[U-Boot] [PATCH 1/3] ARM: imx6q_logic: Enable 256KB OCRAM

[U-Boot] [PATCH 1/3] ARM: imx6q_logic: Enable 256KB OCRAM

[Adam Ford]

Since this board config only supports, the i.MX6D/i.MX6Q configurations,
256K of on-chip RAM is available which increases the space available
to SPL to help further reduce board code and further enable device tree
functions.

This patch enables 256K of RAM.

[U-Boot] [PATCH 2/3] ARM: imx6q_logic: Enable Pin muxing in SPL

[Adam Ford]

With the 256KB of OCRAM available to SPL now, there should be
enough room to enable the pinmuxing in SPL from the device tree.

This patch enables SPL_PINCTRL et al and adds the serial and
usdhc pin mux references to the -u-boot.dtsi file so the pins can be
configured from the device tree.

[U-Boot] [PATCH 3/3] ARM: imx6q_logic: Remove legacy pinmuxing code from board file.

[Adam Ford]

With the OCRAM expanded to 256KB and the SPL_PINCTRL enabled with
-u-boot.dtsi entries to include the pinmuxing in SPL, the manual
code setting up the pinmux can go away.

This patch removes the legacy pinmuxing code from the board file.
