We used to load the memory driver above the other modules to allow
the memory driver (ramdisk) to grow. We no longer want or need this
this as we have a working mmc driver.
To use the new SD building script, Linux has to be configured with
loop.max_part=15 on the command line (or set at module load time)
to make the loopback device see the partitions.
This commit removes a lot of differences between the ARM and x86
boot ramdisk and rc scripts. It changes the ARM build from running
from ramdisk to requiring a full filesystem on the SD image and
booting into it.
. ramdisk: remove some arm-only utilities only used for running
from the shell
. remove ARM-only rc.arm, proto.arm.small, ttys and mylogin.sh
boot-time ramdisk files
. change kernel to add "arch" variable so userland knows what
we're running on from sysenv
. make ARM use the regular ramdisk rc file, changed to distinguish
i386-only and ARM-only drivers; requires rootdevname to be set
. change /etc/rc and /usr/etc/rc to start i386-only drivers only on
i386 systems
. change the kernel/arm to have a special case for the memory
driver to load it higher so it can be bigger
. add uEnv.txt, cmdline.txt and a for now highly linux-dependent
SD preparation script arm_sdimage.sh to the git repository in
releasetools/
