Note that this is off topic here. You should have posted this on  the
U-Boot-Users mailing list instead.

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:

	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.
