1Pre-compiled modules
2====================
3
4Some modules are pre-compiled due to needing cross-compilers present on the
5build/dev machine which is inconvenient. Makefile is ready to compile them again
6in case they are missing:
7
81) Prepare the linux kernel trees to build external modules, i.e.:
9
10   kernel $ make ARCH=<arch> CROSS_COMPILER=<cross-compiler-prefix> defconfig
11   kernel $ make ARCH=<arch> CROSS_COMPILER=<cross-compiler-prefix> modules_prepare
12
13   For each architecture. See the Makefile to check which are the supported architectures.
14
152) Export the variables below to point to the right place:
16
17   KDIR_<arch>:                for each architecture it needs to point to a
18                               kernel tree configured as in (1)
19
20   CROSS_COMPILER_<arch:       for each architecture it needs to point to the
21			       correct toolchain prefix. Leave it blank if a
22			       cross-compiler is not needed (example: you are
23			       building a 32b module with a multilib compiler).
24
25
263) Remove every %-<arch>.ko. After this the build system will recreate them.
