For MUSB devices that do not support multipoint (hubs), we have to emulate
a root hub so that we can support core operations like resetting ports.

In USB ehci driver, the port reset is not terminated. EHCI spec says "A host
controller must terminate the reset and stabilize the state of the port within
2 milliseconds". Without termination, a port stays at reset state. This is
observed on ppc4xx(sequoia) boards.

The RX Control/Status register has bits that we want to preserve, so don't
just write out a single bit. Preserve the others bits in the process.
The original code posted to the u-boot list had this behavior, but looks
like it was lost somewhere along the way to merging.

The dynamic FIFO handling under MUSB is optional, and some parts (like
the Blackfin processor) do not implement support for it.
Due to this, the FIFO reading/writing steps need special handling, so
mark the common versions weak so drivers can override.

Introduces various optimisations that approximately triple the

Most of these optimisations depend on the endianess of the machine

Moved the mdio regs out of the tsec structure,and
provided different offsets for tsec base and mdio
base so that provision for etsec2.0 can be provided.
This patch helps in providing the support for etsec2.0
In etsec2.0, the MDIO register space and the etsec reg
space are different.
Also, moved the TSEC_BASE_ADDR and MDIO_BASE_ADDR definitons into
platform specific files.

Davinci: NAND enable ECC even when not in NAND boot mode
On Davinci platforms, the default NAND device is enabled (for ECC)
in low level boot code when NAND boot mode is used. If booting in
another mode, NAND ECC is not enabled. The driver should make
sure ECC is enabled regardless of boot mode if NAND is configured
in U-Boot.

The header files usb.h and usbdescriptors.h have the same nameed
structure definitions for
usb_config_descriptor
usb_interface_descriptor
usb_endpoint_descriptor
usb_device_descriptor
usb_string_descriptor
These are out right duplicates in usb.h
usb_device_descriptor
usb_string_descriptor
This one has extra unused elements
usb_endpoint_descriptor
unsigned char bRefresh
unsigned char bSynchAddress;
These in usb.h have extra elements at the end of the usb 2.0
specified descriptor and are used.
usb_config_descriptor
usb_interface_descriptor
The change is to consolidate the definition of the descriptors
to usbdescriptors.h. The dublicates in usb.h are removed.
The extra element structure will have their name shorted by
removing the '_descriptor' suffix.
So
usb_config_descriptor -> usb_config
usb_interface_descriptor -> usb_interface
For these, the common descriptor elements are accessed now
by an element 'desc'.
As an example
- if (iface->bInterfaceClass != USB_CLASS_HUB)
+ if (iface->desc.bInterfaceClass != USB_CLASS_HUB)
This has been compile tested on MAKEALL arm, ppc and mips.

Depending on offset, flash size and the number of bad blocks,
get_len_incl_bad may return a too small value which may lead to:
1) If there are no bad blocks, nand_{read,write}_skip_bad chooses the
bad block aware read/write code. This may hurt performance, but does
not have any adverse effects.
2) If there are bad blocks, the nand_{read,write}_skip_bad may choose
the bad block unaware read/write code (if len_incl_bad == *length)
which leads to corrupted data.

This patch moves the s3c24x0 header files from include/ to
include/asm-arm/arch-s3c24x0/.
checkpatch.pl showed 2 errors and 3 warnings. The 2 errors were both due
to a non-UTF8 character in David M?ller's name:
ERROR: Invalid UTF-8, patch and commit message should be encoded in UTF-8
#489: FILE: include/asm-arm/arch-s3c24x0/s3c2410.h:3:
+ * David M?ller ELSOFT AG Switzerland. d.mueller@elsoft.ch
As David's name correctly contains a non-UTF8 character I haven't fixed
these errors.
The 3 warnings were all because of the use of 'volatile' in s3c24x0.h:
WARNING: Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt
#673: FILE: include/asm-arm/arch-s3c24x0/s3c24x0.h:35:
+typedef volatile u8 S3C24X0_REG8;
+typedef volatile u16 S3C24X0_REG16;
+typedef volatile u32 S3C24X0_REG32;
I'll fix these errors in another patch.
Tested by running MAKEALL for ARM8 targets and ensuring there were no new
errors or warnings.
