1aaab9bfae Make scripts and Makefiles POSIX compliant
The bash builtin versions of the "test" (resp. "[") command allow
using "==" for string comparisons, but POSIX compatible implemen-
tations (like /usr/bin/test) insist on using "=" only. On such systems
you will see:

	$ /usr/bin/test a == a && echo OK
	/usr/bin/test: ==: binary operator expected

This patch fixes Makefiles and scripts to use POSIX style.

c05569066d ppc4xx: Enable 405EP PCI arbiter per default on all boards
In an attmemt to clean up the 4xx start.S file, I removed the enabling
of the internal 405EP PCI arbiter. This is needed for multiple other
405EP platforms, like most of the esd 405EP. Now the internal PCI
arbiter is enabled again per default as it has been before.

aba19604d8 Add 440EPx DDR2 SPD DIMM support
This patch adds SPD DDR2 support for the 440EPx ("Denali") SDRAM
controller.  It should also work on the 440GRx.  It is based on the DDR2
SPD code for the 440EP/440EPx, but makes no provision for DDR1 support.

This code has been tested on prototype Korat boards with three Kingston
DIMMS: 512 MiB ECC (one rank), 512 MiB non-ECC (one rank) and 1 GiB ECC
(two ranks).  The Korat board has a single DIMM socket, but support has
been provided (though not tested) for boards with two DIMM sockets.

1261827868 Add driver for STMicroelectronics M41T60 RTC
This driver is based on the driver for the M41T11.  In the intended
application, the RTC will be powered by a large capacitor, rather than a
battery.  The driver therefore checks to see whether the RTC has lost
power.  The chip's OUT bit is normally reset from its power-up state.  If
the OUT bit is read as set, or if the date and time are not valid, then the
RTC is assumed to have lost power, and its date and time are reset to
1900-01-01 00:00:00.

Support for adjusting the speed of the clock to improve accuracy is
provided through an environment variable.

d91722102c ppc4xx: Fix problem in 44x cache POST routine
As repoted by Larry Johnson, running "diag run cache" caused a crash
in U-Boot. This problem was introduced by a patch that removed the
TLB entry for the cache test after the test has completed. Since this
TLB was only setup once, a 2nd attempt to run this cache test
failed with a crash. Now this TLB entry is created every time the
routine is called.
