0cad2aa2dd Pass pointers to info parsed from notes, to brandinfo->header_supported filter.
Currently, we parse notes for the values of ELF FreeBSD feature flags
and osrel.  Knowing these values, or knowing that image does not carry
the note if pointers are NULL, is useful to decide which ABI variant
(brand) we want to activate for the image.

Right now this is only a plumbing change

852d135791 aw_cir: lower activation threshold to support NECx protocol
In NECx the leading mark has length of 8T as opposed to 16T in NEC,
where T is  562.5 us.  So, 4.5 ms.
Our threshold was set to 128 * 42.7 us (derived from the sampling
frequency of 3/128 MHz).  So, ~5.5 ms.

The new threshold is set to AW_IR_L1_MIN.  I think that's a good enough
lower bound for detecting the leading pulse.

Also, calculations of active_delay (which is activation delay) are fixed.
Previously they would be wrong if AW_IR_ACTIVE_T was anything but zero,
because the value was already bit-shifted.

Finally, I am not sure why the activation delay was divided by two when
calculating the initial pulse length.  I have not found anything that
would explain or justify it.  So, I removed that division.

Re-implement clocks for these SoC by using now standard extres/clk framework.
This is necessary for future expansion of these. The new  implementation
is (due to the size of the patch) only the initial (minimum) version.
It will be updated/expanded with a subsequent set of particular patches.

This patch is also not tested on OMAP4 based boards (BeagleBone),

40b664f64b [PowerPC] More relocation fixes
It turns out relocating the symbol table itself can cause issues, like fbt
crashing because it applies the offsets to the kernel twice.

This had been previously brought up in rS333447 when the stoffs hack was
added, but I had been unaware of this and reimplemented symtab relocation.

Instead of relocating the symbol table, keep track of the relocation base
in ddb, so the ddb symbols behave like the kernel linker-provided symbols.

This is intended to be NFC on platforms other than PowerPC, which do not
use fully relocatable kernels. (The relbase will always be 0)

 * Remove the rest of the stoffs hack.
 * Remove my half-baked displace_symbol_table() function.
 * Extend ddb initialization to cope with having a relocation offset on the
   kernel symbol table.
 * Fix my kernel-as-initrd hack to work with booke64 by using a temporary
   mapping to access the data.
 * Fix another instance of __powerpc__ that is actually RELOCATABLE_KERNEL.
 * Change the behavior or X_db_symbol_values to apply the relocation base
   when updating valp, to match link_elf_symbol_values() behavior.

852c303b61 copystr(9): Move to deprecate (attempt #2)
This reapplies logical r360944 and r360946 (reverting r360955), with fixed
copystr() stand-in replacement macro.  Eventually the goal is to convert
consumers and kill the macro, but for a first step it helps if the macro is
correct.

Prior commit message:

Unlike the other copy*() functions, it does not serve to copy from one
address space to another or protect against potential faults.  It's just
an older incarnation of the now-more-common strlcpy().

Add a coccinelle script to tools/ which can be used to mechanically
convert existing instances where replacement with strlcpy is trivial.
In the two cases which matched, fuse_vfsops.c and union_vfsops.c, the
code was further refactored manually to simplify.

Replace the declaration of copystr() in systm.h with a small macro
wrapper around strlcpy (with correction from brooks@ -- thanks).

Remove N redundant MI implementations of copystr.  For MIPS, this
entailed inlining the assembler copystr into the only consumer,
copyinstr, and making the latter a leaf function.
