,
while porting U-Boot to Total5200 I thought that it would be nice if all MPC5200 and MGT5100 platforms could share their SDRAM initialization code. In fact this is already done but by means of code duplication. So far most people (everybody?) simply copied the board/icecube/icecube.c and took it SDRAM init code unchanged. And if the SDRAM chips themself were matching the appropriate mt4*-75.h file was copied as well. So how can we move the SDRAM init functions from the board directory to the drivers or the cpu/mpc5xxx directory? (I think cpu/mpc5xxx would be the better match)
In the Total5200 port I already went half way but taking the SDRAM init functions out from board/total/total5200.c to board/total5200/sdram.*. I did not put it into cpu/mpc5xxx because if I did so I wanted to have a smart solution in regards to coupling that with the SDRAM paramter includes (mt48lc16m16a2-75.h, mt46v16m16-75.h and mt48lc32m16a2-75.h).
Does anybody have an idea how we can make this generic for all MPC5200 and MGT5100 boards?
Regards Mark
