Fix build warnings by putting specific used variables
under required #ifdefs for removing:
mem.c:227: warning: unused variable 'f_sec'
mem.c:226: warning: unused variable 'f_off'
mem.c:225: warning: unused variable 'size'
mem.c:224: warning: unused variable 'base'

v7_flush_dcache_all, because it depends on omap ROM code is not
generic. Rename the function to 'invalidate_dcache' and move it
to the omap cpu directory.
Collect the other omap cache routines l2_cache_enable and
l2_cache_disable with invalide_dcache into cache.S. This
means removing the old cache.c file that contained l2_cache_enable
and l2_cache_disable.
The conversion from cache.c to cache.S was done most through
disassembling the uboot binary. The only significant change was
to change the comparision for the return of get_cpu_rev from
cmp r0, #0
beq earlier_than_label
Which was lost information to
cmp r0, #CPU_3XX_ES20
blt earlier_than_label
The paths through the enable routine were verified by
adding an infinite loop and seeing the hang. Then
removing the infinite loop and seeing it continue.
The disable routine is similar enough that it was not
tested with this method.
Run tested by cold booting from nand on beagle and zoom1.
Compile tested on MAKEALL arm.

For some time there have been repeated reports about build problems
with some ARM (cross) tool chains. Especially issues about
(in)compatibility with the tool chain provided runtime support
library libgcc.a caused to add and support a private implementation
of such runtime support code in U-Boot. A closer look at the code
indicated that some of these issues are actually home-made. This
patch attempts to clean up some of the most obvious problems and make
building of U-Boot with different tool chains easier:
- Even though all ARM systems basicy used the same compiler options
to select a specific ABI from the tool chain, the code for this was
distributed over all cpu/*/config.mk files. We move this one level
up into lib_arm/config.mk instead.
- So far, we only checked if "-mapcs-32" was supported by the tool
chain; if yes, this was used, if not, "-mabi=apcs-gnu" was
selected, no matter if the tool chain actually understood this
option. There was no support for EABI conformant tool chains.
This patch implements the following logic:
1) If the tool chain supports
"-mabi=aapcs-linux -mno-thumb-interwork"
we use these options (EABI conformant tool chain).
2) Otherwise, we check first if
"-mapcs-32"
is supported, and then check for
"-mabi=apcs-gnu"
If one test succeeds, we use the first found option.
3) In case 2), we also test if "-mno-thumb-interwork", and use
this if the test succeeds. [For "-mabi=aapcs-linux" we set
"-mno-thumb-interwork" mandatorily.]
This way we use a similar logic for the compile options as the
Linux kernel does.
- Some EABI conformant tool chains cause external references to
utility functions like raise(); such functions are provided in the
new file lib_arm/eabi_compat.c
Note that lib_arm/config.mk gets parsed several times, so we must
make sure to add eabi_compat.o only once to the linker list.

Many of the help messages were not really helpful; for example, many
commands that take no arguments would not print a correct synopsis
line, but "No additional help available." which is not exactly wrong,
but not helpful either.
Commit ``Make "usage" messages more helpful.'' changed this
partially. But it also became clear that lots of "Usage" and "Help"
messages (fields "usage" and "help" in struct cmd_tbl_s respective)
were actually redundant.
This patch cleans this up - for example:
Before:
=> help dtt
dtt - Digital Thermometer and Thermostat
Usage:
dtt - Read temperature from digital thermometer and thermostat.
After:
=> help dtt
dtt - Read temperature from Digital Thermometer and Thermostat
Usage:
dtt

actually the timer init use the interrupt_init as init callback
which make the interrupt and timer implementation difficult to follow
so now rename it as int timer_init(void) and use interrupt_init for interrupt
btw also remane the corresponding file to the functionnality implemented
as ixp arch implement two timer - one based on interrupt - so all the timer
related code is moved to timer.c
