9a30903b44 spi: mxc_spi: Update pre and post divider algorithm
The spi clock divisor is of the form x * (2**y),  or  x  << y, where x is
1 to 16, and y is 0 to 15. Note the similarity with floating point numbers.
Convert the desired divisor to the smallest number which is >= desired divisor,
and can be represented in this form. The previous algorithm chose a divisor
which could be almost twice as large as needed.

8d4c4ffb95 spi: mxc_spi: Fix pre and post divider calculation
Fix two issues with the calculation of pre_div and post_div:

1. pre_div: While the calculation of pre_div looks correct, to set the
CONREG[15-12] bits pre_div needs to be decremented by 1:

The i.MX 6Dual/6Quad Applications Processor Reference Manual (IMX6DQRM
Rev. 0, 11/2012) states:

CONREG[15-12]: PRE_DIVIDER
0000 Divide by 1
0001 Divide by 2
0010 Divide by 3
...
1101 Divide by 14
1110 Divide by 15
1111 Divide by 16

I.e. if we want to divide by 2, we have to write 1 to CONREG[15-12].

2. In case the post divider becomes necessary, pre_div will be divided by
16. So set pre_div to 16, too. And not 15.

Both issues above are tested using the following examples:

clk_src = 60000000 (60MHz, default i.MX6 ECSPI clock)

a) max_hz == 23000000 (23MHz, max i.MX6 ECSPI read clock)

-> pre_div =  3 (divide by 3 => CONREG[15-12] == 2)
-> post_div = 0 (divide by 1 => CONREG[11- 8] == 0)
               => 60MHz / 3 = 20MHz SPI clock

b) max_hz == 2000000 (2MHz)

-> pre_div =  16 (divide by 16 => CONREG[15-12] == 15)
-> post_div = 1  (divide by  2 => CONREG[11- 8] == 1)
               => 60MHz / 32 = 1.875MHz SPI clock

c) max_hz == 1000000 (1MHz)

-> pre_div =  16 (divide by 16 => CONREG[15-12] == 15)
-> post_div = 2  (divide by  4 => CONREG[11- 8] == 2)
               => 60MHz / 64 = 937.5kHz SPI clock

d) max_hz == 500000 (500kHz)

-> pre_div =  16 (divide by 16 => CONREG[15-12] == 15)
-> post_div = 3  (divide by  8 => CONREG[11- 8] == 3)
               => 60MHz / 128 = 468.75kHz SPI clock

7fb72c7979 ARM: imx: Fix incorrect usage of CONFIG_SYS_MMC_ENV_PART
When running the "save" command several times on a mx6qsabresd we see:

U-Boot > save
Saving Environment to MMC...
Writing to MMC(1)... done
U-Boot > save

MMC partition switch failed

U-Boot > save
Saving Environment to MMC...
MMC partition switch failed
U-Boot > save
Saving Environment to MMC...
Writing to MMC(1)... done
U-Boot > save
Saving Environment to MMC...
MMC partition switch failed

This issue is caused by the incorrect usage of CONFIG_SYS_MMC_ENV_PART.

CONFIG_SYS_MMC_ENV_PART should be used to specify the mmc partition that stores
the environment variables.

On some imx boards it is been incorrectly used to pass the partition of kernel
and dtb files for the 'mmcpart' script variable.

Remove the CONFIG_SYS_MMC_ENV_PART usage and configure the 'mmcpart' variable
directly.

0c54f4b7c8 mx6: mx6qsabrelite/nitrogen6x: Remove incorrect setting of gpio CS signal
The number of gpio signal is packed inside CONFIG_SF_DEFAULT_CS macro
(shifted and or'ed with chip select), so it's incorrect to pass
that macro directly as an argument to gpio_direction_output() call.

Also, SPI driver sets the direction and initial value of a gpio,
used as a chip select signal, before any actual activity happens
on the bus.

So, it is safe to just remove the gpio_direction_output call,
that works incorrectly, thus making no effect, anyway.
