[PATCHv2 1/2] image_types_fsl.bbclass: Add U-Boot NAND support for i.MX23/i.MX28

[Alexey Ignatov]

This adds support to generate the U-Boot image for use with NAND
(uboot.mxsboot-nand) and allows for custom params to be given for
mxsboot using the MXSBOOT_NAND_ARGS variable which should be defined
in the machine definition file.

[PATCHv2 2/2] imx28evk: Add U-Boot NAND image generation support

[Alexey Ignatov]

This defines NAND parameters for u-boot.mxsboot-nand image creation
similar to those used for UBI image (for K9LBG08U0D-PCB chip):
- page size: 4 k
- OOB size: 218 bytes
- erase size: 512 k
