The latest changes showed a problem with the location of the NAND-SPL
image in the OCM and the init-data area (incl. cache). This patch
fixes this problem.

- Introduced dedicated switches for building 440 and 405 images required
for 440-specific machine instructions like 'rfmci' etc.
- Exception vectors moved to the proper location (_start moved away from
the critical exception handler space, which it occupied)
- CriticalInput now serviced (with default handler)
- MachineCheck properly serviced (added a dedicated handler and return
subroutine)
- Overall cleanup of exceptions declared with STD_EXCEPTION macro (unused,
unhandled and those not relevant for 4xx were eliminated)
- Eliminated Linux leftovers, removed dead code

Now program_tlb() allows to program a TLB (or multiple) with
different virtual and physical addresses. With this change, now one
physical region (e.g. SDRAM) can be mapped 2 times, once with caches
diabled and once with caches enabled.

This patch adds NAND booting support for the AMCC Acadia eval board.
Please make sure to configure jumper J7 to position 2-3 when booting
from NOR, and to position 1-2 when booting for NAND.
I also added a board command to configure the I2C bootstrap EEPROM
values. Right now only 267MHz is support for booting either via NOR
or NAND FLASH. Here the usage:
=> bootstrap 267 nor ;to configure the board for 267MHz NOR booting
=> bootstrap 267 nand ;to configure the board for 267MHz NNAND booting

This patch adds NAND booting support for the AMCC Bamboo eval board.
Since the NAND-SPL boot image is limited to 4kbytes, this version
only supports the onboard 64MBytes of DDR. The DIMM modules can't be
supported, since the setup code for I2C DIMM autodetection and
configuration is too big for this NAND bootloader.

This patch adds hardware ECC support to the NDFC driver. It also
changes the register access from using the "simple" in32/out32
functions to the in_be32/out_be32 functions, which make sure
that the access is correctly synced. This is the only recommended
access to SoC registers in the current Linux kernel.

After being reset in mpc5xxx_fec_init_phy(), PHY goes into FX mode, in which
networking does not function. This commit switches PHY to TX mode by clearing
the FX_SEL bit of Mode Control Register. It also reverses commit
008861a2f3, i.e., a temporary workaround.

Both CFG_PCISPEED_66 and CFG_IPBSPEED_133 are misnamed, as defining
them does not cause PCI or IPB clocks to run at the specified speed.
Instead, they configure divisors used to calculate said clocks. This
patch renames the defines according to their real function.

current PHY initalization code (tftp timeouts all the time). This commit
temporarily disables PHY initalization sequence to make the networking
operational, until a fix is found.
Some device trees have a mac-address property, some have local-mac-address,
and some have both. To support all of these device trees, ftp_cpu_setup()
should write the MAC address to mac-address and local-mac-address, if they
exist.

Define CFG_DDR_SDRAM_CLK_CNTL for the MPC8349E-mITX and MPC8349E-mITX-GP.
This allows ddr->sdram_clk_cntl to be properly initialized. This is necessary
on some ITX boards, notably those with a revision 3.1 CPU.
Also change spd_sdram() in cpu/mpc83xx/spd_sdram.c to not write anything into
ddr->sdram_clk_cntl if CFG_DDR_SDRAM_CLK_CNTL is not defined.
