Note that this is off topic here. You should have posted this on the

Thisi s wrong. The Yosemite configuration uses (like most (all?) AMCC
eval boards - two redundand flash sectors to store the environment.
And available environment size is 8 kB:
=> print
...
Environment size: 1355/8187 bytes

I have no idea where you got your board configuration from, but it is
definitely not current code, nor the binary image at
ftp://ftp.denx.de/pub/u-boot/images/amcc/yosemite/u-boot.bin
The current code does use (redundand) flash for environment storage.
