The make macro to check if the binary exceeds the board size limit is
taken straight from the root Makefile.

Without this and e.g. enabled EFI Vybrid fails booting as the regular
size limit check does not take the final u-boot.imx binary size into
account which is bigger due to alignment as well as IMX header stuff.

The script return 1 when the required files not exists, return 0

We can have the case where u-boot is launched after some other low level
enabler, like for example when u-boot runs after arm-trusted-firmware
and/or optee. So, because of that we may need to jump the initialization of
some IP blocks even because we may no longer have the permission for that.

So, if the config option to skip low level init is set disable also timer,
board and csu initialization.

This patch adds system suspend/resume support,
when linux kernel enters deep sleep mode, SoC will go
into below mode:

 - CA7 platform goes into STOP mode;
 - SoC goes into DSM mode;
 - DDR goes into self-refresh mode;
 - CPU0/SCU will be powered down.

When wake up event arrives:

 - SoC DSM mdoe exits;
 - CA7 platform exit STOP mode, SCU/CPU0 power up;
 - Invalidate L1 cache;
 - DDR exit self-refresh mode;
 - Do secure monitor mode related initialization;
 - Jump to linux kernel resume entry.

Belwo is the log of 1 iteration of system suspend/resume:
