SPL: ARM: spear: Add SPL support for SPEAr600 platform
This patch adds SPL support for SPEAr600. Currently only SNOR (Serial NOR) flash support is included. Other boot devices (NAND, MMC, USB ...) may be added with later patches. Tested on the STM SPEAr600 evaluation and x600 SPEAr600 boards. Signed-off-by: Stefan Roese <sr@denx.de> Cc: Amit Virdi <amit.virdi@st.com> Cc: Vipin Kumar <vipin.kumar@st.com>
