[U-Boot] [PATCH v9 33/38] kbuild: use scripts/Makefile.clean
Masahiro Yamada

Tue Feb 4 09:24:40 CET 2014
This commit refactors cleaning targets such as
clean, clobber, mrpropper, distclean
with scripts/Makefile.clean.
By using scripts/Makefile.clean, we can recursively descend
into subdirectories and delete generated files there.
We do not need add a big list of generated files
to the "clean" target.

We can delete ugly stuff like follows:
clean:
@rm -f examples/standalone/atmel_df_pow2 \
examples/standalone/hello_world \
examples/standalone/interrupt \
examples/standalone/mem_to_mem_idma2intr \
examples/standalone/sched \
$(addprefix examples/standalone/, smc91111_eeprom smc911x_eeprom) \
examples/standalone/test_burst \
examples/standalone/timer
@rm -f $(addprefix examples/api/, demo demo.bin)
@rm -f tools/bmp_logo tools/easylogo/easylogo \
tools/env/fw_printenv \
tools/envcrc \
$(addprefix tools/gdb/, gdbcont gdbsend) \
tools/gen_eth_addr tools/img2srec \
tools/dumpimage \
$(addprefix tools/, mkenvimage mkimage) \
tools/mpc86x_clk \
$(addprefix tools/, mk$(BOARD)spl mkexynosspl) \
tools/mxsboot \
tools/ncb tools/ubsha1 \
tools/kernel-doc/docproc \
tools/proftool
@rm -f $(addprefix board/cray/L1/, bootscript.c bootscript.image) \
board/matrix_vision/*/bootscript.img \
spl/board/samsung/$(BOARD)/tools/mk$(BOARD)spl \
u-boot.lds \
$(addprefix arch/blackfin/cpu/, init.lds init.elf)
$(obj)arch/blackfin/cpu/init.{lds,elf}
By the way, I am keeping "make clobber" for now.
Do we need "make clobber"?
If we like 3-level cleaning targets, clean, mrproper, distclean,
like Linux Kernel, we can squash "clobber" to "clean".
Changes in v9:
- Describe "clean" and "clobber" more simply

Changes in v7: None
Changes in v6: None
Changes in v5:
- Remove "*.imx" and "*.map" files by pattern matching.
- Remove u-boot.elf
Changes in v4: None
Changes in v3: None
Changes in v2:
- Rebase on v2014.01-rc2 tag
