The board/freescale/m54418twr/config.mk defined TEXT_BASE, which has
the same value as CONFIG_SYS_TEXT_BASE.  The TEXT_BASE is referenced
by two files:
 - arch/m68k/cpu/mcf5445x/start.S and include/
 - include/configs/M54418TWR.h

Replace the references with CONFIG_SYS_TEXT_BASE and delete
board/freescale/m54418twr/config.mk.

For historical reason, CONFIG_SYS_TEXT_BASE has been specified
in various ways:

[1] by board/${VENDOR}/${BOARD}/config.mk

[2] by CONFIG_SYS_EXTRA_OPTIONS
    (This was "options" field of boards.cfg before Kconfig conversion)

[3] by include/configs/${BOARD}.h

[4] by configs/${BOARD}_defconfig

Most of M68K boards use either [1] or [2], both of which we want to
deprecate.  Switch them into [4], which is the newest way (Kconfig).

We still allow [3] too, because it is still used by many boards and
we expect much time for conversion.

ti-qspi driver currently uses 3-byte addressing mode(and opcodes) for

16MB.
Enable the 4-byte addressing(and use 4-byte opcode) for memory-mapped

On bootup the emmc's hw partition is always set to 0 and the partition
table is read from it. When switching to another hw partition the
partition table's id is not updated but instead the old one from
hw partition 0 is used. If there is no partition table on hw partition 0
then the code will terminate and return error even if the desired hw
partition contains a perfectly fine partition table. This fix updates
the partition table struct to correspond to the specified hw partition
before testing if the partition table is valid or not.

pci_virt_to_mem() uses virt_to_phys() to get the physical address.
But pci_virt_to_mem() is also called with uncached addresses which
is wrong according to the documentation of virt_to_phys().

Refactor the PCI_TO_MEM() macro to optionally map an uncached address
back to a cached one before calling pci_virt_to_mem().

Currently pcnet works because virt_to_phys() is incorrectly implemented
on MIPS. With the upcoming asm header file update for MIPS, the
virt_to_phys() implementation will be fixed. Thus this patch is needed
to keep pcnet working on MIPS Malta board.
