From 0fcac1abde69a81ab1f773e41df612525c7d322a Mon Sep 17 00:00:00 2001 From: Rajeshwari Birje Date: Thu, 26 Dec 2013 09:44:27 +0530 Subject: SPL: EXYNOS: Prepare for variable size SPL support When variable size SPL is used, the BL1 expects the SPL to be encapsulated differently: instead of putting the checksum at a fixed offset in the SPL blob, prepend the blob with a header including the size and the checksum. The enhancements include - adding a command line option, '--vs' to indicate the need for the variable size encapsulation - padding the fixed size encapsulated blob with 0xff instead of random memory contents - do not silently truncate the input file, report error instead - no need to explicitly closing files/freeing memory, this all happens on exit; removing cleanups it makes code clearer - profuse commenting - modify Makefile to allow enabling the new feature per board Signed-off-by: Vadim Bendebury Signed-off-by: Rajeshwari S Shinde Acked-by: Simon Glass Signed-off-by: Minkyu Kang --- spl/Makefile | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'spl') diff --git a/spl/Makefile b/spl/Makefile index 2a787af..0caa982 100644 --- a/spl/Makefile +++ b/spl/Makefile @@ -166,8 +166,13 @@ endif all: $(ALL-y) ifdef CONFIG_SAMSUNG +ifdef CONFIG_VAR_SIZE_SPL +VAR_SIZE_PARAM = --vs +else +VAR_SIZE_PARAM = +endif $(obj)$(BOARD)-spl.bin: $(obj)u-boot-spl.bin - $(OBJTREE)/tools/mk$(BOARD)spl $< $@ + $(OBJTREE)/tools/mk$(BOARD)spl $(VAR_SIZE_PARAM) $< $@ endif $(obj)$(SPL_BIN).bin: $(obj)$(SPL_BIN) -- cgit v1.1
