0d15463c05 dtoc: Rename the phandle struct
Rather than naming the phandle struct according to the number of cells it
uses (e.g. struct phandle_2_cell) name it according to the number of
arguments it has (e.g. struct phandle_1_arg). This is a more intuitive
naming.

c20ee0ed07 dtoc: Add support for 32 or 64-bit addresses
When using 32-bit addresses dtoc works correctly. For 64-bit addresses it
does not since it ignores the #address-cells and #size-cells properties.

Update the tool to use fdt64_t as the element type for reg properties when
either the address or size is larger than one cell. Use the correct value
so that C code can obtain the information from the device tree easily.

Alos create a new type, fdt_val_t, which is defined to either fdt32_t or
fdt64_t depending on the word size of the machine. This type corresponds
to fdt_addr_t and fdt_size_t. Unfortunately we cannot just use those types
since they are defined to phys_addr_t and phys_size_t which use
'unsigned long' in the 32-bit case, rather than 'unsigned int'.

Add tests for the four combinations of address and size values (32/32,
64/64, 32/64, 64/32). Also update existing uses for rk3399 and rk3368
which now need to use the new fdt_val_t type.

According to fsync specification [1] some special files (e.g., a pipe, FIFO,
or socket) don't support synchronization and return either EROFS or EINVAL.

On the linux side the sys_fsync -> do_fsync() checks if the requested file
has f_op->fsync defined. If not it returns EINVAL [2].

This commit prevents writing error messages for files (devices), which
do not support fsync().

3809e30273 Makefile: honor PYTHON configuration properly
On some systems `python` is `python3` (for instance, Archlinux). The
`PYTHON` variable can be used to point to `python2` to have a successful
build.

The use of `PYTHON` is currently limited in the Makefile and needs to be
extended in other places:

First, pylibfdt is required to be a Python 2 binding (binman imports
pylibfdt and is only compatible Python 2), so its setup.py needs to be
called accordingly. An alternative would be to change the libfdt
setup.py shebang to python2, but the binding is actually portable. Also,
it would break on system where there is no such thing as `python2`.

Secondly, the libfdt import checks need to be done against Python 2 as
well since the Python 2 compiled modules (in this case _libdft.so) can
not be imported from Python 3.

Note on the libfdt imports: "@if ! PYTHONPATH=tools $(PYTHON) -c 'import
libfdt'; then..." is probably simpler than the currently sub-optimal
pipe.

e94136bd87 mips-relocs: Fix warning from gcc 6.3
It seems that gcc 6.3 at least is smart enough to warn about the _val
variable being unassigned in the default case in the set_hdr_field()
macro, but not smart enough to figure out that the default case is never
taken. This results in warnings such as the following:

  pfx##hdr32[idx].field = _val;   \
                          ^
 ../tools/mips-relocs.c:51:11: note: _val was declared here
   uint64_t _val;      \
            ^
 ../tools/mips-relocs.c:88:2: note: in expansion of macro set_hdr_field
   set_hdr_field(p, idx, field, val)

 ../tools/mips-relocs.c: In function main:
 ../tools/mips-relocs.c:77:25: warning: _val may be used uninitialized
    in this function [-Wmaybe-uninitialized]

Avoid this by assigning _val = 0 in the default case, and asserting that
we didn't actually hit it for good measure.

For reference gcc 7.1.1 seems to be smart enough to not hit the above
warning without this patch.

703ec9ddf9 MIPS: Stop building position independent code
U-Boot has up until now built with -fpic for the MIPS architecture,
producing position independent code which uses indirection through a
global offset table, making relocation fairly straightforward as it
simply involves patching up GOT entries.

Using -fpic does however have some downsides. The biggest of these is
that generated code is bloated in various ways. For example, function
calls are indirected through the GOT & the t9 register:

  8f998064   lw     t9,-32668(gp)
  0320f809   jalr   t9

Without -fpic the call is simply:

  0f803f01   jal    be00fc04 <puts>

This is more compact & faster (due to the lack of the load & the
dependency the jump has on its result). It is also easier to read &
debug because the disassembly shows what function is being called,
rather than just an offset from gp which would then have to be looked up
in the ELF to discover the target function.

