From: Tien Fong Chee <tien.fong.chee@intel.com>

These series of patches enable peripheral bitstream being programmed into FPGA
to get the DDR up running. This's also called early IO release, because the
peripheral bitstream is only initializing FPGA IOs, PLL, IO48 and DDR.

Once DDR is up running, core bitstream from MMC which contains user FPGA
design would be loaded into DDR location. socfpga loadfs would be called to
program core bitstream into FPGA and entering user mode.

Lastly, u-boot-dtb.img from MMC FAT partition would be loaded to DDR, and up
running from there.

For this whole mechanism to work, the SDMMC flash layout would be designed as
shown in below:

RAW partition:
1. spl_w_dtb-mkpimage.bin
mkpimage -hv 1 -o spl/spl_w_dtb-mkpimage.bin spl/u-boot-spl-dtb.bin
spl/u-boot-spl-dtb.bin spl/u-boot-spl-dtb.bin spl/u-boot-spl-dtb.bin

FAT partition contains:
Bitstreams
----------
Early IO release method is recommended for the sake of performance, improve
up to 86% compare to full RBF.

1. ghrd_10as066n2.periph.rbf.mkimage
mkimage -A arm -T firmware -C none -O u-boot -a 0 -e 0 -n \"RBF\" -d
ghrd_10as066n2.periph.rbf ghrd_10as066n2.periph.rbf.mkimage

2. ghrd_10as066n2.core.rbf.mkimage
mkimage -A arm -T firmware -C none -O u-boot -a 0 -e 0 -n \"RBF\" -d
ghrd_10as066n2.core.rbf ghrd_10as066n2.core.rbf.mkimage

OR

1. ghrd_10as066n2.rbf.mkimage (full RBF)
mkimage -A arm -T firmware -C none -O u-boot -a 0 -e 0 -n \"RBF\" -d
ghrd_10as066n2.rbf ghrd_10as066n2.rbf.mkimage

For the testing purpose, these two patches are required to apply 1st before
applying this series of patches.
