Previous code was failing when reading back the timer less than
400us after resetting it. This lead nand operations to incorrectly
timeout any now and then. Moreover, writing the load register isn't
immediately reflected in the value register. We must wait for a clock
edge, so read_timer now waits for the value to change at least once,
otherwise nand operation would timeout anyways (though less frequently).

As per coding guidlines, it is good to maintain proper ordering

This was missed during initial coding, corrected here.

According to the PPC reference implementation the udelay() function is
responsible for resetting the watchdog timer as frequently as needed.
Most other architectures do not meet that requirement, so long-running
operations might result in a watchdog reset.
This patch adds a generic udelay() function which takes care of
resetting the watchdog before calling an architecture-specific
__udelay().

U-boot for Marvell Kirkwood boards no longer work after the EABI changes
introduced in commit f772acf8a584067033eff1e231fcd1fb3a00d3d9. This
turns out to be caused by a stack alignment issue. The armv5te
instructions ldrd/strd instructions require 8-byte alignment to work
properly (otherwise undefined behavior).
Tested on an OpenRD base board, where both printouts and ubifs stuff now
works.

This feature can be used to trigger special command "sysrstcmd" using
reset key long press event and environment variable "sysrstdelay" is set
(useful for reset to factory or manufacturing mode execution)
Kirkwood SoC implements a hardware-based SYSRSTn duration counter.
When SYSRSTn is asserted low, a SYSRSTn duration counter is running.
The counter value is stored in the SYSRSTn Length Counter Register
The counter is based on the 25-MHz reference clock (40ns)
It is a 29-bit counter, yielding a maximum counting duration of
2^29/25 MHz (21.4 seconds). When the counter reach its maximum value,
it remains at this value until counter reset is triggered by setting
bit 31 of KW_REG_SYSRST_CNT
Implementation:
Upon long reset assertion (> ${sysrstdelay} in secs) sysrstcmd will be
executed if pre-defined in environment variables.
This feature will be disabled if "sysrstdelay" variable is unset.
for-ex.
setenv sysrst_cmd "echo starting factory reset;
nand erase 0xa0000 0x20000;
echo finish ed sysrst command;"
will erase particular nand sector if triggered by this event

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.

Commit 70ebf316 factored out the ROUND() macro into include/common.h,
not realizing that the primary use of this macro on AT91 systems was
in start.S where common.h was not included, and could not be included
because it contains a lot of C code which the assembler doesn't
understand.
This patch wraps such code in common.h in a "#ifndef __ASSEMBLY__"
construct, and then adds an include to cpu/arm926ejs/start.S thus
solving the problem.

timer code, which is now both correct and much smaller. Unused
functions like udelay_masked() have been removed as no driver uses
them, even the ones that are not currently active for this board.
