Instead of building a built-in.o file, you may also Objects listed with obj-* is used for modules or

This is normally not necessary and only used in lib/ and There is also the possibility to list objects that will

Only the name lib.a is allowed. All objects listed with lib-y are combined in a single
library for that directory.
Objects that are listed in obj-y and additional listed in
lib-y will not be included in the library, since they will anyway
be accessible.
For consistency objects listed in lib-m will be included in lib.a.
Note that the same kbuild makefile may list files to be built-in
and to be part of a library. Therefore the same directory
may contain both a built-in.o and a lib.a file.
Example: Example:
#arch/i386/lib/Makefile #arch/i386/lib/Makefile
L_TARGET := lib.a lib-y := checksum.o delay.o
obj-y := checksum.o delay.o
This will create a library lib.a based on checksum.o and delay.o. This will create a library lib.a based on checksum.o and delay.o.
For kbuild to actually recognize that there is a lib.a being build
the directory shall be listed in libs-y.
See also "6.3 List directories to visit when descending".
Usage of lib-y is normally restricted to lib/ and arch/*/lib.

The work in this architecture (ARM26) is that of a great many people.
This is what has happened:
I [Ian Molton] have been trying to repair the ARM26 architecture support, but it has become an impossible task whilst it is still merged with the ARM32 (arch/arm) code. The ARM26 code is too different to be sensible to keep with the ARM32 code now, and Russell King really doesnt have the time to maintain the ARM26 code. Add to that that most ARM32 developers dont know about or care about ARM26 when writing patches, and you have a reall mess.
As a result, I've split it off into a new architecture of its own. I've named it arm26 since these CPUs have only a 26 bit address space, unlike the other ARMs.
The upheaval in moving around so many source files and chopping out vasty ammounts of cruft was enormous, and the copyright of many files is sometimes unclear. Because of this, I am writing this, in order that no-one is left out / misaccredited / blamed for any of the code.
People I KNOW have made major contributions to the code:
David Alan Gilbert (former maintainer of ARM26 bits)
Philip Blundell
Russell King
Keith Owens
Currently maintaing the code are
Ian Molton (Maintainer / Archimedes)
John Appleby (kernel / A5K)
If anyone has a problem with attributions in header files / source files, please do contact me to straighten things out.

* FIQ support written by Philip Blundell <philb@gnu.org>, 1998.
*
* FIQ support re-written by Russell King to be more generic
*
* We now properly support a method by which the FIQ handlers can

* the FIQ vector itself.
*
* Operation is as follows:
* 1. Owner A claims FIQ:
* - default_fiq relinquishes control.
* 2. Owner A:
* - inserts code.
* - sets any registers,
* - enables FIQ.
* 3. Owner B claims FIQ:
* - if owner A has a relinquish function.
* - disable FIQs.
* - saves any registers.
* - returns zero.
* 4. Owner B:
* - inserts code.
* - sets any registers,
* - enables FIQ.
* 5. Owner B releases FIQ:
* - Owner A is asked to reacquire FIQ:
* - inserts code.
* - restores saved registers.
* - enables FIQ.
* 6. Goto 3
