Now that the mtd core supports more then 64 ecc bytes we can use it instead of
some a custom hack in the jz4740 nand driver.
This patch removes the custom {read,write}_page handlers from the jz4740 nand
driver. Thus the driver will now fallback to the default handlers from the nand
core.

The "kgdb_connected" variable of debug_core just indicates whether or

prevent a script from trying invoke kgdbts again and possibly crashing
the system (see Call Trace below).
The configured variable in kgtbts can be used instead of
kgdb_connected instead of kgdb_connected. The cleanup_kgdbts() can
also be removed because there is no possible way to build kgdbts as a

The OCTEON II SOC has USB EHCI and OHCI controllers connected directly
to the internal I/O bus. This patch adds the necessary 'glue' logic
to allow ehci-hcd and ohci-hcd drivers to work on OCTEON II.
The OCTEON normally runs big-endian, and the ehci/ohci internal
registers have host endianness, so we need to select
USB_EHCI_BIG_ENDIAN_MMIO.
The ehci and ohci blocks share a common clocking and PHY
infrastructure. Initialization of the host controller and PHY clocks
is common between the two and is factored out into the
octeon2-common.c file.
Setting of USB_ARCH_HAS_OHCI and USB_ARCH_HAS_EHCI is done in
arch/mips/Kconfig in a following patch.
