[PATCH v2 0/3] imx6ul: add Technexion Pico Hobbit support

[Michael Grzeschik]

This series adds support for the Technexion Pico Hobbit. It also
prepares the TX_CLK_DIR pins for imx6ul platforms. This way it
will not be needed in every imx6ul based board files.

[PATCH v2 1/3] ARM: i.MX: setup ENET_TX_CLK_DIR in imx6_init for every imx6ul

[Michael Grzeschik]

We generically enable the output of ENET_TX_CLK.
It will be output if ENET_REF_CLK is selected.

[PATCH v2 2/3] ARM: phytec-som-imx6: remove needles enet refclk setup

[Michael Grzeschik]

All REF_CLK output setup now is generically prepared for imx6ul. The
handling of the ENET_CLK_SEL (gpr[13]|gpr[14]) bits is not necessary, as
0 is their reset value.

[PATCH v2 3/3] ARM: i.MX6: add Technexion Pico Hobbit support

[Michael Grzeschik]

This adds support support for the i.MX6UL Technexion Pico Hobbit.
The board comes with different amounts of RAM. We create one image
for the 256MB and one for the 512MB variant.

Recent Kernels support phy-reset-post-delay. Can we just add support for
it in barebox aswell?

Could we for now stick with this? When I write the phy-reset-post-delay
patches I will then adopt this node in the regarding series. This gives
me some time, as I can not test the post-delay patch in the next two
weeks.

Thanks,
Michael

Ok, I reworded the comment to:

	/*
	 * There are two possible ways to start the phy. Let the hardware
	 * reset it properly or reset it a second time in software.
	 * Unfortunetly the phy needs some microseconds after reset to
	 * settle down.
	 * FIXME: Port support for the "phy-reset-post-delay" property to
	 *        barebox.
	 */
