2016-09-27 22:41 GMT-07:00 Mike Looijmans <mike.looijmans@topic.nl>: > The Zynq/ZynqMP boot.bin file contains a region for register initialization > data. Filling in proper values in this table can reduce boot time > (e.g. about 50ms faster on QSPI boot) and also reduce the size of > the SPL binary. > > The table is a simple text file with register+data on each line. Other > lines are simply skipped. The file can be passed to mkimage using the > "-R" parameter. > > It is recommended to add reg init file to board folder. > For example: > CONFIG_BOOT_INIT_FILE="board/xilinx/zynqmp/xilinx_zynqmp_zcu102/reg.int > > Signed-off-by: Mike Looijmans <mike.looijmans@topic.nl> > Signed-off-by: Michal Simek <michal.simek@xilinx.com> > --- > v2: Add ${srctree} to initialisation path to fix out-of-tree builds > > arch/arm/cpu/armv8/zynqmp/Kconfig | 7 +++++++ > arch/arm/mach-zynq/Kconfig | 7 +++++++ > scripts/Makefile.spl | 4 ++-- > tools/zynqimage.c | 28 ++++++++++++++++++++++++++++ > tools/zynqmpimage.c | 28 ++++++++++++++++++++++++++++ > 5 files changed, 72 insertions(+), 2 deletions(-) > > diff --git a/arch/arm/cpu/armv8/zynqmp/Kconfig > b/arch/arm/cpu/armv8/zynqmp/Kconfig > index 1eedb39..a3baae4 100644 > --- a/arch/arm/cpu/armv8/zynqmp/Kconfig > +++ b/arch/arm/cpu/armv8/zynqmp/Kconfig > @@ -41,6 +41,13 @@ config SYS_CONFIG_NAME > Based on this option include/configs/<CONFIG_SYS_CONFIG_NAME>.h > header > will be used for board configuration. > > +config BOOT_INIT_FILE > + string "boot.bin init register filename" > + default "" > + help > + Add register writes to boot.bin format (max 256 pairs). > + Expect a table of register-value pairs, e.g. "0x12345678 0x4321" > + > config ZYNQMP_USB > bool "Configure ZynqMP USB" > > diff --git a/arch/arm/mach-zynq/Kconfig b/arch/arm/mach-zynq/Kconfig > index a1175ee..44e16af 100644 > --- a/arch/arm/mach-zynq/Kconfig > +++ b/arch/arm/mach-zynq/Kconfig > @@ -44,4 +44,11 @@ config SYS_CONFIG_NAME > config SYS_MALLOC_F_LEN > default 0x600 > > +config BOOT_INIT_FILE > + string "boot.bin init register filename" > + default "" > + help > + Add register writes to boot.bin format (max 256 pairs). > + Expect a table of register-value pairs, e.g. "0x12345678 0x4321" > + > endif > diff --git a/scripts/Makefile.spl b/scripts/Makefile.spl > index 5a7f79c..18436b9 100644 > --- a/scripts/Makefile.spl > +++ b/scripts/Makefile.spl > @@ -142,10 +142,10 @@ boot.bin: $(obj)/u-boot-spl.bin FORCE > $(call if_changed,mkimage) > else > ifdef CONFIG_ARCH_ZYNQ > -MKIMAGEFLAGS_boot.bin = -T zynqimage > +MKIMAGEFLAGS_boot.bin = -T zynqimage -R $(srctree)/$(CONFIG_BOOT_INIT_ > FILE) > endif > ifdef CONFIG_ARCH_ZYNQMP > -MKIMAGEFLAGS_boot.bin = -T zynqmpimage > +MKIMAGEFLAGS_boot.bin = -T zynqmpimage -R $(srctree)/$(CONFIG_BOOT_INIT_ > FILE) > endif > > spl/boot.bin: $(obj)/u-boot-spl.bin FORCE > diff --git a/tools/zynqimage.c b/tools/zynqimage.c > index c43bd5d..43876e7 100644 > --- a/tools/zynqimage.c > +++ b/tools/zynqimage.c > @@ -222,6 +222,30 @@ static int zynqimage_check_image_types(uint8_t type) > return EXIT_FAILURE;
