Existing boards by default have an issue where the LBC SDRAM
SPD EEPROM and the DDR2 SDRAM SPD EEPROM both land at 0x51.
After the hardware modification listed in the README is made,
then the DDR2 SPD EEPROM appears at 0x53. So this implements
a board specific get_spd() by taking advantage of the existing
weak linkage, that 1st tries reading at 0x53 and then if that
fails, it falls back to the old 0x51.
Since the old dependency issue of "SPD implies no LBC SDRAM"
gets removed with the hardware errata fix, remove that restriction
in the code, so both LBC SDRAM and SPD can be selected.

Previously, SPD configuration of RAM was non functional on
this board. Now that the root cause is known (an i2c address
conflict), there is a simple end-user workaround - remove the
old slower local bus 128MB module and then SPD detection on the
main DDR2 memory module works fine.
We make the enablement of the LBC SDRAM support conditional on
being not SPD enabled. We can revisit this dependency as the
hardware workaround becomes available.
Turning off LBC SDRAM support revealed a couple implict dependencies
in the tlb/law code that always expected an LBC SDRAM address.
This has been tested with the default 256MB module, a 512MB
a 1GB and a 2GB, of varying speeds, and the SPD autoconfiguration
worked fine in all cases.
The default configuration remains to go with the hard coded
DDR config, so the default build will continue to work on boards
where people don't bother to read the docs. But the advantage
of going to the SPD config is that even the small default module
gets configured for CL3 instead of CL4.

These were cloned from the mpc8548cds platform which has
a different memory layout (1/2 the size). Set the values
by comparing to the register file for the board used during
JTAG init sequence:
LSDMR1 0x2863B727 /* PCHALL */
LSDMR2 0x0863B727 /* NORMAL */
LSDMR3 0x1863B727 /* MRW */
LSDMR4 0x4063B727 /* RFEN */
This differs from what was there already in that the RFEN is
not bundled in all four steps implicitly, but issued once
as the final step.
The other difference seen when comparing vs. the register file init,
is that since the memory is split across /CS3 and /CS4, the dummy
writes need to go to 0xf000_0000 _and_ to 0xf400_0000.
We also rewrite the final LBC SDRAM inits as macros, as there is
no real need for them to be a local variable that is modified
on the fly at runtime.

This board has an 8MB soldered on flash, and a 64MB SODIMM
flash module. Normally the board boots from the 8MB flash,
but the hardware can be configured for booting from the 64MB
flash as well by swapping CS0 and CS6. This can be handy
for recovery purposes, or for supporting u-boot and VxBoot
at the same time.
To support this in u-boot, we need to have different BR0/OR0
and BR6/OR6 settings in place for when the board is configured
in this way, and a different TEXT_BASE needs to be used due
to the larger sector size of the 64MB flash module.
We introduce the suffix _8M and _64M for the BR0/BR6 and the
OR0/OR6 values so it is clear which is being used to map what
specific device.
The larger sector size (512k) of the alternate flash needs
a larger malloc pool, otherwise you'll get failures when
running saveenv, so bump it up accordingly.

The current situation has the 64MB user flash at an awkward
alignment; shifted back from 0xfc00_0000 by 8M, to leave an 8MB hole
for the soldered on boot flash @ EOM. But to switch to optionally
supporting booting off the 64MB flash, the 64MB will then be mapped
at the sane address of 0xfc00_0000.
This leads to awkward things when programming the 64MB flash prior
to transitioning to it -- i.e. even though the chip spans from
0xfb80_0000 to 0xff7f_ffff, you would have to program a u-boot image
into the two sectors from 0xfbf0_0000 --> 0xfbff_ffff so that it was
in the right place when JP12/SW2.8 were switched to make the 64MB on
/CS0. (i.e. the chip is only looking at the bits in mask 0x3ff_ffff)
We also have to have three TLB entries responsible for dealing with
mapping the 64MB flash due to this 8MB of misalignment.
In the end, there is address space from 0xec00_0000 to 0xefff_ffff
where we can map it, and then the transition from booting from one
config to the other will be a simple 0xec --> 0xfc mapping. Plus we
can toss out a TLB entry.
Note that TLB0 is kept at 64MB and not shrunk down to the 8MB boot
flash; this means we won't have to change it when the alternate
config uses the full 64MB for booting, in TLB0.

This reverts commit ccf1ad535a.
The commit "SBC8548: fix address mask to allow 64M flash"
essentially made this change:
* OR6:
- * Addr Mask = 64M = OR6[0:16] = 1111 1100 0000 0000 0
+ * Addr Mask = 64M = OR6[0:16] = 1111 1000 0000 0000 0
But this makes no sense, as section 13.3.1.2.1 in the
MPC8548ERM v2 clearly indicates the masks:
1111_1111_1000_0000_0 8 Mbytes
1111_1100_0000_0000_0 64 Mbytes
1111_1000_0000_0000_0 128 Mbytes
So the original value was correct, and the commit was invalid,
causing a 128MB mapping for a 64MB flash device. The problem
rears its head when trying to configure u-boot to have access
to both flash, since the default memory map is:
FB80_0000 – FF7F_FFFF 32-bits 64MB FLASH SODIMM
FF80_0000 – FFFF_FFFF 8-bits 8MB FLASH
By extending the mapping of the 64MB flash to 128MB, it now
conflicts with the normal 8MB boot flash, causing issues.

This EEPROM is hardware-write-protected and used to persist key
information such as the serial number and MAC addresses even if the
primary environment sector in NOR FLASH is overwritten.
During manufacturing, the environment is initialized from Linux and then
the key parameters copied to the EEPROM via U-Boot:
env export -c -s 0x2000 $loadaddr serial# macaddr mac1addr mac2addr
eeprom write $loadaddr 0x0000 0x2000
The chip is then locked via hardware for delivery.
When doing a field U-Boot upgrade, the environment is erased and reset
to the defaults to avoid problems with "hwconfig" changes, etc. After
loading the new U-Boot image, the hardware data is reloaded:
i2c dev 0
eeprom read $loadaddr 0x0000 0x2000
env import -c $loadaddr 0x2000
saveenv
The first three commands are saved in the "restore_eeprom" variable for
user convenience. (EG: "run restore_eeprom && saveenv")

Most of the ethernet connections are internal links with specialized
hardware and are not useful for "dhcp" or general-purpose networking;
U-Boot should not be cycling through them. Force the primary external
network interface in "ethprime" and disable the interface cycling with
"ethrotate=no".
Additionally, the environment variable "preboot" has its own config
option and means something entirely different from what the HWW-1U-1A
variable was intended for. Rename the board variable to "setbootargs"
to avoid potential confusion.
Finally, fix an incorrect address for the kernel in FLASH memory.
