86xx: Support 2GB DIMMs
Configure the number of bits used to address the banks inside the SDRAM

Higher capacity devices like a 2GB DIMM require 3 bits to address 8 banks.

fix easylogo on big endian dev systems
didnt realize how out of shape easylogo actually was until i tried using it.
this patch does byte swapping as need be on the input tga header since the tga
is in little endian but the host could just as well be big endian. i didnt
bother using bswap macros or such stuff from system headers as nothing in
POSIX dictates byte swapping functionality.
This patch allows u-boot to build without error in a cygwin
environment. Cygwin does not define __u64 in it's
include/asm/types.h file. The -idirafter flag in the u-boot
build causes the inclusion of the cygwin types.h file as opposed
to u-bot/include/asm/types.h file which does define __u64.
Subsequently, sha1.c compile fails due to unknown symbol.

Fix and optimize MII operations on FEC (MPC8xx) controllers
This patch fixes several issues at least on a MPC885 based system with two
FEC interfaces used in MII mode.
1. PHY discovery should first read PHY_PHYIDR2 register and only then
PHY_PHYIDR1 like cpu/mpc8xx/fec.c::mii_discover_phy() does it,
otherwise the values read are wrong. Also notice, that PHY discovery
cannot work on MPC88x / MPC87x in setups with both FECs active at all
in its present form, because for both interfaces the registers from FEC
1 are used to communicate over MII.
2. Remove code duplication for resetting the FEC by isolating it into a
separate function.
3. Initialize MII on FEC 1 when communicating over FEC 2 in fec_init().
4. Optimize mii_init() to only reset the FEC 1 controller once.
5. Fix a typo in mii_init() using index i instead of j thus potentially
leading to unpredictable results.
It is unclear on what platforms this driver has been tested, since
noone up to now defines CONFIG_RTL8169 in the board configuration
header. Now it has been fixed for a big-endian mpc8241 based
linkstation platform. This patch presents the necessary endianness
conversion fixes.

POST: Execute SPR test after relocation
On LWMON5 we now use d-cache as init-ram and stack. The SPR POST test uses
self modifying code and this doesn't work with stack in d-cache, since
I can't move the code from d-cache to i-cache. We move the SPR test to
be executed a little later, after relocation. Then stack is located in
SDRAM and this self-modifying code is no problem anymore.

ppc4xx: Update Katmai/44x_spd_ddr2.c code for optimal DDR2 setup
On Katmai the complete auto-calibration somehow doesn't seem to
produce the best results, meaning optimal values for RQFD/RFFD.
This was discovered by GDA using a high bandwidth scope,
analyzing the DDR2 signals. GDA provided a fixed value for RQFD,
so now on Katmai "only" RFFD is auto-calibrated.
This patch also adds RDCC calibration as mentioned on page 7 of
the AMCC PowerPC440SP/SPe DDR2 application note:
"DDR1/DDR2 Initialization Sequence and Dynamic Tuning"
First, it adds function gpio_read_in_bit() to read the a bit from the
GPIO Input Register (GPIOx_IR) in the same way that function
gpio_read_out_bit() reads a bit from the GPIO Output Register
(GPIOx_OR).
Second, it modifies function gpio_set_chip_configuration() to provide
an additional option for configuring the GPIO from the
"CFG_4xx_GPIO_TABLE".
According to the 440EPx User's Manual, when an alternate output is used,
the three-state control is configured in one of two ways, depending on
the particular output. The first option is to select the corresponding
alternate three-state control in the GPIOx_TRSH/L registers. The second
option is to select the GPIO Three-State Control Register (GPIOx_TCR) in
the GPIOx_TRSH/L registers, and set the corresponding bit in the
GPIOx_TCR register to enable the output. For example, the Manual
specifies configuring the GPIO00 Alternate 1 Signal (PreAddr07) to use
the alternate three-state control (first option), and specifies
configuring the GPIO32 Alternate 1 Signal (USB2OM0) with the output
enabled in the GPIOx_TCR register (second option).
Currently, gpio_set_chip_configuration() configures all alternate signal
outputs to use the first option. This patch allow the second option to
be selected by setting the "out_val" element in the table entry to
"GPIO_OUT_1". The first option is used when the "out_val" element is
set to "GPIO_OUT_0". Because "out_val" is not currently used when an
alternate signal is selected, and because all current GPIO tables set
"out_val" to "GPIO_OUT_0" for all alternate signals, this patch should
not change any existing configurations.
