USB: gadget: atmel_usba_udc: fix transfer hang issue

When receive data, the RXRDY in status register set by hardware
after a new packet has been stored in the endpoint FIFO. After,
we copy from FIFO, we clear it, make the FIFO can be accessed
again.
In the receive_data() function, this bit RXRDY has been cleared.
So, after the receive_data() function return, this bit should
not be cleared again, or else it will cause the accessing FIFO
corrupt, which will make the data loss.

fastboot: add support for continue command

The fastboot continue command is defined to exit fastboot and continue
autoboot. This commit implements the continue command and the exiting of
fastboot only. Subsequent u-boot commands can be processed after exiting
fastboot. Autoboot should implement a boot script such as "fastboot; mmc
read <...>; bootm" to fully implement the fastboot continue function.

dfu: mmc: check if mmc device exists in mmc_block_op()

The function mmc_block_op() is the last function before
the physicall data write, but the mmc device pointer is not
checked. If mmc device not exists, then data abort will occur.
To avoid this, first the mmc device pointer is checked.

dfu: dfu_get_buf: check the value of env dfu_bufsiz before use

In function dfu_get_buf(), the size of allocated buffer could
be defined by the env variable. The size from this variable
was passed for memalign() without checking its value.
And the the memalign will return non null pointer for size 0.

This could possibly cause data abort, so now the value of var
is checked before use. And if this variable is set to 0 then
the default size will be used.

This commit also changes the base passed to simple_strtoul()
to 0. Now decimal and hex values can be used for the variable
dfu_bufsiz.

x86: ifdtool: Add support for early microcode access

Some Intel CPUs use an 'FSP' binary blob which provides an inflexible
means of starting up the CPU. One result is that microcode updates can only
be done before RAM is available and therefore parsing of the device tree
is impracticle.

Worse, the addess of the microcode update must be stored in ROM since a
pointer to its start address and size is passed to the 'FSP' blob. It is
not possible to perform any calculations to obtain the address and size.

To work around this, ifdtool is enhanced to work out the address and size of
the first microcode update it finds in the supplied device tree. It then
writes these into the correct place in the ROM. U-Boot can then start up
the FSP correctly.

x86: Correct problems in the microcode loading

There are several problems in the code. The device tree decode is incorrect
in ways that are masked due to a matching bug. Both are fixed. Also
microcode_read_rev() should be inline and called before the microcode is
written.

Note: microcode writing does not work correctly on ivybridge for me. Further
work is needed to resolve this. But this patch tidies up the existing code
so that will be easier.
