Re: [U-Boot-Users] [PATCH]: Fix for bug: U-boot environment corrupt by reading uninitialized flash memory instead of RAM.

Hmm...maybe this is a stupid question, but why can't it _always_ use the RAM area to look up the environment? env_init() is one of the first things to be called during bootstrap...

One of the first accesses to the environment happens when we need to read the console baudrate to initialize the serial interface. This happens very, very early in the initialization, long before RAM is even usable.

Maybe it's wishful thinking, but if we could get rid of this extra logic, u-boot would become simpler, smaller and faster, right?

Unfortunately this is not the case.
