spi: mxc_spi: Fix ECSPI reset handling

Reviewing the ECSPI reset handling shows two issues:

1. For the enable/reset bit (MXC_CSPICTRL_EN) in the control reg
   (ECSPIx_CONGREG) the i.MX6 technical reference manual states:

   -- cut --
   ECSPIx_CONREG[0]: EN: Writing zero to this bit disables the block
   and resets the internal logic with the exception of the ECSPI_CONREG.
   -- cut --

   Note the exception mentioned: The CONREG itself isn't reset.

   Fix this by manually writing the reset value 0 to the whole register.
   This sets the EN bit to zero, too (i.e. includes the old
   ~MXC_CSPICTRL_EN).

2. We want to reset the whole SPI block here. So it makes no sense
   to first read the old value of the CONREG and write it back, later.
   This will give us the old (historic/random) value of the CONREG back.
   And doesn't reset the CONREG.

   To get a clean CONREG after the reset of the block, too, don't use
   the old (historic/random) value of the CONREG while doing the reset.
   And read the clean CONREG after the reset.

This was found while working on a SPI boot device where the i.MX6 boot
ROM has already initialized the SPI block. The initialization by the
boot ROM might be different to what the U-Boot driver wants to configure.
I.e. we need a clean reset of SPI block, including the CONREG.

http://patchwork.ozlabs.org/patch/140863/
http://lists.denx.de/pipermail/u-boot/2011-April/089606.html

This patch corrects the addresses used when working with Spansion/AMD FLASH chips.
Addressing for 8 and 16 bits is almost identical except in the 16-bit case the
LSB of the address is always 0.  The confusion arose because the addresses
in the datasheet for 16-bit mode are word addresses but this code assumed it was
byte addresses.

I have only been able to test this on our Octeon boards which use either an 8-bit
or 16-bit bus.  I have not tested the case where there's an 8-bit part on a 16-bit
bus.

This patch also adds some delays as suggested by Spansion.

If a part can be both 8 and 16-bits, it forces it to work in 8-bit mode if an
8-bit bus is detected.

Apart from the pulled changes, fixed few minor code cleanups and tested
on 256M29EW, 512M29EW flashes.

3. tcmp is an unsigned value, so (tcmp < 0) will never be true and the if
which checks that condition will never execute. Also, there should be no

Second, the reset value of the timers were being calculated to give an overall

When running this command the menu will be assembled as defined
by a set of environment variables which contain a title and
command key-value pairs. The "Up" and "Down" keys are used for
navigation through the items. Current active menu item is
highlighted and can be selected using the "Enter" key.

sequencies, so for proper menu rendering and item selection
the used terminal should support them.
