The default settings store the persistent environment on SD card
and not serial flash (SPI NOR).

To use SPI NOR to save the environment instead of SD card, edit
include/configs/mx6qsabrelite.h and

- undefine CONFIG_ENV_IS_IN_MMC
- define   CONFIG_ENV_IS_IN_SPI_FLASH

The SPI driver can take as chip select the controller's chip selects
as well as an external GPIO. The LSB byte has the value of the internal
chip select, the highest (thought as 16-bit value) contains the GPIO
number.

The GPIO used on Sabre Lite is GP3:19 == 83.

The interface to the mxc_gpio driver uses integer (ordinal) values to
refer to all GPIOs on the i.MX processors. The registers themselves
and much of the i.MX documentation are banked in groups of 32, and these
macros allow the use of the port:index numbering for clarity.

GPIO_NUMBER() converts to ordinal value from port:index
GPIO_PORT() returns the port of an ordinal value
GPIO_INDEX() returns the index or offset of the ordinal.

This patch fixes booting i.MX28 CPUs via USB download.
In this mode the CPU's bootrom implements a USB HID device that
accepts a bootstream.

When downloading the bootstream via USB, first the SPL code is
received and executed. Then the u-boot image is received and
called.

The USB bootmode is interrupt driven.

This patch fixes two things:

1) The ARM's fast interrupt mode is disabled when the SPL code
has been run. So save and restore the CPSR register.

2) Save and restore c1 control register: the exception vector
location needs to be set back to bootrom space to make the USB
interrupts work again. The SPL code needs to change this
option for the ram size probing.

The interrupt acknowledge action have to run after the
registered interrupt handler. So we have a chance to
bear out the corresponding interrupt request in the
corresponding controller hardware.

With this reordering, we optain a proper interrupt
handling for level triggered interrupt sources -- for
example the new axi_timer v1.02.a introduced in ISE 13.2.

Align the card status polling with the Linux kernel and retry the
command at least five times. Also some cards apparently mishandle the
status bits, so make sure to check the card state too.

A MMC/SD card may always go into the programming state (and hence be
busy) after a block write. Therefore always check the card state, even
after single block writes. On the other hand there is no need to check
the card status after a read.

Also make sure that errors during busy polling are propagated upwards.

We are seeing occasional timeouts in the Tegra mmc code when
we are reading from external MMC cards. These don't seem to be
detrimental if they are handled properly.  This CL properly
clears the "normal interrupt status register" (norintsts) in
error conditions.  If we don't do this, when we come back into
mmc_send_cmd() the register will still contain status from the
last transaction.

Before we can send a command we need both the DATI (command inhibit on
mmc_dat line) bit and CMDI (command inhibit on mmc_cmd line) are clear.
The previous behavior of only checking on DATI was insufficient on some
cards and incorrect behavior in any case.  This makes the code check
for both bits being clear and makes the error print more clear as
to what happened.  DATI_CMDDIS is removed as it was unused elsewhere
in the code and stood for 'DATI is set, cmds are disabled still'.
