kbuild: rename hostprogs-y/always to hostprogs/always-y

In old days, the "host-progs" syntax was used for specifying host
programs. It was renamed to the current "hostprogs-y" in 2004.

It is typically useful in scripts/Makefile because it allows Kbuild to
selectively compile host programs based on the kernel configuration.

This commit renames like follows:

always -> always-y
hostprogs-y -> hostprogs

So, scripts/Makefile will look like this:

always-$(CONFIG_BUILD_BIN2C) += ...
always-$(CONFIG_KALLSYMS) += ...
...
hostprogs := $(always-y) $(always-m)

I think this makes more sense because a host program is always a host
program, irrespective of the kernel configuration. We want to specify
which ones to compile by CONFIG options, so always-y will be handier.

The "always", "hostprogs-y", "hostprogs-m" will be kept for backward
compatibility for a while.

This is 597 - done utilising the variable hostprogs-y. 598 + done utilising the variable "hostprogs". 598 599 599 600 The second step is to add an explicit dependency to the executable. 600 601 This can be done in two ways. Either add the dependency in a rule, 601 - or utilise the variable $(always). 602 + or utilise the variable "always-y". 602 603 Both possibilities are described in the following. 603 604 604 605 4.1 Simple Host Program ··· 611 612 612 613 Example:: 613 614 614 - hostprogs-y := bin2hex 615 + hostprogs := bin2hex 615 616 616 617 Kbuild assumes in the above example that bin2hex is made from a single 617 618 c-source file named bin2hex.c located in the same directory as ··· 629 630 Example:: 630 631 631 632 #scripts/lxdialog/Makefile 632 - hostprogs-y := lxdialog 633 + hostprogs := lxdialog 633 634 lxdialog-objs := checklist.o lxdialog.o 634 635 635 636 Objects with extension .o are compiled from the corresponding .c ··· 649 650 Example:: 650 651 651 652 #scripts/kconfig/Makefile 652 - hostprogs-y := qconf 653 + hostprogs := qconf 653 654 qconf-cxxobjs := qconf.o 654 655 655 656 In the example above the executable is composed of the C++ file ··· 661 662 Example:: 662 663 663 664 #scripts/kconfig/Makefile 664 - hostprogs-y := qconf 665 + hostprogs := qconf 665 666 qconf-cxxobjs := qconf.o 666 667 qconf-objs := check.o 667 668 ··· 709 710 Example:: 710 711 711 712 #drivers/pci/Makefile 712 - hostprogs-y := gen-devlist 713 + hostprogs := gen-devlist 713 714 $(obj)/devlist.h: $(src)/pci.ids $(obj)/gen-devlist 714 715 ( cd $(obj); ./gen-devlist ) < $< 715 716 ··· 717 718 $(obj)/gen-devlist is updated. Note that references to 718 719 the host programs in special rules must be prefixed with $(obj). 719 720 720 - (2) Use $(always) 721 + (2) Use always-y 721 722 722 723 When there is no suitable special rule, and the host program 723 - shall be built when a makefile is entered, the $(always) 724 + shall be built when a makefile is entered, the always-y 724 725 variable shall be used. 725 726 726 727 Example:: 727 728 728 729 #scripts/lxdialog/Makefile 729 - hostprogs-y := lxdialog 730 - always := $(hostprogs-y) 730 + hostprogs := lxdialog 731 + always-y := $(hostprogs) 731 732 732 733 This will tell kbuild to build lxdialog even if not referenced in 733 734 any rule. 734 - 735 - 4.6 Using hostprogs-$(CONFIG_FOO) 736 - --------------------------------- 737 - 738 - A typical pattern in a Kbuild file looks like this: 739 - 740 - Example:: 741 - 742 - #scripts/Makefile 743 - hostprogs-$(CONFIG_KALLSYMS) += kallsyms 744 - 745 - Kbuild knows about both 'y' for built-in and 'm' for module. 746 - So if a config symbol evaluates to 'm', kbuild will still build 747 - the binary. In other words, Kbuild handles hostprogs-m exactly 748 - like hostprogs-y. But only hostprogs-y is recommended to be used 749 - when no CONFIG symbols are involved. 750 735 751 736 5 Kbuild clean infrastructure 752 737 ============================= 753 738 754 739 "make clean" deletes most generated files in the obj tree where the kernel 755 740 is compiled. This includes generated files such as host programs. 756 - Kbuild knows targets listed in $(hostprogs-y), $(hostprogs-m), $(always), 757 - $(extra-y) and $(targets). They are all deleted during "make clean". 758 - Files matching the patterns "*.[oas]", "*.ko", plus some additional files 759 - generated by kbuild are deleted all over the kernel src tree when 760 - "make clean" is executed. 741 + Kbuild knows targets listed in $(hostprogs), $(always-y), $(always-m), 742 + $(always-), $(extra-y), $(extra-) and $(targets). They are all deleted 743 + during "make clean". Files matching the patterns "*.[oas]", "*.ko", plus 744 + some additional files generated by kbuild are deleted all over the kernel 745 + source tree when "make clean" is executed. 761 746 762 747 Additional files or directories can be specified in kbuild makefiles by use of 763 748 $(clean-files).
