[U-Boot] [PATCH 1/2] at91: move a/a/c/arm926ejs/at91/clock.c -> a/a/lib/at91

[Reinhard Meyer <u-boot@emk-elektronik.de>]

Dear Andreas Bie?mann,
> The at91/clock.c is copied from linux kernel and has support for both
> arm920t and arm926ejs core devices. Therefore this patch moves this
> generic at91/clock.c to a new place at arch/arm/lib/at91 to be used from
> at91 family devices.
> 
> We build a new libat91-common.o to provide the required symbols to both
> cpu types.

Please use the "git-mv" command to move the file "clock.c".

On any account, we should discuss about opening a subdir lib scheme first.
Currently arch/arm/lib does not have any subdirectories.

I _do_ see the problems of the current ARM directory structure which makes
the ARM core a more important criteria than SoC family especially in the
Atmel context where the SoCs have identical peripheral blocks but can have
different ARM cores.

Since that change goes outside the "Atmel directory domain",
I consider this an RFC. Albert is already on CC.

Best Regards,
Reinhard
