This patch moves the logic behind U-Boot proper BOARD_SIZE_CHECK
into a common function that is called for SPL, too.
For SPL, CONFIG_SPL_MAX_SIZE is used to check u-boot-spl-dtb.bin.
This is RFC for two reasons:
- scripts/Kbuild.include might not be the perfect place for this
new function but was the only place I found included by both
/Makefile and /scripts/Makefile.spl
- CONFIG_SPL_MAX_SIZE at least for some boards defines the size
of the initially available SRAM. However, this check checks the
SPL binary only. Initial SRAM must hold gd, heap and stack in
addition to that.

So, a problem is that we need to get at values after they've been
pre-processed:
/bin/sh: 1: printf: (SRAM_SCRATCH_SPACE_ADDR - CONFIG_SPL_TEXT_BASE): expected
numeric value
spl/u-boot-spl-dtb.bin exceeds file size limit:
limit: 0 bytes
actual: 124970 bytes
excess: 124970 bytes
../scripts/Makefile.spl:266: recipe for target 'spl/u-boot-spl-dtb.bin' failed
Right. We could run the define through libt/asm-offsets.c (just like
GENERATED_GBL_DATA_SIZE is created), but how would we get the result
back into the Makefile?

Simon
