3eb90bad65 Generic udelay() with watchdog support
According to the PPC reference implementation the udelay() function is
responsible for resetting the watchdog timer as frequently as needed.
Most other architectures do not meet that requirement, so long-running
operations might result in a watchdog reset.

This patch adds a generic udelay() function which takes care of
resetting the watchdog before calling an architecture-specific
__udelay().

AT91sam9g45 series is an ARM 926ej-s SOC family clocked at 400/133MHz.
It embeds USB high speed host and device, LCD, DDR2 RAM, and a full set of
peripherals.

The first board that embeds at91sam9g45 chip is the AT91SAM9G45-EKES.
On the board you can find 2 USART, USB high speed,
a 480*272 LG lcd, ethernet, gpio/joystick/buttons.

f62fb99941 Fix all linker script to handle all rodata sections
A recent gcc added a new unaligned rodata section called '.rodata.str1.1',
which needs to be added the the linker script.  Instead of just adding this
one section, we use a wildcard ".rodata*" to get all rodata linker section
gcc has now and might add in the future.

However, '*(.rodata*)' by itself will result in sub-optimal section
ordering.  The sections will be sorted by object file, which causes extra
padding between the unaligned rodata.str.1.1 of one object file and the
aligned rodata of the next object file.  This is easy to fix by using the
SORT_BY_ALIGNMENT command.

This patch has not be tested one most of the boards modified.  Some boards
have a linker script that looks something like this:

*(.text)
. = ALIGN(16);
*(.rodata)
*(.rodata.str1.4)
*(.eh_frame)

I change this to:

*(.text)
. = ALIGN(16);
*(.eh_frame)
*(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*)))

This means the start of rodata will no longer be 16 bytes aligned.
However, the boundary between text and rodata/eh_frame is still aligned to
16 bytes, which is what I think the real purpose of the ALIGN call is.

3e0cda071a AT91: Enable PLLB for USB
At least some (old ?) versions of the AT91Bootstrap do not set up the

This patch sets up the PLLB to the same values Linux uses, and makes USB
work ok on the following CPUs:
	- AT91CAP9
	- AT91SAM9260
	- AT91SAM9263

This patch also defines CONFIG_USB_STORAGE and CONFIG_CMD_FAT for all
the relevant AT91CAP9/AT91SAM9 atmel boards.
