The new configs/imx28_xea_sb_defconfig is introduced to facilitate building the single binary u-boot.sb fox XEA board.

The biggest distinction from "normal" XEA imx28_xea_sb_defconfig is support for USB mass storage devices (pen drives).

To achieve that, the CONFIG_DM_USB is enabled and supported.

This change provides the possibility to build XEA (imx287 based) board U-Boot as a single binary (without support for CONFIG_SPL_FRAMEWORK).

The generated u-boot.sb can be used in the factory environment to for example perform initial setup or HW testing.

It can be used with 'uuu' utility (SDPS: boot -f /srv/tftp/xea/u-boot.sb)

The board_init_ll() is used in arch/arm/cpu/arm926ejs/mxs/start.S, which is utilized when CONFIG_SPL_FRAMEWORK is disabled.

However, when it is enabled the arch/arm/cpu/arm926ejs/start.S is used, which requires the lowlevel_init() function.

I know checkpatch.pl has a warning, but maybe the text needs to be tweaked there slightly? Using CONFIG_IS_ENABLED here is less readable / clear than CONFIG_SPL_BUILD (which is special) and CONFIG_SPL_FRAMEWORK (there's no CONFIG_FRAMEWORK and this board isn't going to use TPL).
