spi: i.MX: optimize transfers for ECSPI v2.3 ...

Instead of writing one word to the txfifo and then wait until
one is received in the rxfifo we can write while the txfifos
are not full and read as long the rxfifos contain data. This
makes transfers for the m25p80 driver around 7 times faster
here.

Unlike the last version this time we only optimize the common
case with 8 bits per word and SPI_LSB_FIRST cleared. The other
cases would require more bit shuffling of the data.

video: i.MX IPUv3: Set ldb clocks correctly ...

The clocks for the LVDS display bridge have a fixed /3.5 and a
configurable /1,/2 divider in their path. The configurable divider has
to be explicitly configured for single/dual channel support, so we can't
rely on clock rate parent propagation here. Clear the
CLK_SET_RATE_PARENT flag for the configurable divider and configure the
clock explicitly in the ldb driver.
Tested on a custom i.MX6 board, currently untested on i.MX53.

ARM: pfla02: append suffix 1bank ...

In the current naming schema the phyFLEX-i.MX6 variants which only use
one bank for memory have the suffix "1bank". The variants which use two
banks of memory have no suffix.

The patch fixes the name of the phyFLEX-i.MX6 Solo variant with 512MiB
on one bank. So the name of the image file changes from
    barebox-phytec-pbab01s-512mb.img
    barebox-phytec-phyboard-subra-512mb.img
to
    barebox-phytec-pbab01s-512mb-1bank.img
    barebox-phytec-phyboard-subra-512mb-1bank.img

This patch touches the phyFLEX-i.MX6 Kit variant and the
phyBOARD-SUBRA-i.MX6 which shares the same phyFLEX-i.MX6 module.

ARM: phytec-som-imx6: set loadaddr to start of DDR memory. ...

The loadaddr in the flash-headers for the phyFLEX/phyCARD-i.MX6 was set
to 0x20000000 (512MiB). The start of the DDR memory in CPU's memory map
is 0x10000000 (256MiB). So the ROM loader loads the barebox image at the
memory position 256MiB and higher in the DDR memory.

This is a problem when the module doesn't have more than 256MiB of
memory. Therefore the loadaddr is set to the start of the DDR memory.

The patch was tested on a phyFLEX-i.MX6 Quad with 1GiB RAM on one bank
and on a phyCARD-i.MX6 Quad 1GiB RAM on two banks.

boards: Add phytec-som-imx6 ...

The main idea behind this patch is to avoid redundant code.  Because of
the module similarities of all i.MX6 based phytec boards, we can merge
its code.

The phytec-som-imx6 merges the code of all i.MX6 based phytec SOMs.  So
we will have only one "board" in the barebox for phyCARD-i.MX6 and
phyFLEX-i.MX6.
