From 203231f1f850c8227514bfc63b948f1c60abdc3b Mon Sep 17 00:00:00 2001 From: Darren Hart Date: Tue, 1 May 2012 21:14:18 -0700 Subject: initrdscripts: Update install.sh to work with mmc devices Fixes [YOCTO #2385] The installer only searches for hd[ab] sd[ab]. Some newer BSPs have mmcblk devices that should be used as the install target. These devices also have a partition prefix (mmcblk0p1 instead of mmcblk01). As they are detected asynchronously, it is necessary to add the rootwait kernel parameter to avoid a race condition trying to mount the root device. As BSPs like the FRI2 and the sys940x have mmc devices and will have a 1.2 release, we should push this to 1.2.1. The changes are perfectly contained and easily verified. Test for an mmcblk device and add the p partition prefix if necessary. Add the rootwait kernel parameter when an mmcblk device is detected. Replace the series of explicit umount commands with a single umount using a wildcard. This will find all the partitions and will not try to unmount non-existant devices. Avoid copy and paste errors by replacing /dev/${device}${pX} references with the previously assigned rootfs, bootfs, and swap variables. These changes have been tested on the FRI2 Sato image which installed to /dev/mmcblk0 as well as the N450 Sato image which installed to /dev/sda. Both were successful.
