This patch resolves the following build errors for I2C driver in
VCMA9:

In file included from s3c24x0_i2c.c:40:0:
s3c24x0_i2c.h:38:17: error: field 'id' has incomplete type

Which U-Boot do you use? I just tried current head of mainline:

[hs at pollux u-boot]$ git log

     m68k/lib: fix serial driver relocation

     Fix coldfire serial driver bindings no more relocated to ram after last
     changes to drivers/serial/serial.c (regression).
     Serial initialization in ram has to be called after that gd->reloc_off is
     calculated.

and it compiles clean with eldk-5.2:

[hs at pollux u-boot]$ ./MAKEALL VCMA9
