Fix memory initialization on MPC8349E-mITX
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.

mpc83xx: Change PVR_83xx to PVR_E300C1-3, and update checkcpu().

prints the core that it detects, rather than aborting if it doesn't find

Fix serious pointer bug with bootm and reserve map.
What was suppose to be a stack variable was declared as a pointer,
overwriting random memory.
Also moved the libfdt.a requirement into the main Makefile. That is
The U-Boot Way.
Use "setter" functions instead of flags, cleaner and more flexible.
It also fixes the problem noted by Timur Tabi that the ethernet MAC
addresses were all being set incorrectly to the same MAC address.
In bootm, create the "/chosen" node only if it doesn't already exist
(better matches the previous behavior).
Update for proper reserved memory map handling for initrd.
Driver for the Atmel MACB on-chip ethernet controller.
This driver has been tested on the ATSTK1000 board with a AT32AP7000
CPU. It should probably work on AT91SAM926x as well with some minor
modifications.
Hardware documentation can be found in the AT32AP7000 data sheet,
which can be downloaded from
AVR32: Add clk and gpio infrastructure for macb0 and macb1
Implement functions for configuring the macb0 and macb1 pins, as
well as functions for getting the clock rate of the various
busses the macb ethernet controllers are connected to.
Include the imi, imls and jffs commands sets by default on ATSTK1000.
Also define CONFIG_BOOTARGS to something more useful, define
CONFIG_BOOTCOMMAND and enable autoboot by default.
AVR32: Use initdram() instead of board_init_memories()
Conform to the "standard" interface and use initdram() instead of
board_init_memories() on AVR32. This enables us to get rid of the
sdram_size member of the global_data struct as well.
Rewrite the resource management code (i.e. I/O memory, clock gating,
gpio) so it doesn't depend on any global state. This is necessary
because this code is heavily used before relocation to RAM, so we
can't write to any global variables.
As an added bonus, this makes u-boot's memory footprint a bit smaller,
although some functionality has been left out; all clocks are enabled
all the time, and there's no checking for gpio line conflicts.
Add -fPIC -mno-init-got to the avr32-specific CFLAGS to make u-boot
position independent. This will make relocation a lot easier.
-mno-init-got means that gcc shouldn't emit code to load the GOT
address into r6 in every function prologue. We do it once and for
all in the early startup assembly code, so enabling this option
makes u-boot a bit faster and smaller.
The assembly parts have always been position-independent, so no code
changes should be necessary.
AVR32: Split start_u_boot into board_init_f and board_init_r
Split the avr32 initialization code into a function to run before
relocation, board_init_f and a function to run after relocation,
board_init_r. For now, board_init_f simply calls board_init_r
at the end.
