PROBLEM: linux kernel 2.6.20.6 build failed for ppc board chestnut(ibm ppc
750GX/FX)
STEPS I followed:
1) make ARCH=ppc CROSS_COMPILE=ppc_4xx- chestnut_defconfig # toolchain from
eldk 4.1
2) make ARCH=ppc CROSS_COMPILE=ppc_4xx- V=1
...
make -f scripts/Makefile.build obj=arch/ppc/platforms
ppc_4xx-gcc -m32 -Wp,-MD,arch/ppc/platforms/.chestnut.o.d -nostdinc -isystem /opt/eldk/usr/bin/../lib/gcc/powerpc-linux/4.0.0/include -D__KERNEL__ -Iinclude -include

arch/ppc/platforms/chestnut.o arch/ppc/platforms/chestnut.c
arch/ppc/platforms/chestnut.c: In function 'chestnut_setup_mtd':
arch/ppc/platforms/chestnut.c:435: error: 'physmap_map' undeclared (first use
in this function)
arch/ppc/platforms/chestnut.c:435: error: (Each undeclared identifier is
reported only once
arch/ppc/platforms/chestnut.c:435: error: for each function it appears in.)
make[1]: *** [arch/ppc/platforms/chestnut.o] Error 1
make: *** [arch/ppc/platforms] Error 2
This PROBLEM should also affect these boards:
find -name '*.[chS]' -exec grep physmap_map {} \; -print
physmap_map.size = CHESTNUT_32BIT_SIZE;
./arch/ppc/platforms/chestnut.c
physmap_map.size = size;
./arch/ppc/platforms/ev64360.c
physmap_map.size = size;
./arch/ppc/platforms/katana.c
I've veryfied 2.6.15, 2.6.19.2 2.6.20.1 2.6.20.6
ONLY 2.6.15 can build successfully. sounds like the problem is caused by the
interface change of mtd.
this brute force patch sould solve the problem:
diff -Nru /tmp/linux-2.6.20.6/arch/ppc/platforms/chestnut.c \
