Some casts from pointers to uint64_t and back in lio_main.c cause base
gcc on i386 to warn "cast from pointer to integer of different size",
and vice versa. Add additional casts to uintptr_t to suppress these.

lan78xx_eeprom_read just checked for EEPROM presence then called
lan78xx_eeprom_read_raw if present, and had only one caller. Introduce
lan78xx_eeprom_present to check for EEPROM presence, and use it in the

This is used by r334964, which was accidentally committed out-of-order

Differences between LAN7800 and LAN7850 from the driver's perspective:
* The LAN7800 muxes EEPROM signals with LEDs, so LED mode needs to be
disabled when reading/writing EEPROM. The EEPROM is not muxed on the
LAN7850.
* The Linux driver enables automatic duplex and speed detection when
there is no EEPROM, for the LAN7800 only. With this FreeBSD driver
LAN7850-based adapters without a configuration EEPROM fail to link
(with or without the automatic duplex and speed detection code), so
I have just followed the example of the Linux driver for now.

Casting from rman_res_t to a pointer results in "cast to pointer from
integer of different size" warnings with base gcc on i386, so print
these without casting. The kva field of struct bxe_bar is of type
vm_offset_t, which can be 32 or 64 bit, so cast it to uintmax_t before
printing.

Base gcc fails to compile sys/dev/drm2/i915/intel_display.c for i386,
with the following -Werror warnings:
cc1: warnings being treated as errors
/usr/src/sys/dev/drm2/i915/intel_display.c:8884: warning:
initialization from incompatible pointer type
This is due to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=36432, which
incorrectly interprets the [] as a flexible array member.
Because base gcc does not have a -W flag to suppress this particular
warning, it requires a rather ugly cast. To not influence any other
compiler, put it in a #if/#endif block.

If we fail noise floor calibration then we may end up with a deaf NIC
which we can't recover without a full chip reset.
Earlier chips seem to get less stuck in this condition versus AR9280/later
and AR9300/later, but whilst here just fix up the AR5212 era chips to also
return NF calibration failures.
This HAL routine would only return failure if the channel was not configured.
This is a no-op until the driver side code for doing resets and the HAL
code for being told about the reset type (and then handling it!) is
implemented.
Tested:
* AR9280, STA mode
* AR2425, STA mode
* AR9380, STA mode
pmc_process_interrupt takes 5 arguments when only 3 are needed.
cpu is always available in curcpu and inuserspace can always be

While facially a reasonable cleanup this change was motivated

On PowerNV systems, the rootfs is passed through kexec, which loads the rootfs
into memory and set two fdt entries to describe where the file is located in
the memory;
I need to pass this memory region to the md device as a mfs_root, but, current
md driver does not support two things:
* Just getting a pointer from an external (bootloader) memory. If I need to
workaround it, I would need to declare a static array and memcopy from this
external memory to this static variable.
* The size of the image. The usage of mfs_root_end, which is not a pointer,
seems to be not possible for this prestaged scenario.
This patch simply adds a new way to load mfs_root from memory.
