I built grub under this configuration (GRUB for U-Boot platforms):
./autogen.sh
./configure \
--with-platform="uboot" \
--target="arm" \
--disable-efiemu \
--enable-mm-debug \
--enable-nls \
--enable-device-mapper \
--enable-cache-stats \
--enable-boot-time \
--enable-grub-mkfont \
--enable-grub-mount \
--prefix="/usr" \
--bindir="/usr/bin" \
--sbindir="/usr/bin" \
--mandir="/usr/share/man" \
--infodir="/usr/share/info" \
--datarootdir="/usr/share" \
--sysconfdir="/etc" \
--program-prefix="" \
--with-bootdir="/boot" \
--with-grubdir="grub" \
--disable-silent-rules \
--disable-werror
make
Those configurations comes from our grub's PKGBUILD [0] and our patch to
detect device tree folder [1]. Those files were created to build grub
for Parabola.
BTW, i created 2 U-Boot packages, the first one called
uboot-beaglebone-linux-libre to start up U-Boot without GRUB for our
linux-libre package. Here are the PKGBUILD [2] and a custom patch with
our custom modifications [3] based on uboot-beaglebone from Arch ARM
[4][5]. It was tested and works well in Parabola, also we put a
announcement [6] about it.
Note: we put linux-libre as suffix in our uboot-beaglebone package for
each specific kernel available in Parabola (eg.
uboot-beaglebone-linux-libre-lts for linux-libre-lts) because our kernel
images use custom names (eg. vmlinuz-linux-libre-grsec) in comparison to
Arch ARM (eg zImage for all kernels) to allow for 2 or more kernels in
the same system once we add GRUB compatibility for the future.
The second one is called uboot-grub-beaglebone, this uboot package was
created to start GRUB in ARMv7, it was based on
uboot-beaglebone-linux-libre. Here are our PKGBUILD [7] and patch [8]
for this package.
Otherwise, we've created a install file to install GRUB automatically
after installing [9], it was based on uboot-beaglebone-linux-libre too [10]
