stm32: stm32f7: add spl build support
This commit supports booting from stm32 internal nor flash. spl U-Boot initializes the sdram memory, copies next image (e.g. standard U-Boot) to sdram & then jumps to entry point. Here are the flash memory addresses for U-Boot-spl & standard U-Boot: - spl U-Boot : 0x0800_0000 - standard U-Boot : 0x0800_8000 To compile u-boot without spl: Remove SUPPORT_SPL configuration (arch/arm/mach-stm32/Kconfig) Signed-off-by: Vikas Manocha <vikas.manocha@st.com> [trini: Rework Kconfig logic a bit] Signed-off-by: Tom Rini <trini@konsulko.com>
