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

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
