For version 1 to 3 of the device tree, this is the node full
path as a zero terminated string, starting with "/". The
following equation will not hold, since the node name has
been processed in the fdt_get_name().*pathp == '/'
For version 16 and later, this is the node unit name only
(or an empty string for the root node). So the above
equation will still not hold.So the kbasename() is redundant, just remove it.

Commit 428826f5358c ("fdt: add support for rng-seed") moves of_fdt_crc32
from early_init_dt_verify() to early_init_dt_scan() since
early_init_dt_scan_chosen() may modify fdt to erase rng-seed.However, arm and some other arch won't call early_init_dt_scan(), they
call early_init_dt_verify() then early_init_dt_scan_nodes().Restore of_fdt_crc32 to early_init_dt_verify() then update it in
early_init_dt_scan_chosen() if fdt if updated.Fixes: 428826f5358c ("fdt: add support for rng-seed")

Introducing a chosen node, rng-seed, which is an entropy that can be
passed to kernel called very early to increase initial device
randomness. Bootloader should provide this entropy and the value is
read from /chosen/rng-seed in DT.Obtain of_fdt_crc32 for CRC check after early_init_dt_scan_nodes(),
since early_init_dt_scan_chosen() would modify fdt to erase rng-seed.Add a new interface add_bootloader_randomness() for rng-seed use case.
Depends on whether the seed is trustworthy, rng seed would be passed to
add_hwgenerator_randomness(). Otherwise it would be passed to
add_device_randomness(). Decision is controlled by kernel config

Now that ARM64 uses phys_initrd_start/phys_initrd_size, we can get rid
of its custom __early_init_dt_declare_initrd() which causes a fair
amount of objects rebuild when changing CONFIG_BLK_DEV_INITRD. In order
to make sure ARM64 does not produce a BUG() when VM debugging is turned
on though, we must avoid early calls to __va() which is what
__early_init_dt_declare_initrd() does and wrap this around to avoid
running that code on ARM64.Signed-off-by: Florian Fainelli

When the OF code was originally made common by Grant in commit
51975db0b733 ("of/flattree: merge early_init_dt_scan_memory() common
code") (Feb 2010), the common code inherited a hack to handle
PPC "longtrail" machines, which had a "memory@0" node with no
device_type.That check was then made to only apply to PPC32 in b44aa25d20e2 ("of:
Handle memory@0 node on PPC32 only") (May 2014).But according to Paul Mackerras the "longtrail" machines are long
dead, if they were ever seen in the wild at all. If someone does still
have one, we can handle this firmware wart in powerpc platform code.So remove the hack once and for all.

Commit 99492c39f39f ("earlycon: Fix __earlycon_table stride") tried to fix
__earlycon_table stride by forcing the earlycon_id struct alignment to 32
and asking the linker to 32-byte align the __earlycon_table symbol. This
fix was based on commit 07fca0e57fca92 ("tracing: Properly align linker
defined symbols") which tried a similar fix for the tracing subsystem.However, this fix doesn't quite work because there is no guarantee that
gcc will place structures packed into an array format. In fact, gcc 4.9
chooses to 64-byte align these structs by inserting additional padding
between the entries because it has no clue that they are supposed to be in
an array. If we are unlucky, the linker will assign symbol
"__earlycon_table" to a 32-byte aligned address which does not correspond
to the 64-byte aligned contents of section "__earlycon_table".To address this same problem, the fix to the tracing system was
subsequently re-implemented using a more robust table of pointers approach
by commits:
3d56e331b653 ("tracing: Replace syscall_meta_data struct array with pointer array")
654986462939 ("tracepoints: Fix section alignment using pointer array")
e4a9ea5ee7c8 ("tracing: Replace trace_event struct array with pointer array")Let's use this same "array of pointers to structs" approach for
EARLYCON_TABLE.Fixes: 99492c39f39f ("earlycon: Fix __earlycon_table stride")

memblock_virt_alloc() works for both memblock and bootmem, so use it and
make early_init_dt_alloc_memory_arch a static function. The arches using
bootmem define early_init_dt_alloc_memory_arch as either:__alloc_bootmem(size, align, __pa(MAX_DMA_ADDRESS))
or:
alloc_bootmem_align(size, align)
Both of these evaluate to the same thing as does memblock_virt_alloc for
bootmem. So we can disable the arch specific functions by making
early_init_dt_alloc_memory_arch static and they can be removed in
subsequent commits.Cc: Frank Rowand

For static DT usecases, we don't need the disabled nodes and can skip
unflattening. This saves a significant amount of RAM in memory constrained
cases. In one example on STM32F469, the RAM usage goes from 118K to 26K.There are a few cases in the kernel that modify the status property
dynamically. These all are changes from enabled to disabled, depend on
OF_DYNAMIC or are not FDT based (PDT based).Tested-by: Nicolas Pitre

With dependencies on a statically allocated full path name converted to
use %pOF format specifier, we can store just the basename of node, and
the unflattening of the FDT can be simplified.This commit will affect the remaining users of full_name. After
analyzing these users, the remaining cases should only change some print
messages. The main users of full_name are providing a name for struct
resource. The resource names shouldn't be important other than providing
/proc/iomem names.We no longer distinguish between pre and post 0x10 dtb formats as either
a full path or basename will work. However, less than 0x10 formats have
been broken since the conversion to use libfdt (and no one has cared).
The conversion of the unflattening code to be non-recursive also broke
pre 0x10 formats as the populate_node function would return 0 in that
case.Signed-off-by: Rob Herring

Pull DeviceTree updates from Rob Herring:
- vsprintf format specifier %pOF for device_node's. This will enable us
to stop storing the full node names. Conversion of users will happen
next cycle.- Update documentation to point to DT specification instead of ePAPR.
- Split out graph and property functions to a separate file.
- New of-graph functions for ALSA
- Add vendor prefixes for RISC-V, Linksys, iWave Systems, Roofull,
Itead, and BananaPi.- Improve dtx_diff utility filename printing.
