Explain why transfor to fixed-size-types or explain why we need the
ifndef around all structs?

The ifdef-protection against __KERNEL_STRICT_NAMES is needed to not break
code in the tools-dir which (implizitely) includes cpu.h. See this
compiler output:

> gcc -g -Wall -idirafter /mdata/gsrc/u-boot/include -idirafter
> /mdata/gsrc/u-boot/include2 -idirafter /mdata/gsrc/u-boot/include -I

> -DTEXT_BASE=0x80e80000 -DUSE_HOSTCC -D__KERNEL_STRICT_NAMES -O -c -o
