[U-Boot-Users] OS dependencies on the bootloader

[Andrew Wozniak]

Hello everyone,

A general bootloader question: How much hardware initialization should a 
bootloader perform for the target OS?

I see a minimal memory controller setup to allow subsequent loading of 
an OS image. ECC might also be setup but all remaining resources would 
typically be setup by the OS.

Although I haven't tried booting Linux (we boot the vxworks bootrom), 
does an embedded Linux make any assumptions about what the bootloader 
initializes?

Thank you and best regards, Andy
