This patch undoes the patch by Jeff Mann with commit-id ada4697d. As
suggested by AMCC it is not recommended to dynamically change the EBC
speed after bootup. So we undo this change to be on the safe side.

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.

The U-Boot NAND booting support is now extended to support ECC
upon loading of the NAND U-Boot image.
Tested on AMCC Sequoia (440EPx) and Bamboo (440EP).

This patch updates the "normal" Bamboo NOR booting port, so
that it is compatible with the coming soon NAND booting
Bamboo port.
It also enables the 2nd NAND flash on the Bamboo.

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.

This patch updates the nand_ecc code to the latest Linux version.
The main reason for this is the more compact code. This makes
it possible to include the ECC code into the NAND bootloader
image (NAND_SPL) for PPC4xx.

Allow passing longer command line to the kernel - useful especially

Change EEPROM configuration according to the datasheet: "The 24C01A and 24C02A
have a page write capability of two bytes", and "This device offers fast (1ms)
byte write". Add 3ms of extra delay.

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
008861a2f3ef2c062744d733787c7e530a1b8761, 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.

This patch updates the Acadia (405EZ) support for the new 1.1 board
revision. It also adds support for NAND FLASH via the 4xx NDFC.
Please note that the jumper J7 must be in position 2-3 for this
NAND support. Position 1-2 is for NAND booting only. NAND booting
support will follow later.

Because the Sequoia board does not boot with an EBC faster than 66MHz,
the clock divider are changed after the initial boot process.
This allows for maximum clocking speeds to be achieved on newer boards.
Sequoia boards with 666.66 MHz processors require that the EBC divider
be set to 3 in order to start the initial boot process at a slower EBC
speed. After the initial boot process, the divider can be set back to 2,
which will cause the boards to run at 83.333MHz. This is backward
compatible with boards with 533.33 MHz processors, as these boards will
already be set with an EBC divider of 2.
