3 Subject: [PATCH] powerpc: boot: fix build with parallel make
4  
5 The powerpc boot wrapper Makefile is not parallel build safe, causing fixdep
6 to fail reading dependency files of the addnote, hack-coff and mktree
7 utilities when concurrently building different image targets.
8  
9 A typical failure looks like:

11 Building modules, stage 2.
12 HOSTCC arch/powerpc/boot/addnote
13 HOSTCC arch/powerpc/boot/hack-coff
14 DTC arch/powerpc/boot/taishan.dtb
15 HOSTCC arch/powerpc/boot/addnote
16 HOSTCC arch/powerpc/boot/hack-coff
17 MODPOST 800 modules

27 make[4]: *** [cuImage.taishan] Error 2
28 make[4]: *** Waiting for unfinished jobs....

30 Add a GNU make specific .NOTPARALLEL pseudo rule to enforce sequential building
31 of the addnote, hack-coff and mktree executables.
