f82438948f x86: Update Chromium OS GNVS names
The Global Non-Volatile Storage struct has some fields with particular
meanings. Rename these to make things easier to follow. Also add a few
more boot flags.

GNVS should not be confused with GNVQ (Going Nowhere Very Quickly).

37c664e825 x86: Make sure the SPL image ends on a suitable boundary
The part of U-Boot that actually ends up in u-boot-nodtb.bin is not built
with any particular alignment. It ends at the start of the BSS section.
The BSS section selects its own alignment, which may larger.
This means that there can be a gap of a few bytes between the image
ending and BSS starting.

Since u-boot.bin is build by joining u-boot-nodtb.bin and u-boot.dtb (with
perhaps some padding for BSS), the expected result is not obtained. U-Boot
uses the end of BSS to find the devicetree, so this means that it cannot
be found.

Add 32-byte alignment of BSS so that the image size is correct and
appending the devicetree will place it at the end of BSS.

Example SPL output without this patch:

Sections:
Idx Name          Size      VMA       LMA       File off  Algn
  0 .text         000142a1  fef40000  fef40000  00001000  2**4
                  CONTENTS, ALLOC, LOAD, RELOC, READONLY, CODE
  1 .u_boot_list  000014a4  fef542a8  fef542a8  000152a8  2**3
                  CONTENTS, ALLOC, LOAD, RELOC, DATA
  2 .rodata       0000599c  fef55760  fef55760  00016760  2**5
                  CONTENTS, ALLOC, LOAD, RELOC, READONLY, DATA
  3 .data         00000970  fef5b100  fef5b100  0001c100  2**5
                  CONTENTS, ALLOC, LOAD, RELOC, DATA
  4 .binman_sym_table 00000020  fef5ba70  fef5ba70  0001ca70  2**2
                  CONTENTS, ALLOC, LOAD, DATA
  5 .bss          00000060  fef5baa0  fef5baa0  00000000  2**5
                  ALLOC

You can see that .bss is aligned to 2**5 (32 bytes). This is because of
the mallinfo struct in dlmalloc.c:

 17 .bss.current_mallinfo 00000028  00000000  00000000  000004c0  2**5
                  ALLOC

In this case the size of u-boot-spl-nodtb.bin is 0x1ba90. This matches up
with the _image_binary_end symbol:

fef5ba90 g       .binman_sym_table      00000000 _image_binary_end

But BSS starts 16 bytes later, at 0xfef5baa0, due to the 32-byte
alignment. So we must align _image_binary_end to a 32-byte boundary. This
forces the binary size to be 0x1baa0, i.e. ending at the start of bss, as
expected.

Note that gcc reports __BIGGEST_ALIGNMENT__ of 16 on this build, even
though it generates an object file with a member that requests 32-byte
alignment.

The current_mallinfo struct is 40 bytes in size. Increasing the struct to
68 bytes (i.e. just above a 64-byte boundary) does not cause the alignment
to go above 32 bytes. So it seems that 32 bytes is the maximum alignment
at present.

eb5a2b6710 net: sun8i-emac: Determine pinmux based on SoC, not EMAC type
The pinmux choice for the RMII/RGMII pins the EMAC is connected to is
not dependent on the EMAC IP, but on the SoC it is integrated in.
Deriving the pinmux from the DT compatible string (as we do at the
moment) will thus cause problems with certain EMAC IP / SoC combinations.

To avoid this exact issue with the H616, let's use our Kconfig MACH
symbols to choose the correct pinmux setup.

b14e520517 net: sun8i-emac: Always clear syscon EPHY register
At the moment we only consider the EPHY register for those SoCs were
we actually have an internal PHY to configure. However even other SoCs
have this register, an expect the EPHY select bit to be cleared for
proper operation with an external PHY.

Rework sun8i_emac_set_syscon_ephy() to be called regardless of the EMAC
model, and clear the H3_EPHY_SELECT bit if no internal PHY is used.

We get away without it so far because SoCs like the A64 clear this bit
on reset, but we need to explicitly clear it on the H616, for instance.
The Linux driver does so as well.

a764c94128 usb: gadget: OS Feature Descriptors support
This is a proting patch from linux kernel: 37a3a533429e
("usb: gadget: OS Feature Descriptors support"), the original commit
log see below:

There is a custom (non-USB IF) extension to the USB standard:

http://msdn.microsoft.com/library/windows/hardware/gg463182

They grant permission to use the specification - there is
"Microsoft OS Descriptor Specification License Agreement"
under the link mentioned above, and its Section 2 "Grant
of License", letter (b) reads:

"Patent license. Microsoft hereby grants to You a nonexclusive,
royalty-free, nontransferable, worldwide license under Microsoft鈥檚
patents embodied solely within the Specification and that are owned
or licensable by Microsoft to make, use, import, offer to sell,
sell and distribute directly or indirectly to Your Licensees Your
Implementation. You may sublicense this patent license to Your
Licensees under the same terms and conditions."

The said extension is maintained by Microsoft for Microsoft.

Yet it is fairly common for various devices to use it, and a
popular proprietary operating system expects devices to provide
"OS descriptors", so Linux-based USB gadgets whishing to be able
to talk to a variety of operating systems should be able to provide
the "OS descriptors".

This patch adds optional support for gadgets whishing to expose
the so called "OS Feature Descriptors", that is "Extended Compatibility ID"
and "Extended Properties".

Hosts which do request "OS descriptors" from gadgets do so during
the enumeration phase and before the configuration is set with
SET_CONFIGURATION. What is more, those hosts never ask for configurations
at indices other than 0. Therefore, gadgets whishing to provide
"OS descriptors" must designate one configuration to be used with
this kind of hosts - this is what os_desc_config is added for in
struct usb_composite_dev. There is an additional advantage to it:
if a gadget provides "OS descriptors" and designates one configuration
to be used with such non-USB-compliant hosts it can invoke
"usb_add_config" in any order because the designated configuration
will be reported to be at index 0 anyway.

This patch also adds handling vendor-specific requests addressed
at device or interface and related to handling "OS descriptors"."

Define a new 'SCRIPT' type for DFU entities. The downloaded data are
treated as simple u-boot's scripts and executed with run_command_list()
function.

Flashing the 'SCRIPT' entity might result in changing the 'dfu_alt_info'
environment variable from the flashed script, so add a global variable
for tracking the potential need to reinitialize the dfu_alt_info related
structures.

b5f3405b9d dfu: add 'SKIP' entity
Define a new 'SKIP' type for the DFU entities. The flashed data for that
entity is simply ignored without returning any error values.

This allows to have one flashing procedure and images for the different
board types or variants, where each board uses only the images relevant
to it and skips the rest. This is especially usefull for the THOR
protocol, which usually transfers more than one file in a single session.

f21358ad6c dfu: mmc: use the default MMC device if entity specifies it as -1
Use the default MMC device set in the command line if entity specifies it
as -1. This allows to use the same dfu_alt_info string for different MMC
devices (like embedded eMMC and external SD card if data layout is the
same on both devices).

bafdf4caac cmd: bcb: Add support for processing const string literals in bcb_set()
On request/suggestion from Simon Glass back in May 22 2019 [1], the
'strsep' mechanism implemented in bcb_set() was set to work directly
with user-provided argv strings, to avoid duplicating memory and for
the sake of simpler implementation.

However, since we recently exposed bcb_write_reboot_reason() API to be
called by U-Boot fastboot, the idea is to be able to pass const string
literals to this new BCB API, carrying the reboot reason.

Since 'strsep' (just like its older/superseded sibling 'strtok')
modifies the input string passed as parameter, BCB command in its
current state would attempt to perform in-place modifications in a
readonly string, which might lead to unexpected results.

Fix the above with the cost of one dynamic memory allocation ('strdup').
This will also ensure no compiler warnings when passing string literals
to bcb_write_reboot_reason().

e74670adfe cmd: bcb: Expose 'bcb_write_reboot_reason' to external callers
Fastboot is evolving and beginning with commit [1], the
upstream implementation expects bootloaders to offer support for:
 - reboot-recovery
 - reboot-fastboot

The most natural way to achieve the above is through a set of
pre-defined "reboot reason" strings, written into / read from
the BCB "command" field, e.g.:
 - bootonce-bootloader [2]
 - boot-fastboot [3]
 - boot-recovery [4]

Expose the first 'bcb' API meant to be called by e.g. fastboot stack,
to allow updating the BCB reboot reason via the BCB 'command' field.

e2ffb3be49 cmd: bcb: Extract '__bcb_store' from 'do_bcb_store' for internal needs
Enriching the functionality of U-Boot 'bcb' may assume using the
existing sub-commands as building blocks for the next ones.

A clean way to achive the above is to expose a number of static
routines, each mapped to an existing user command (e.g. load/set/store),
with a user/caller-friendly prototype (i.e. do not force the caller
to wrap an integer into a string).

This third patch makes '__bcb_store' available for internal needs.

No functional change intended.
