get_cpu_board_revision() returned board revision based on information stored
in global static struct eeprom. It should instead use one from local struct
board_eeprom, to which the data is actually read from EEPROM. The bug led to
system hang after printing L1 cache information on U-Boot startup. The problem
was observed on MPC8555CDS system and possibly affects other Freescale MPC85xx
boards using CFG_I2C_EEPROM_CCID.
The change has been successfully tested on MPC8555CDS system.

Commit 2a1a2cb6 didnt remove the dummy mem reservation in fdt_chosen,
and this stopped Linux from booting with a Ramdisk. This patch fixes
this, by deleting the useless dummy mem reservation.
When booting with a Ramdisk, a fix offset FDT_RAMDISK_OVERHEAD is now
added to of_size, so we dont need anymore a dummy mem reservation.
I measured the value of FDT_RAMDISK_OVERHEAD on a MPC8270 based
system (=0x44 bytes) and rounded it up to 0x80).

This patch implements support for flash-based BBT for chips working
through ELBC NAND controller, so that NAND core will not have to re-scan
for bad blocks on every boot.
Because ELBC controller may provide HW-generated ECCs we should adjust
bbt pattern and bbt version positions in the OOB free area.

For large page chips, nand_bbt is looking into OOB area, and checking
for "0xff 0xff" pattern at OOB offset 0. That is, two bytes should be
reserved for bbt means.
But ELBC driver is specifying ecclayout so that oobfree area starts at
offset 1, so only one byte left for the bbt purposes.
This causes problems with any OOB users, namely JFFS2: after first mount
JFFS2 will fill all OOBs with "erased marker", so OOBs will contain:
OOB Data: ff 19 85 20 03 00 ff ff ff 00 00 08 ff ff ff ff
OOB Data: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
OOB Data: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
OOB Data: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
And on the next boot, NAND core will rescan for bad blocks, then will
see "0xff 0x19" pattern, and will mark all blocks as bad ones.
To fix the issue we should implement our own bad block pattern: just one
byte at OOB start. Though, this will work only for x8 chips. For x16
chips two bytes must be checked. Since ELBC driver does not support x16
NANDs (yet), we're safe for now.
