Currently only MX6Q/QP sabresd boards are supported in SPL.
In order to also support MX6DL we need to convert to using

Other than that move the <asm/arch/mx6-ddr.h> header inclusion to the

Since commit ce412b79e7 ("drivers: net: phy: atheros: add separate
config for AR8031") ethernet does not work on mx6sabresd.
This commit correctly assigns ar8031_config() as the configuration
function for AR8031 in the same way as done in the Linux kernel.
However, on mx6sabresd design we need some additional configuration,
such as enabling the 125 MHz AR8031 output that needs to be done
in the board file.
This also aligns with the same method that the kernel performs
the AR8031 fixup in arch/arm/mach-imx/mach-imx6q.c.

When using SPL on i.mx6 we frequently notice some DDR initialization
mismatches between the SPL code and the non-SPL code.
This causes stability issues like the ones reported at 7dbda25ecd
("mx6ul_14x14_evk: Pass refsel and refr fields to avoid hang") and also:
http://lists.denx.de/pipermail/u-boot/2016-September/266355.html .
As the non-SPL code have been tested for long time and proves to be reliable,
let's configure the DDR in the exact same way as the non-SPL case.
The idea is simple: just use the DCD table and write directly to the DDR
registers.
Retrieved the DCD tables from:
board/freescale/mx6sabresd/mx6q_4x_mt41j128.cfg
and
board/freescale/mx6sabresd/mx6qp.cfg
(NXP U-Boot branch imx_v2015.04_4.1.15_1.0.0_ga)
This method makes it easier for people converting from non-SPL to SPL code.
Other benefit is that the SPL binary size is reduced from 44 kB to 39.9 kB.

"For a reliable power on reset, suggest to keep asserting the reset
low long enough (10ms) to ensure the clock is stable and clock-to-reset
1ms requirement is satisfied."
So do as suggested and also add a 100us delay after deasserting the
reset line to guarantee that the PHY ID can be read correctly and the
Atheros 8031 PHY driver can be loaded automatically.
This results in a simpler code.

MXC SPI driver has a feature whereas a GPIO line can be used to force CS high
across multiple transactions. This is set up by embedding the GPIO information
in the CS value:
cs = (cs | gpio << 8)
This merge of cs and gpio data into one value breaks the sf probe command:
if the use of gpio is required, invoking "sf probe <cs>" will not work, because
the CS argument doesn't have the GPIO information in it. Instead, the user must
use "sf probe <cs | gpio << 8>". For example, if bank 2 gpio 30 is used to force
cs high on cs 0, bus 0, then instead of typing "sf probe 0" the user now must
type "sf probe 15872".
This is inconsistent with the description of the sf probe command, and forces
the user to be aware of implementaiton details.
Fix this by introducing a new board function: board_spi_cs_gpio(), which will
accept a naked CS value, and provide the driver with the relevant GPIO, if one
is necessary.
