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.

This patch adds SPI support for the MX28EVK. Support for
an optionally installed SPI flash is also added. An example

added but disabled by default.

SST25VF032B 32Mbit SPI flash.

Align the card status polling with the Linux kernel and retry the

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'.
