After determining how much DDR is actually in the system, set DBAT0 and
IBAT0 accordingly. This ensures that the CPU won't attempt to access
(via speculation) addresses outside of actual memory.
On 86xx systems, DBAT0 and IBAT0 (the BATs for DDR) are initialized to 2GB
and kept that way. If the system has less than 2GB of memory (typical for
an MPC8610 HPCD), the CPU may attempt to access this memory during
speculation. The zlib code is notorious for generating such memory reads,
and indeed on the MPC8610, uncompressing the Linux kernel causes a machine
check (without this patch).
Currently we are limited to power of two sized DDR since we only use a
single bat. If a non-power of two size is used that is less than
CONFIG_MAX_MEM_MAPPED u-boot will crash.

Use the same code between primary and secondary cores to init the
L1 cache. We were not enabling cache parity on the secondary cores.
Also, reworked the L1 cache init code to match the e500mc L2 init code
that first invalidates the cache and locks. Than enables the cache and
makes sure its enabled before continuing.

This patch fixes a problem introduced with patch eb5eb2b0
[ppc4xx: Cleanup PPC4xx I2C infrastructure]. We need to assign the I2C
base address to the "i2c" pointer inside of the controller loop.
Otherwise controller 0 is initialized multiple times instead of
initializing each I2C controller sequentially.

440EPx fixed bootstrap options A, B, D, and E sets PLL FWDVA to a value = 1.
This results in the PLLOUTB being greater than the CPU clock frequency

This patch reprograms the FWDVA satisfying the requirement of setting FWDVB

If a board uses cfb_console driver and splash image
and also defines CONFIG_SILENT_CONSOLE, the user is
locked out even if "silent" is not set. It is not
possible to get any output, neither on vga console
device nor on serial console after redirecting the
output to the serial console, since the GD_FLG_SILENT
flag remains set.
Fix the problem by redirecting the output from frame
buffer to serial console if splashimage is used.
Only suppress the output if "silent" environment
variable was set and don't set the GD_FLG_SILENT
flag arbitrarily.

So far, TFTP negotiated a fixed retransmission timeout of 5 seconds.
In some cases (busy networks, slow TFTP servers) this caused very
slow transfers. A new environment variable "tftptimeout" allows to
set this timeout. Lowering this value may make downloads succeed
faster in networks with high packet loss rates or with unreliable
TFTP servers.

The auto-update feature (CONFIG_UPDATE_TFTP) requires that the env
variable serverip be set for the TFTP access. If DHCP is to be used
to get the serverip env variable, this doesn't work as DHCP happens
after the auto-update attempt has run. A solution is to run DHCP in
PREBOOT, but even this is too late.
