f40a31e695 sandbox: eth-raw: Add a SIMPLE_BUS to enumerate host interfaces
Ask the OS for each of its interfaces and for each one, bind a U-Boot
device and then probe it. This will allocate the priv data structure

7e21fbca26 efi_loader: Rename sections to allow for implicit data
Some times gcc may generate data that is then used within code that may
be part of an efi runtime section. That data could be jump tables,
constants or strings.

In order to make sure we catch these, we need to ensure that gcc emits
them into a section that we can relocate together with all the other
efi runtime bits. This only works if the -ffunction-sections and
-fdata-sections flags are passed and the efi runtime functions are
in a section that starts with ".text".

Up to now we had all efi runtime bits in sections that did not
interfere with the normal section naming scheme, but this forces
us to do so. Hence we need to move the efi_loader text/data/rodata
sections before the global *(.text*) catch-all section.

With this patch in place, we should hopefully have an easier time
to extend the efi runtime functionality in the future.

507cef3d15 test: dm: Fix wrong aliases property names
After importing v4.17-rc1 Linux commit 9130ba884640 ("scripts/dtc:
Update to upstream version v1.4.6-9-gaadd0b65c987"), sandbox build
reports below warnings:

arch/sandbox/dts/test.dtb: Warning (alias_paths): /aliases: aliases property name must include only lowercase and '-'
arch/sandbox/dts/test.dtb: Warning (alias_paths): /aliases: aliases property name must include only lowercase and '-'
arch/sandbox/dts/test.dtb: Warning (alias_paths): /aliases: aliases property name must include only lowercase and '-'
arch/sandbox/dts/test.dtb: Warning (alias_paths): /aliases: aliases property name must include only lowercase and '-'

Silent them by applying the 's/_/-/' substitution in the names of the
'fdt_dummy0', 'fdt_dummy1', 'fdt_dummy2', 'fdt_dummy3' properties.

Similar DTC warnings have been recently fixed in Linux kernel, e.g. via
v4.17-rc1 commit d366c30d19f4 ("ARM: dts: STi: Fix aliases property name
for STi boards").

If done alone, the DTS update generates a failure of the
`ut dm fdt_translation` unit test in sandbox environment as seen below:

$ ./u-boot -d arch/sandbox/dts/test.dtb
---<-snip->---
=> ut dm fdt_translation
Test: dm_test_fdt_translation: test-fdt.c
test/dm/test-fdt.c:444, dm_test_fdt_translation(): 0 == uclass_find_device_by_seq(UCLASS_TEST_DUMMY, 0, 1, &dev): Expected 0, got -19

Failures: 2
---<-snip->---

Fix this issue in place, by updating the "name" string in the
UCLASS_DRIVER(fdt_dummy) definition, so that it matches the newly
updated aliases properties. After that, the test passes:

$ ./u-boot -d arch/sandbox/dts/test.dtb
---<-snip->---
=> ut dm fdt_translation
Test: dm_test_fdt_translation: test-fdt.c
Test: dm_test_fdt_translation: test-fdt.c (flat tree)

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

e8d5291824 core: ofnode: Fix translation for #size-cells == 0
Commit 286ede6 ("drivers: core: Add translation in live tree case") made
dev_get_addr always use proper bus translations for addresses read from
the device tree. But this leads to problems with certain busses, e.g.
I2C busses, which run into an error during translation, and hence stop
working.

It turns out that of_translate_address() and fdt_translate_address()
stop the address translation with an error when they're asked to
translate addresses for busses where #size-cells == 0 (comment from
drivers/core/of_addr.c):

 * Note: We consider that crossing any level with #size-cells == 0 to mean
 * that translation is impossible (that is we are not dealing with a value
 * that can be mapped to a cpu physical address). This is not really specified
 * that way, but this is traditionally the way IBM at least do things

To fix this case, we check in both the live-tree and non-live tree-case,
whether the bus of the device whose address is about to be translated
has size-cell size zero. If this is the case, we just read the address
as a plain integer and return it, and only apply bus translations if the
size-cell size if greater than zero.

	Missing property '#gpio-cells' in node /reset-ctl or bad phandle
	(referred from /extra-gpios:num-gpios[0])

e2bc87d41c sandbox: Fix comparison of unsigned enum expression warning
In os_dirent_get_typename() we are checking that type falls within the
known values of the enum os_dirent_t.  With clang-3.8 testing this value
as being >= 0 results in a warning as it will always be true.  This
assumes of course that we are only given valid data.  Given that we want
to sanity check the input, we change this to check that it falls within
the range of the first to the last entry in the given enum.

e48eeb9ea3 dm: blk: Improve block device claiming
The intention with block devices is that the device number (devnum field
in its descriptor) matches the alias of its parent device. For example,
with:

	aliases {
		mmc0 = "/sdhci@700b0600";
		mmc1 = "/sdhci@700b0400";
	}

we expect that the block devices for mmc0 and mmc1 would have device
numbers of 0 and 1 respectively.

Unfortunately this does not currently always happen. If there is another
MMC device earlier in the driver model data structures its block device
will be created first. It will therefore get device number 0 and mmc0
will therefore miss out. In this case the MMC device will have sequence
number 0 but its block device will not.

To avoid this, allow a device to request a device number and bump any
existing device number that is using it. This all happens during the
binding phase so it is safe to change these numbers around. This allows
device numbers to match the aliases in all circumstances.

Add a test to verify the behaviour.

135aa95002 clk: convert API to match reset/mailbox style
The following changes are made to the clock API:
* The concept of "clocks" and "peripheral clocks" are unified; each clock
  provider now implements a single set of clocks. This provides a simpler
  conceptual interface to clients, and better aligns with device tree
  clock bindings.
* Clocks are now identified with a single "struct clk", rather than
  requiring clients to store the clock provider device and clock identity
  values separately. For simple clock consumers, this isolates clients
  from internal details of the clock API.
* clk.h is split so it only contains the client/consumer API, whereas
  clk-uclass.h contains the provider API. This aligns with the recently
  added reset and mailbox APIs.
* clk_ops .of_xlate(), .request(), and .free() are added so providers
  can customize these operations if needed. This also aligns with the
  recently added reset and mailbox APIs.
* clk_disable() is added.
* All users of the current clock APIs are updated.
* Sandbox clock tests are updated to exercise clock lookup via DT, and
  clock enable/disable.
* rkclk_get_clk() is removed and replaced with standard APIs.

Buildman shows no clock-related errors for any board for which buildman
can download a toolchain.

test/py passes for sandbox (which invokes the dm clk test amongst
others).

tree reset bindings; i.e. the equivalent of the Linux kernel's reset API.
This controls resets to individual HW blocks or external chips with reset
signals. It doesn't make sense to merge the two APIs into one since they
have different semantic purposes. Resolve the naming conflict by renaming
the existing reset API to sysreset instead, so the new reset API can be
called just reset.

- VAL2OMREG(mode id)
Both defined in file:
