The patch is creating new spl/u-boot-spl-align.bin which is used only
for boot.bin.

Bootrom is not capable to work with non aligned bootloader sizes.
SPL with OF_SEPARATE generates non-align images quite often that's
why this change is required before OF_SEPARATE enableding.

tools: zynqmpimage: round up partition size
The FSBL copies "Total Partition Word Length" * 4 bytes from the boot.bin,
which implies that the partition size is 4 byte aligned. When writing the
partition, mkimage calculates "Total Partition Word Length" by dividing
the size by 4. This implicitly cuts unaligned bytes at the end of the
added binary.
Instead of rounding down, the size must be round up to 4 bytes and the
binary padded accordingly.

imx8mq_evk_defconfig: Move file system options to Kconfig
Chris Spencer reports that when enabling ext4 read support without
also enabling write support the following error is seen:
fs/fs.c:198:12: error: 'ext4_write_file' undeclared here (not in a
function); did you mean 'ext4_read_file'?
.write = ext4_write_file,

Fix this problem by moving these options to Kconfig.

poplar: save environment at a different offset
Change CONFIG_ENV_OFFSET for Poplar to be 1MB further into the eMMC
than before. This puts it immediately prior to the space we are
reserving offset 0x200000-0x400000 for UEFI to save its persistent

sector size, like CONFIG_ENV_OFFSET is.

Revert "fs: fat: assign rootdir sector when accessing root directory"
This particular commit is causing a regression on stih410-b2260 and
other platforms when reading from FAT16. Noting that I had rebased the
original fix from Thomas onto then-current master, there is also
question from Akashi-san if the change is still needed after other FAT
fixes that have gone in.
As reported by Alex Kiernan the above optimization introduces a
regression in the below use case where:
1. Device has defined 'u-boot,dm-spl' property (@ eMMC DTS node)
2. The device downloads its MLO/SPL via UART (not eMMC - the eMMC pinmux
pins are NOT probed/configured in MLO/SPL).
3. The loaded via UART MLO/SPL wants to load Linux from eMMC. In this case
the DM core and pinctrl uclass checks 'u-boot,dm-spl' and don't
configure pins (as it thinks that those were initialized in MLO/SPL).
As we are very close to release - please revert this commit.

The UCLASS_DRIVER for id UCLASS_USB_GADGET_GENERIC needs to be declared
even for platforms that do not enable DM_USB_GADGET. Otherwise the driver
for their usb peripheral controller fails to bind.

dm: usb: udc: Use SEQ_ALIAS to index the USB gadget ports
dfu, fastbot and other usb gadget commands take the USB port index as a
parameter. Currently this index is assigned in the order of the driver
bindings.
Changing this behavior using the SEQ_ALIAS feature. This option assign to
the device a SEQ number based on its alias (if it exists)
To use it we must set the DM_UC_FLAG_SEQ_ALIAS flag and follow the existing
naming convention: use "usb" for the name of the gadget UCLASS_DRIVER
(same as for the UCLASS_USB).
If no alias is provided, then the index falls back to the order in which
the bindings took place.
