kernel, ramdisk: some boot unification
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/ Change-Id: I68910ba4e96ee80f7a12b65e48b5d39b43ca6397

|

For people building ARM images, the procedure has changed
|
||||
a bit. You need a full FS to boot now. In short, you need
|
||||
to use the new in-tree script to make a full SD image. See
|
||||
http://wiki.minix3.org/en/DevelopersGuide/MinixOnARM
|
||||
for details.
