ARM: 8951/1: Fix Kexec compilation issue.
[ Upstream commit 76950f7162cad51d2200ebd22c620c14af38f718 ]
To perform the reserve_crashkernel() operation kexec uses SECTION_SIZE to
find a memblock in a range.
SECTION_SIZE is not defined for nommu systems. Trying to compile kexec in
these conditions results in a build error:
linux/arch/arm/kernel/setup.c: In function ‘reserve_crashkernel’:
linux/arch/arm/kernel/setup.c:1016:25: error: ‘SECTION_SIZE’ undeclared
(first use in this function); did you mean ‘SECTIONS_WIDTH’?
crash_size, SECTION_SIZE);
^~~~~~~~~~~~
SECTIONS_WIDTH
linux/arch/arm/kernel/setup.c:1016:25: note: each undeclared identifier
is reported only once for each function it appears in
linux/scripts/Makefile.build:265: recipe for target 'arch/arm/kernel/setup.o'
failed
Make KEXEC depend on MMU to fix the compilation issue.
