Generate 'u-boot-splx4.sfp' which consist of 4 SPL images required for booting up Cyclone5/Arria10. By default, this 'u-boot-splx4.sfp' is generated without extra padding after each SPL image. For Cyclone5, 'u-boot-splx4.sfp' contains: 4 x SPL(64KB) = 256KB For Arria10, 'u-boot-splx4.sfp' contains: 4 x SPL(256KB) = 1024KB For Cyclone5 using NAND flash image layout for 128 KB memory blocks, user can 'make' the following target to generate 4 SPL images with padding: make u-boot-spl-padx4.sfp 'u-boot-spl-padx4.sfp' contains four 128KB SPL images (each 64KB SPL is followed by 64KB of zero-padding). 4 x (SPL(64KB) + zero-padding(64KB)) = 512KB Signed-off-by: Chee Hong Ang <chee.hong.ang@intel.com> --- v3 changes: - add 'u-boot-splx4.sfp' make target (4 x SPL image without paddings) - add 'u-boot-spl-padx4.sfp' make target (4 x SPL image with 64KB paddings) - Update commit message (refer to commit message for details explanation) Makefile | 27 ++++++++++++++++++--------- 1 file changed, 18 insertions(+), 9 deletions(-)