Another disadvantage of -fpic is that each function begins with a
sequence to calculate the value of the gp register, for example:

  3c1c0004   lui    gp,0x4
  279c3384   addiu  gp,gp,13188
  0399e021   addu   gp,gp,t9

Without using -fpic this sequence no longer appears at the start of each
function, reducing code size considerably.

This patch switches U-Boot from building with -fpic to building with
-fno-pic, in order to gain the benefits described above. The cost of
this is an extra step during the build process to extract relocation
data from the ELF & write it into a new .rel section in a compact
format, plus the added complexity of dealing with multiple types of
relocation rather than the single type that applied to the GOT. The
benefit is smaller, cleaner, more debuggable code. The relocate_code()
function is reimplemented in C to handle the new relocation scheme,
which also makes it easier to read & debug.

Taking maltael_defconfig as an example the size of u-boot.bin built
using the Codescape MIPS 2016.05-06 toolchain (gcc 4.9.2, binutils
2.24.90) shrinks from 254KiB to 224KiB.

db7cd4ed33 tools/kwbimage: fix v1 header verification
The verify_header callback in kwbimage.c only verifies v0 headers checksum.
Running 'mkimage -l' on a v1 image gives the following misleading output:

GP Header: Size ae000000 LoadAddr 34160600

Implement support for v1 headers. For that, factor out the header checksum code
to a separate main_hdr_checksum_ok() routine. This routine relies on the fact
that the checksum field offset is the same in both v0 and v1 headers. With this
patch applied 'mkimage -l' correctly identifies the image:

Image Type:   MVEBU Boot from sdio Image
Image version:1
Data Size:    398904 Bytes = 389.55 KiB = 0.38 MiB
Load Address: 007fffc0
Entry Point:  00800000

2ddd85dc34 moveconfig: Allow piping in 'git show --stat' output
It is useful to be able to process only a subset of boards to save time.
Often that subset is defined by the defconfig files in a git commit. This
change allows things like:

   # Build the database
   ./tools.moveconfig.py -b

   # Find some implying configs
   ./tools/moveconfig.py -i CONFIG_X

   # Add some 'imply' statements to Kconfig files
   ./tools/moveconfig.py -i CONFIG_X -a CONFIG_A,CONFIG_B

   # Reprocess the defconfig files to see if we can drop some changes
   git show --stat | ./tools/moveconfig.py -s -d -

   # Update the commit, with fewer defconfig changes
   gii commit -au

Where the commit contains defconfig files, this will reprocess them to
take account of the imply statements that you added.

the SPL payload (i.e. header1 and payload). For RC4-encoded payloads,
the outer header (header0) is checked, but no detection of whether
this is a SD/MMC or SPI formatted payload takes place.

The output of dumpsys now prints the image type (spl_hdr), whether it
is a SD/MMC or SPI image, and the (padded) size of the image:
  $ ./tools/dumpimage -l ./spl.img
  Image Type:   Rockchip RK33 (SD/MMC) boot image
                               ^^^^^^ SD/MMC vs. SPI indication
                         ^^^^ spl_hdr indicated by the image
  Data Size:    79872 bytes

6cbf7eda3c arm: mvebu: kwbimage: inline function to fix use-after-free
image_version_file()'s only use is to return the version number of the
specified image, and it's only called by kwbimage_generate().  This
version function mallocs "image_cfg" and reads the contents of the image
into that buffer.  Before return to its caller it frees the buffer.

After extracting the version, kwb_image_generate() tries to calculate
the header size by calling image_headersz_v1().  This function now
accesses "image_cfg", which has already been freed.

Since image_version_file() is only used by a single function, inline it
into kwbimage_generate() and only free the buffer after it is no longer
needed.  This also improves code readability since the code is mostly
equal to kwbimage_set_header().

