Tom Rini d024236e5a Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR
We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

Rebuilding u-boot for Cyrus

The Cyrus defconfigs are Cyrus_P5020_defconfig and Cyrus_P5040_defconfig.

They currently disable size optimization in order to avoid a relocation
bug in some versions of GCC. As the output size is a constant, the size
optimization is not currently important.

Cyrus boots off a microSD card in a slot on the motherboard. This requires
that the u-boot is built for the Pre-Boot Loader on the P5020/P5040.
In order to reflash u-boot, you must download u-boot.pbl, then write it
onto the card. To do that from u-boot:

> tftp 1000000 u-boot.pbl
> mmc write 1000000 8 672

If you want to do this via a card reader in linux:

> dd if=u-boot.pbl of=/dev/sdX bs=512 oseek=8
