dev_name is supposed to return the name of the device plus the id
currently we use %s%d format where in the kernel the use %s.%d
we may think to switch to this format for the device name and keeping the %s%d
for the devfs
this will be usefull to not modify the clock device name as example

as refer in this patch "arm & sh: factorised duplicated clkdev.c"
factorise some generic infrastructure to assist looking up struct clks
for the ARM & SH architecture.
as the code is identical at 99% in linux
move it also as preparing for the SH adding

Show a '%w' or %W thing.
This will show a frequency or byte at format xxx[.xxx] [ kMG]
the precision can not excess the base kMG of the current unit
otherwise it will be automatically reduce
if no precision is specified and there is rest we will use a default
precision of 3 as 66.667 M
base will be typically 1000 for Hz or B and 1024 for iB

I see this used e.g. as:
printk("%WiB", somevalue)
right? hmm, what if somevalue is say 5? If I understand correctly the
output then is: "5 iB".

I think the kernel documents all available formats in a single place.
(Is that here in barebox? If yes, please add your new formats here,

"5 iB" looks ugly, doesn't it? Do you care enough to fix that?

Hi,
this version 2
update the vsprintf by managing the iB internally and the Space
before the unit as optional
the others comments was also fix
The following changes since commit 0d35c3c8a0c2a1f1ff06eac20a12af0186753bc4:
menu: simplify usage for clients (2010-08-30 21:06:02 +0200)
are available in the git repository at:
git://git.jcrosoft.org/barebox.git sh-prepare
Jean-Christophe PLAGNIOL-VILLARD (9):
types.h: move __kernel_dev_t to include/linux/types.h
device: fix dev_name
stm8815: fix the uart device clock match
arm: move clkdev to drivers/clk
vsprintf: add %w and %w support to print unit
at91/clock: switch to %w for clock info printing
cfi_flash: use %W and IEEE 1541 format
use %W instead of size_human_readable and use IEEE 1541 format
clkdev: add print clk info command

dev_name is supposed to return the name of the device plus the id
currently we use %s%d format where in the kernel the use %s.%d
we may think to switch to this format for the device name and keeping the %s%d
for the devfs
this will be usefull to not modify the clock device name as example

as refer in this patch "arm & sh: factorised duplicated clkdev.c"
factorise some generic infrastructure to assist looking up struct clks
for the ARM & SH architecture.
as the code is identical at 99% in linux
move it also as preparing for the SH adding

To: barebox
Show a '%w' or %W thing. This will show a unit
at format xxx[.xxx][ ][ kMG] with iEEE 1541 support
The precision can not excess the base kMG of the current unit
otherwise it will be automatically reduce
If no precision is specified and there is rest we will use a default
precision of 3 as 66.667 M or 66.667M
%#w or %#W will add a space between the value and the unit
The base will be typically 1000 for Hz or B and 1024 for iB
for 1024 the i is automactically add for val >= 1024

Something like: %lWuB to print an unsigned long using the ieee format
