MIPS: start.S: use symbol __image_copy_end for U-Boot image relocation

Use the newly introduced symbol __image_copy_end as end address for
relocation of U-Boot image. This is needed for dynamic relocation added
in later patches. This patch obsoletes the symbols uboot_end and
uboot_end_data which are removed.

Get the start and end address for clearing BSS from the newly

addresses.

Also optimize the loop by moving the address incrementation
to the delay slot to avoid the initial sub instruction.

Saving the parameters in advance unnecessarily complicates

after the copy loop is done.

before calling flush_cache, and set the destination
address parameter in the delay slot of the actuall

The current code uses two instructions to load

This results in the following assembly code:

468: 3c088040 lui t0,0x8040
46c: 251d0000 addiu sp,t0,0

The first instuction loads the stack pointer into
the 't0' register then the value of the 'sp' register
is computed by adding zero to the value of the 't0'
register. The same issue present on the 64-bit version
as well:

into the 'sp' register. The generated code is functionally
equivalent to the previous version but it is simpler.

MIPS: start{, 64}.S: fill branch delay slots with NOP instructions

The romReserved and romExcHandle handlers are
accessed by a branch instruction however the
delay slots of those instructions are not filled.

Because the start.S uses the 'noreorder' directive,
the assembler will not fill the delay slots either,
and leads to the following assembly code:

0000056c <romReserved>:
56c: 1000ffff b 56c <romReserved>

00000570 <romExcHandle>:
570: 1000ffff b 570 <romExcHandle>

In the resulting code, the second branch instruction
is placed into the delay slot of the first branch
instruction, which is not allowed on the MIPS
architecture.

usb: use linux/usb/ch9.h instead of usbdescriptors.h

Linux usb/ch9.h seems to have all the same information (and more)
as usbdescriptors.h so use the former instead of the later one.

As a consequense of this change USB_SPEED_* values don't correspond
directly to EHCI speed encoding anymore, I've added necessary
recoding in EHCI driver. Also there is no point to put speed into
pipe anymore so it's removed and a bunch of host drivers fixed to
look at usb_device->speed instead.

Old usbdescriptors.h included is not removed as it seems to be
used by old USB device code.

This makes usb.h and usbdevice.h incompatible. Fortunately the
only place that tries to include both are the old MUSB code and
it needs usb.h only for USB_DMA_MINALIGN used in aligned attribute
on musb_regs structure but this attribute seems to be unneeded
(old MUSB code doesn't support any DMA at all).
