* Support lazy install of sdk drivers This patch adds support for lazy install of Marvell prestera SDK drivers for platform-nokia. Lazy install for drivers is added as updated sdk driver needs to classify the drivers required for platform during compile time. SDK drivers and platform files are now fetched from a submodule(mrvl-prestera). Additionaly, DTB required for sonic_fit creation during compile time is sourced from sonic-linux-kernel. Signed-off-by: Pavan Naregundi <pnaregundi@marvell.com> * Add hugepage cmdline agrument Updated sdk & driver requries hugepage to be reserved during kernel boot. These kernel command line agrument are passed from installer.conf in device folder.
