9f530d59e6 e300: increase CONFIG_SYS_BOOTMAPSZ to allow booting large kernels
Newer Linux kernels can overrun the initial memory window used for
booting with their BSS area. When this happens, they overwrite the FDT
and silently fail to boot.

On e300 CPUs, the Linux kernel uses an initial BAT covering the first
256MB of RAM. See arch/powerpc/kernel/head_32.S for details. Increase
the value of CONFIG_SYS_BOOTMAPSZ to accommodate the maximum value
allowed by Linux. This will allow very large kernels to boot.

24956642ef Remove unused CONFIG_SERIAL_SOFTWARE_FIFO feature
This patch removes the completely unused CONFIG_SERIAL_SOFTWARE_FIFO
feature from U-Boot. It has only been implemented for PPC4xx and was not
used at all. So let's remove it and make the code smaller and cleaner.

582c55a027 83xx, uec: split enet_interface in two variables
There's no sensible reason to unite speed and interface type into
one variable.  So split this variable enet_interface into two
vars: enet_interface_type, which hold the interface type and speed.

Also: add the possibility for switching between 10 and 100 MBit
interfaces on the fly, when running in FAST_ETH mode.

c7190f028f mpc83xx: retain POR values of non-configured ACR, SPCR, SCCR, and LCRR bitfields
some LCRR bits are not documented throughout the 83xx family RMs.
New board porters copying similar board configurations might omit
setting e.g., DBYP since it was not documented in their SoC's RM.

Prevent them bricking their board by retaining power on reset values
in bit fields that the board porter doesn't explicitly configure
via CONFIG_SYS_<registername>_<bitfield> assignments in the board
config file.

also move LCRR assignment to cpu_init_r[am] to help ensure no
transactions are being executed via the local bus while CLKDIV is being
modified.

also start to use i/o accessors.

39df00d9ae i2c, mpc83xx: add CONFIG_SYS_I2C_INIT_BOARD for fsl_i2c
This patch adds the possibility to call a board specific
i2c bus reset routine for the fsl_i2c bus driver, and adds
this option for the keymile kmeter1 board.

The deblock sequence for this board is implemented and
tested in the following way:

CR = 0x20 (release SDA and SCL pin)
CR = 0xa0 (start read)
dummy read
dummy read
if 2. dummy read == 0x00
	3. dummy read

CR = 0x80 (SDA and SCL now 1 SR = 0x86)
CR = 0x00 (Modul reset SR=0x81)
CR = 0x80 (SDA and SCL = 1, SR = 0x81)

dc71b248ef powerpc: updates for the keymile boards
- CONFIG_SYS_MAX_I2C_BUS changed to 1
  We use only one I2C hardwarecontroller on this boards, so
  change the CONFIG_SYS_MAX_I2C_BUS to 1.
- common: dont print errormsg if second IVM Block lacks.
- 82xx, mgcoge: fix double mtdpart entry in environment
- 82xx, mgcoge: activate on second Flash the second bank.
- common: CONFIG_ENV_SIZE 0x4000 for all keymile boards
- common: Change malloc size to 1MByte for all Keymile boards
    We need a bigger malloc area for the environment support (128k)
    on some Keymile boards (kmeter1) and the upcoming UBI support.
    Change it to 1MB for all Keymile boards to be on the save side.
    Also define CONFIG_SYS_64BIT_VSPRINTF which is needed for
    UBI/UBIFS support.
- Add UBI support to all Keymile boards
- change manner of writing "/localbus/ranges" node
    instead of writting the complete "/localbus/ranges" node
    before booting Linux, only update the ranges entries
    which gets dynamical detected (size of flashes).
    This is needed, because keymile adds in the DTS
    "/localbus/ranges" node entries, which u-boot must
    not overwrite/delete.
- kmeter, mgcoge: define 2 seperate regions needed for the Intel P30 chips
    The Intel P30 chip has 2 non-identical chips on
    one die, so we need to define 2 seperate regions
    that are scanned by physmap_of independantly.
- kmeter1: Add MTD concat support to Keymile boards
- 82xx, mgcoge: add "unlock=yes" to default environment
- added CONFIG_MTD_DEVICE to get in sync with mainline code
