This patch renames NAND_MAX_CHIPS to CONFIG_SYS_NAND_MAX_CHIPS and
changes the default from 8 to 1 for the legacy and the new MTD
NAND layer. This allows to remove all NAND_MAX_CHIPS definitions
in the board config files because none of the boards use multi
chip support (NAND_MAX_CHIPS > 1) so far. The bamboo and the DU440
define
#define NAND_MAX_CHIPS CONFIG_SYS_MAX_NAND_DEVICE
but that's bogus and did not work anyhow.

Enable nand lock, unlock and status of lock feature.
Not every device and platform requires this, hence,
it is under define for CONFIG_CMD_NAND_LOCK_UNLOCK
Nand unlock and status operate on block boundary instead
of page boundary. Details in:

Rather than putting the function prototype for board_nand_init() in the one
place where it gets called, put it into nand.h so that every place that also
defines it gets the prototype. Otherwise, errors can go silently unnoticed
such as using the wrong return value (void rather than int) when defining
the function.

- Add subpage write support
- Add onenand_oob_64/32 ecclayout
This has been missing and without it UBI has some incompatibilies issues
with the current (>= 2.6.27) Linux kernel version. vid_hdr_offset is
placed differently (2048 instead of 512) without this fix.

The version (ver_id) was not stored in the onenand_chip structure and
because of this the continuous locking scheme could be enabled on some

The current code that determines which bank/chipselect is used for a
given NAND instance only worked for 32-bit addresses and assumed
a 1:1 mapping. This breaks in 36-bit physical configs.
The proper way to handle this is to use the virt_to_phys() and
BR_PHYS_ADDR() routinues to match the 34-bit lbc bus address
with the the virtual address the NAND code uses.

Initial support for NXP's 4 and 8 bit I2C gpio expanders
(eg pca9537, pca9557, etc). The CONFIG_PCA953X define
enables support for the devices while the CONFIG_CMD_PCA953X
define enables the pca953x command. The CONFIG_CMD_PCA953X_INFO
define enables an 'info' sub-command which provides summary
information for the given pca953x device.

All implementations of the functions i2c_reg_read() and
i2c_reg_write() are identical. We can save space and simplify the
code by converting these functions into inlines and putting them in

This patch tries to ensure that phy interrupt pin
won't be asserted after booting. We experienced
following issues with current 88E1121R phy init:
Marvell 88E1121R phy can be hardware-configured
to share MDC/MDIO and interrupt pins for both ports
P0 and P1 (e.g. as configured on socrates board).
Port 0 interrupt pin will be shared by both ports
in such configuration. After booting Linux and
configuring eth0 interface, port 0 phy interrupts
are enabled. After rebooting without proper eth0
interface shutdown port 0 phy interrupts remain
enabled so any change on port 0 (link status, etc.)
cause assertion of the interrupt. Now booting Linux
and configuring eth1 interface will cause permanent
phy interrupt storm as the registered phy 1 interrupt
handler doesn't acknowledge phy 0 interrupts. This
of course should be fixed in Linux driver too.

The current code will cause the creation of a 4GB window
starting at 0 if we have more than 4GB of RAM installed,
which overlaps with PCI_MEM space and causes pci_bus_to_phys()
to return erroneous information. Limit the size to 4GB - 1;
which causes the code to create one 2GB and one 1GB window
instead.

This patch defines all flash access functions as weak so that
they can be overridden by board specific versions.
This will be used by the upcoming VCTH board support where the NOR
FLASH unfortunately can't be accessed memory-mapped. Special
accessor functions are needed here.
To enable this weak functions you need to define
CONFIG_CFI_FLASH_USE_WEAK_ACCESSORS in your board config header.
Otherwise the "old" default functions will be used resulting
in smaller code.