7f0ef5a945 sunxi: Store the device tree name in the SPL header
This patch updates the mksunxiboot tool to optionally add
the default device tree name string to the SPL header. This
information can be used by the firmware upgrade tools to
protect users from harming themselves by trying to upgrade
to an incompatible bootloader.

The primary use case here is a non-removable bootable media
(such as NAND, eMMC or SPI flash), which already may have
a properly working, but a little bit outdated bootloader
installed. For example, the user may download or build a
new U-Boot image for "Cubieboard", and then attemept to
install it on a "Cubieboard2" hardware by mistake as a
replacement for the already existing bootloader. If this
happens, the flash programming tool can identify this
problem and warn the user.

The size of the SPL header is also increased from 64 bytes
to 96 bytes to provide enough space for the device tree name
string.

mksunxiboot limits the size of the resulting SPL binaries to pretty
conservative values to cover all SoCs and all boot media (NAND).
It turns out that we have limit checks in place in the build process,
so mksunxiboot can be relaxed and allow packaging binaries up to the
actual 32KB the mask boot ROM actually imposes.
This allows to have a bigger SPL, which is crucial for AArch64 builds.

mkimage to rewrite this word with the 'RK33' boot magic.

This change brings logic to calculate the header size and allocate
the header back in sync. For the RK3399 we now limit the header to
before the payload (i.e. the 'header0' and the padding up to the
actual image) and overwrite the first word (inserted by the
boot0-hook for this purpose) with the 'RK33' magic in-place.

111bcc4fb6 rockchip: mkimage: pad the header to 8-bytes (using a 'nop') for RK3399
The RK3399 boot code (running as AArch64) poses a bit of a challenge
for SPL image generation:
 * The BootROM will start execution right after the 4-byte header (at
   the odd instruction word loaded into SRAM at 0xff8c2004, with the
   'RK33' boot magic residing at 0xff8c2000).
 * The default padding (during ELF generation) for AArch64 is 0x0,
   which is an illegal instruction and the .text section needs to be
   naturally aligned (someone might locate a 64bit constant relative
   to the section start and unaligned loads trigger a fault for all
   privileged modes of an ARMv8)... so we can't simply define the
   CONFIG_SPL_TEXT_BASE option to the odd address (0xff8c2004).
 * Finally, we don't want to change the values used for padding of
   the SPL .text section for all ARMv8 targets to the instruction
   word encoding 'nop', as this would affect all padding in this
   section and might hide errors that would otherwise quickly trigger
   an illegal insn exception.

To deal with this situation, we modify the rkimage generation to
 - understand the fact that the RK3399 needs to pad the header to an
   8 byte boundary using an AArch64 'nop'
 - the necessary logic to adjust the header_size (which controls the
   location where the payload is copied into the image) and to insert
   this padding (AArch64 insn words are always little-endian) into
   the image following the 4-byte header magic.

f3edf8b18f rockchip: mkimage: simplify start/size calculation for rc4_encode
The RC4 encoding works on full blocks, but the calculation of the
starting offset and size are needlessly complicated by using a
reference value known to be offset into a block by the size of the
header and then correcting for the (hard-coded) size of the header
(i.e. 4 bytes).

We change this over to use the RK_SPL_HDR_START directly (which is
known to be on a block boundary).

55bc080e79 dtoc: make ScanTree recurse into subnodes
Previously, dtoc could only process the top-level nodes which led to
device nodes in hierarchical trees to be ignored. E.g. the mmc0 node
in the following example would be ignored, as only the soc node was
processed:

  / {
	soc {
		mmc0 {
			/* ... */
		};
	};
  };

This introduces a recursive helper method ScanNode, which is used by
ScanTree to recursively parse the entire tree hierarchy.

e5caec9a86 Pass empty CFLAGS on invocation of libfdt/setup.py
When building u-boot tools in cross-build environment CFLAGS environment
variable set up for target is taken into an account when building code
for host. Make it empty on invocation of python.

This fixes the following build errors when cross-compiling for xtensa:

  cc1: error: unrecognized command line option "-mlongcalls"
  cc1: error: unrecognized command line option "-mauto-litpools"
