- Setup the rpmsg reserved memory, one is used for vring, the other one
is used for shared buffers.
- The mailbox of the lsio mu5a is used by rpmsg on imx8qxp platforms

There are two ways for SDMA accessing SPBA devices: one is SDMA->AIPS
->SPBA(masterA port), another is SDMA->SPBA(masterC port). Please refer
to the 'Figure 58-1. i.MX 6Dual/6Quad SPBA connectivity' of i.mx6DQ
Reference Manual. SDMA provide the corresponding app_2_mcu/mcu_2_app and
shp_2_mcu/mcu_2_shp script for such two options. So both AIPS and SPBA
scripts should keep the same behaviour, the issue only caught in AIPS
script sounds not solide.
The issue is more likely as the ecspi errata
ERR009165(http://www.nxp.com/docs/en/errata/IMX6DQCE.pdf):
eCSPI: TXFIFO empty flag glitch can cause the current FIFO transfer to
be sent twice
So revert commit 'dd4b487b32a3' firstly.

The i.MX8QuadMax is a Dual (2x) Cortex-A72 and Quad (4x) Cortex-A53
proccessor with powerful graphic and multimedia features.
This patch adds i.MX8QuadMax MEK board support.
Note that MX8QM needs a special workaround for TLB flush due to a SoC
errata, otherwise there may be random crash if enable both clusters of
A72 and A53. As the errata workaround is still not in mainline, so we
disable A72 cluster first for MX8QM MEK.

MX8 SoC is comprised of a few HW subsystems while some of them can be
reused in the different SoCs. So let's re-orginize them into subsystems
in device tree as well for the possible reuse of the common part.
Note, as there's still no devices of hsio subsys, so removed it
first instead of creating a subsys headfile with no devices.
They will be added back when new devices added.

Pull cramfs fix from Al Viro:
"Regression fix, fallen through the cracks"
* 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
cramfs: fix usage on non-MTD device
When both CONFIG_CRAMFS_MTD and CONFIG_CRAMFS_BLOCKDEV are enabled, if
we fail to mount on MTD, we don't try on block device.
Note: this relies upon cramfs_mtd_fill_super() leaving no side
effects on fc state in case of failure; in general, failing
get_tree_...() does *not* mean "fine to try again"; e.g. parsed
options might've been consumed by fill_super callback and freed
on failure.
Fixes: 74f78fc5ef ("vfs: Convert cramfs to use the new mount API")
