I have applied with some changes. See below.

I've improved this with a complete list of the firmware that it can
potentially install.

Renamed to:

	BR2_PACKAGE_FIRMWARE_IMX_NEEDS_SDMA_FW

to match the naming of the DDR firmware option.

When you look at the sdma folder, it contains:

sdma-imx25-to1.bin
sdma-imx31-to1.bin
sdma-imx31-to2.bin
sdma-imx35-to1.bin
sdma-imx35-to2.bin
sdma-imx51-to3.bin
sdma-imx53-to1.bin
sdma-imx6q.bin
sdma-imx7d.bin

So there is no firmware for i.MX37, i.MX50, i.MX6S and i.MX6UL, so I
dropped these from the supported platform.

Instead of repeating this, I've enclosed all options in a "if
BR2_PACKAGE_FIRMWARE_IMX ... endif" block.

Ditto naming.

Ditto dependency.

And same for the other options as well.

I fixed these issues when applying.

Thanks!
