ef+dfu: Move EF image generation into separate makefile A separate makefile for EF (Entire Flash) targets allows the removal of board-specific hard-coded addresses. These values can now be included from the board-info.mk files for each board. 2012-02-04 18:03:42 +01:00			`#####`

ef: pad any gaps between the BL bank and the FW bank The Entire Flash (EF) image for revo has a gap between the end of the BL bank and the start of the FW bank. This fills the gap with 0xFF and properly aligns the FW image in flash. 2012-04-02 04:39:27 +02:00			`FW_PAD = $(shell echo $$[$(FW_BANK_BASE)-$(BL_BANK_BASE)-$(BL_BANK_SIZE)])`
			`$(OUTDIR)/$(TARGET).pad:`
makefile: add additional context to output when building all_* targets When building the various all_* targets, it was hard to tell which board/build-type that each line of output applied to. Now, the all_* target types will include something like: CC [fw\|cc ] flight/PiOS/STM32F10x/pios_gpio.c which includes the necessary additional context. This will help with identifying the context for warnings and errors when building a group of targets. 2012-06-03 02:31:57 +02:00			`$(V0) @echo $(MSG_PADDING) $@`
