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.

i.MX6: mx6qsabrelite: README: don't pass chip-select to sf probe command
board/freescale/mx6qsabrelite/README explain a procedure to
update the SPI-NOR on the SabreLite board without Freescale

"sf erase" and "sf write" failing on a mx6qsabrelite board:
MX6QSABRELITE U-Boot > sf probe 1

SPI flash erase failed
MX6QSABRELITE U-Boot > sf write 0x10800000 0 0x40000

This is because the chip-select 1 is wrong and the correct

the chip-select and bus arguments for the sf probe command are optional

ARM: OMAP4+: Cleanup the clocks layer
Currently there is quite a lot of code which
is duplicated in the clocks code for OMAP 4 and 5
Socs. Avoiding this here by moving the clocks
data to a SOC specific place and the sharing the
common code.
This helps in addition of a new Soc with minimal
changes.

ARM: OMAP4+: Change the PRCM structure prototype common for all Socs
The current PRCM structure prototype directly matches the hardware
register layout. So there is a need to change this for every new silicon
revision which has register space changes.
Avoiding this by making the prototye generic and populating the register
addresses seperately for all Socs.

ARM: OMAP4+: emif: Detect SDRAM from SDRAM config register
Now SDRAM initialization is done on the basis of omap revision.
Instead this should be done on basis of SDRAM type read from
EMIF_SDRAM_CONFIG register. This will be helpful to avoid
unnessecary cpu checks for new boards

lcd: implement a callback for splashimage
On some architectures certain values of splashimage will lead to
a data abort exception.
Document the problem, and implement a callback for splashimage to
reject such values.
