Hello list,
inside the automatic U-Boot patch tracking system a new ticket [DNX#2006040142000811] was created:

Wolfgang Denk ha scritto:
Are there any particular reasons why this code should stay in start.S ?
Never change a running system without need?
Yeah, though not technical is an important one indeed ;-) But since a SoC structure has been created I thought it was nice to have all the independent files cleaned. Just give it a try! Anyway I'll fully understand if you prefer not to touch a running system.
Best regards -P.Broggini
