The bit MX25_H1_PM_BIT value is handled for port 1 as MX25_OTG_PM_BIT is
for port 0. The latter is called "OPM: OTG power mask" in the i.MX25
reference manual. Its description matches the description of "HPM: Host
power mask" for the host port which is bit 16, not 8.
The Linux kernel (as of 4.3) also has
#define MX25_H1_PM_BIT BIT(16)
.

The version is stored as BCD, e.g. 0x40 -> ".4" and 0x41 -> ".41".
The latter was getting printed as ".65". Simplify the logic a bit to
not split the minor into nybbles just to re-assemble it into a byte
again.

remap_range is for remapping regions with different cache attributes.
It is implemented for ARM and PowerPC only, the other architectures only
provide stubs.
Currently the new cache attributes are passed in an architecture specific
way and the attributes have to be retrieved by calls to
mmu_get_pte_cached_flags() and mmu_get_pte_uncached_flags().
Make this simpler by providing architecture independent flags which can
be directly passed to remap_range()
Also provide a MAP_ARCH_DEFAULT flag and a arch_can_remap() function.
The MAP_ARCH_DEFAULT defaults to whatever caching type the architecture
has as default. the arch_can_remap() function returns true if the
architecture can change the cache attributes, false otherwise. This
allows the memtest code to better find out what it has to do.

Currently we get a null pointer dereference when booting linux on RPi
which use "uart-pl011" driver. This driver doesn't implement a remove
driver callback. This patch adds a check before calling the remove
callback if the driver which use the amba bus implement such
functionality.

In drivers/usb/core/usb.c we already have le16_to_cpus() conversion
just after usb_get_descriptor():
390 /* correct le values */
391 le16_to_cpus(&dev->descriptor->bcdUSB);
392 le16_to_cpus(&dev->descriptor->idVendor);
393 le16_to_cpus(&dev->descriptor->idProduct);
394 le16_to_cpus(&dev->descriptor->bcdDevice);
so no additional idVendor/idProduct descriptor fields
le16_to_cpu() conversion is needed after that.
On the big-endian machines extra le16_to_cpu() conversion
leads to wrong idVendor/idProduct USB device parameters values
(e.g. see devinfo <usb-device> output), and to a much more
serious problem: idVendor/idProduct-based USB device detection
does not work.
