Am hoping someone can still help me out with this; I've updating 60
-persistent-storage.rules, but still have a delay in start up. . . Looks
like to me there are other rules related to USB trying to access, please
help!

Bug description:
  As per JEDEC 4.5 spec for eMMC devices,
  There is a new partitions as part of eMMC storage devices it self. (Further details please refer eMMC spec)

  *In Linux Kernel@ 3.10.33, mmc driver has created a new partitions
  with "mmcblkXrpmb" if device expresses it support of RPMB.

  Issues observed:

  issue 1:
  RPMB (Replay Protected Memory Block), A signed access to a Replay Protected Memory Block is provided. This function provides means for the system to store data to the specific memory area in an authenticated and replay protected manner.
  In that case, any read/write access to this partition device will report errors.

  issue 2:
  The by-path, line is wrongly mapping to platform-sdhci-tegra.1  -> mmcblk2rpmb were as
  it should be platform-sdhci-tegra.1  -> mmcblk2

  ls -l /dev/disk/by-path/
  total 0
  lrwxrwxrwx 1 root root 17 Jan  3  2000 platform-sdhci-tegra.1 -> ../../mmcblk2rpmb
  lrwxrwxrwx 1 root root 15 Jan  3  2000 platform-sdhci-tegra.1-part1 -> ../../mmcblk2p1
  lrwxrwxrwx 1 root root 13 Jan  3  2000 platform-sdhci-tegra.2 -> ../../mmcblk1
  lrwxrwxrwx 1 root root 15 Jan  3  2000 platform-sdhci-tegra.2-part1 -> ../../mmcblk1p1
  lrwxrwxrwx 1 root root 17 Jan  3  2000 platform-sdhci-tegra.3 -> ../../mmcblk0rpmb
  lrwxrwxrwx 1 root root 15 Jan  3  2000 platform-sdhci-tegra.3-part1 -> ../../mmcblk0p1
  lrwxrwxrwx 1 root root 15 Jan  3  2000 platform-sdhci-tegra.3-part2 -> ../../mmcblk0p2

  We have locally resolved in our platform in this file 60-persistent-
  storage.rules

  For issue 1: (with this rule)
  # skip block read for partitions of type rpmb
  KERNEL=="mmcblk[0-9]rpmb", SUBSYSTEM=="block", GOTO="persistent_storage_end"

  For issue 2:
  ENV{DEVTYPE}=="disk", ENV{ID_PATH}=="?*", KERNEL=="mmcblk[0-9]rpmb", SYMLINK+="disk/by-path/$env{ID_PATH}-rpmb"
  ENV{DEVTYPE}=="disk", ENV{ID_PATH}=="?*", KERNEL!="mmcblk[0-9]rpmb", SYMLINK+="disk/by-path/$env{ID_PATH}"

  Please consider this issues fix in next udev release .

  
  SRU INFO: This is mostly an issue with running backported kernels on 12.04 and 14.04. There is no test case which would reproduce this on arbitrary hardware, but there are several reporters which are in a position to verify a proposed update.
