From 505dc1c6795ba0b80abf344bb6464cdc20774f44 Mon Sep 17 00:00:00 2001 From: Chee Hong Ang Date: Tue, 11 Aug 2020 21:52:30 +0800 Subject: [PATCH] Makefile: socfpga: Generate sfp file with 4 SPL images 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 Signed-off-by: Ley Foon Tan --- Makefile | 27 ++++++++++++++++++--------- 1 file changed, 18 insertions(+), 9 deletions(-) diff --git a/Makefile b/Makefile index 1de1f38..28c9f31 100644 --- a/Makefile +++ b/Makefile @@ -1574,21 +1574,30 @@ u-boot.spr: spl/u-boot-spl.img u-boot.img FORCE $(call if_changed,pad_cat) ifneq ($(CONFIG_ARCH_SOCFPGA),) +quiet_cmd_gensplx4 = GENSPLX4 $@ +cmd_gensplx4 = cat spl/u-boot-spl.sfp spl/u-boot-spl.sfp \ + spl/u-boot-spl.sfp spl/u-boot-spl.sfp > $@ || rm -f $@ +spl/u-boot-splx4.sfp: spl/u-boot-spl.sfp FORCE + $(call if_changed,gensplx4) + quiet_cmd_socboot = SOCBOOT $@ -cmd_socboot = cat spl/u-boot-spl.sfp spl/u-boot-spl.sfp \ - spl/u-boot-spl.sfp spl/u-boot-spl.sfp \ - u-boot.img > $@ || rm -f $@ -u-boot-with-spl.sfp: spl/u-boot-spl.sfp u-boot.img FORCE +cmd_socboot = cat spl/u-boot-splx4.sfp u-boot.img > $@ || rm -f $@ +u-boot-with-spl.sfp: spl/u-boot-splx4.sfp u-boot.img FORCE $(call if_changed,socboot) -quiet_cmd_socnandboot = SOCNANDBOOT $@ -cmd_socnandboot = dd if=/dev/zero of=spl/u-boot-spl.pad bs=64 count=1024 ; \ +quiet_cmd_gensplpadx4 = GENSPLPADX4 $@ +cmd_gensplpadx4 = dd if=/dev/zero of=spl/u-boot-spl.pad bs=64 count=1024 ; \ cat spl/u-boot-spl.sfp spl/u-boot-spl.pad \ spl/u-boot-spl.sfp spl/u-boot-spl.pad \ spl/u-boot-spl.sfp spl/u-boot-spl.pad \ - spl/u-boot-spl.sfp spl/u-boot-spl.pad \ - u-boot.img > $@ || rm -f $@ spl/u-boot-spl.pad -u-boot-with-nand-spl.sfp: spl/u-boot-spl.sfp u-boot.img FORCE + spl/u-boot-spl.sfp spl/u-boot-spl.pad > $@ || \ + rm -f $@ spl/u-boot-spl.pad +u-boot-spl-padx4.sfp: spl/u-boot-spl.sfp FORCE + $(call if_changed,gensplpadx4) + +quiet_cmd_socnandboot = SOCNANDBOOT $@ +cmd_socnandboot = cat u-boot-spl-padx4.sfp u-boot.img > $@ || rm -f $@ +u-boot-with-nand-spl.sfp: u-boot-spl-padx4.sfp u-boot.img FORCE $(call if_changed,socnandboot) endif -- 2.7.4
