nand_omap_bch_decoder: Fix up error detection ...

Bit errors in the ECC itself are not beeing taken into account.
In this cases the number of detected errors != number of corrected errors and
chien search returns an error.
This patch adds detection of bit errors in the ECC.

uart drivers: use xzalloc instead of xmalloc ...

The flags in struct console_device have to be initialized
to zero. Otherwise the following can happen:

- console_register sets the initial baudrate of a new console
  before we set the global console init state to CONSOLE_INIT_FULL.
- In console_baudrate_set we test whether the current console is
  active which may be true because of unitialized flags.
- we then call getc() to wait for the user to accept the new settings
  and we are stuck because of the CONSOLE_UNINITIALIZED state
  we will never get anything from getc().

Looking back this explains some cases for me when barebox refused
to start and I really wonder why this did not become a more visible
problem before.

mtd nand: fix oob compile time option ...

The NAND_READ_OOB Kconfig option is used to

a) creating a cdev for reading OOB data
b) compiling in mtd->read_oob support

The former was intended and that's also what the Kconfig help
says. The latter though was implicit and wrong. mtd->read_oob
is also used by the bbt code which resulted in a NULL pointer
deref when compiled with BBT but without NAND_READ_OOB.
To fix this, split the option into two. The now invisible
option NAND_OOB_DEVICE is only responsible for b) and gets
selected when necessary.

This is needed for the ohci-at91 to work.

In u-boot this function was transmitting a cmdlen of 12, by the initial

usb_read_capacity nearby which also transmit 12 byte per default on
u-boot, which probably also need a fix.

usb/gadget: make serial gadget resistant to cable unplug ...

As USB can have its cable plugged out anytime, make the
serial gadget reliable in case of unplugging :
 - unregister the gadget_serial provided console
 - don't stay forever in the read loop if connection was cut

This behaviour relies on correct implementation of
usb_gadget_poll(), which should return an error if the USB
cable was removed.
