Hi,
when compiling latest HEAD for brcm2708 with this diffconfig:
{{{
CONFIG_TARGET_brcm2708=y
CONFIG_TARGET_brcm2708_RaspberryPi=y
CONFIG_TARGET_BOARD="brcm2708"
}}}
then I get:
{{{
make[2] target/compile
make[3] -C target/linux compile
make -r world: build failed. Please re-run make with V=s to see what's
going on
/home/josch/openwrt/include/toplevel.mk:173: recipe for target 'world'
failed
make: *** [world] Error 1
}}}
re-running with V=s gets me:
{{{

and waits for my input.
Since this used to work, I found the following first bad commit:
{{{
commit f3fe23c06a8a00ccaa78ef55e1495b8921e39f9e
Author: nbd <nbd@3c298f89-4303-0410-b956-a3cf2f4a3e73>
Date: Mon Jan 5 13:02:44 2015 +0000
all targets: remove all =m kernel config symbols
modules build during the kernel compile phase are ignored anyway,
all modules should be built using KernelPackage in
package/kernel/linux/modules/*
selecting the appropriate config symbols there rather than in
target/linux/*/config-*

Reverting the relevant hunks of above commit, the following patch makes it
work again:
