Both in file_fat_write_at() and fat_mkdir() the incoming file or directory

In file_fat_write_at() the value of the variable basename is assigned to
the filename parameter and afterwards the variable filename is used instead
of basename. It is more readable to use the variable basename and leave
filename unchanged.
In fat_mkdir() the base name variable is called directory. This is

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.

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"."

f_rockusb: Avoid use-after-free in the global pointer variable
In case of usb_add_function() failure the error path has two issues:
- the potentially allocated structure isn't getting freed
- the global pointer variable is assigned to garbage
Fix the above mentioned issues by freeing memory and assigning NULL.

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().
