The BCSR17[7] = 1 will unlock the write protect of FLASH.
The WP# pin only controls the write protect of top/bottom sector,
That is why we can save env, but we can't write the first sector
before the patch.

This patch fixes MDIO clock setup in case when OPB frequency is 100MHz.
Current code assumes that the value of sysinfo.freqOPB is 100000000
when OPB frequency is 100MHz. In reality it is 100000001. As a result
MDIO clock is set to incorrect value, larger than 2.5MHz, thus violating
the standard. This in not a problem on boards equipped with Marvell PHYs
(e.g. Canyonlands), since those PHYs support MDIO clocks up to 8.3MHz,
but can be a problem for other PHYs (e.g. Realtek ones).

In GMII mode (which operates at 3.3V) both SICRH TSEC1/2 output buffer
impedance bits should be clear, i.e., SICRH[TSIOB1] = 0 and SICRH[TSIOB2] = 0.
SICRH[TSIOB1] was erroneously being set high.
U-Boot always operated this PHY interface in GMII mode. It is assumed this
was missed in the clean up by the original board porters, and copied along

Several boards used different ways to specify the size of the
protected area when enabling flash write protection for the sectors
holding the environment variables: some used CONFIG_ENV_SIZE and
CONFIG_ENV_SIZE_REDUND, some used CONFIG_ENV_SECT_SIZE, and some even
a mix of both for the "normal" and the "redundant" areas.
Normally, this makes no difference at all. However, things are
different when you have to deal with boards that can come with
different types of flash chips, which may have different sector
sizes.
Here we may have to chose CONFIG_ENV_SECT_SIZE such that it fits the
biggest sector size, which may include several sectors on boards using
the smaller sector flash types. In such a case, using CONFIG_ENV_SIZE
or CONFIG_ENV_SIZE_REDUND to enable the protection may lead to the
case that only the first of these sectors get protected, while the
following ones aren't.
This is no real problem, but it can be confusing for the user -
especially on boards that use CONFIG_ENV_SECT_SIZE to protect the
"normal" areas, while using CONFIG_ENV_SIZE_REDUND for the
"redundant" area.
To avoid such inconsistencies, I changed all sucn boards that I found
to consistently use CONFIG_ENV_SECT_SIZE for protection. This should
not cause any functional changes to the code.

The mmc code defines the response as an array of chars. However, it
access the response bytes both as (i) an array of four uints (with
casts) and (ii) as individual chars. The former case is used more
often, including by the driver when it assigns the response.
The char-wise accesses are broken on little endian systems because they
assume that the bytes in the uints are in big endian byte order.
This patch fixes this by changing the response to be an array of four
uints and replacing the char-wise accesses with equivalent uint-wise
accesses.

Currently using JFFS2 with MTDPARTS enabled doesn't work. This is because
mtdparts_init() is available in both files, cmd_mtdparts.c and
cmd_jffs2.c. Please note that in the original cmd_jffs2.c file (before
the jffs2/mtdparts command/file split those 2 different versions
already existed. So this is nothing new. The main problem is that the
variables "current_dev" and "current_partnum" are declared in both
files now. This doesn't work.
This patch now changes the names of those variable to more specific
names: "current_mtd_dev" and "current_mtd_partnum". This is because
this patch also changes the declaration from static to global, so
that they can be used from both files.
Please note that my first tests were not successful. The MTD devices
selected via mtdparts are now accessed but I'm failing to see the
directory listed via the "ls" command. Nothing is displayed. Perhaps
I didn't generate the JFFS2 image correctly (I never used JFFS2 in
U-Boot before). Not sure. Perhaps somebody else could take a look at
this as well. I'll continue looking into this on Monday.

The timer_reset() function would reset the timestamp, but not the actual

Commit 574b319512 introduced a subtle bug by mixing a list of tests
for "dev_desc->type" and "dev_desc->if_type" into one switch(), which
then mostly did not work because "dev_desc->type" cannot take any
"IF_*" type values. A later fix in commit 8ec6e332ea changed the
switch() into testing "dev_desc->if_type", but at this point the
initial test for unknown device types was completely lost, which
resulted in output like that for IDE ports without device attached:
Device 1: Model: Firm: Ser#:
Type: # 1F #
Capacity: not available
This patch re-introduces the missing test for unknown device types.

cpu/mpc8260/cpu.c used to use do_fixup_by_path_u32() to update the

"/cpus/OF_CPU", with OF_CPU beind defined in the board config file.
However, this does not work when one board config file (here:
MPC8260ADS.h) is intended to be used for several diffrent CPUs and
therefor contains a generic definition like "cpu@0", as the device
trees that will then be loaded will contain specific names like
"PowerPC,8272@0".
We switch to using do_fixup_by_prop_u32() instead, so we can search
for device_type="cpu", as it is done in other architectures, too.
