- Ainol_AW1_defconfig / sun7i-a20-ainol-aw1

because VBUS is always enabled:

sunxi: binman: Fix U-Boot offset when SPL is not 32 KiB
On sunxi boards, SPL looks for U-Boot at a 32 KiB offset, unless SPL is
larger than 32 KiB, in which case U-Boot immediately follows SPL. See
the logic in spl_mmc_get_uboot_raw_sector() and spl_spi_load_image().
In two cases, the existing binman description mismatches the SPL code.
For 64-bit boards, binman would place U-Boot immediately following SPL,
even if SPL is smaller than 32 KiB. This can happen when SPL MMC support
is disabled (i.e. when booting from SPI flash).
In contrast, for 32-bit boards, binman would place U-Boot at 32 KiB,
even if SPL is larger than that. This happens because the 'offset'
property does not consider the size of previous entries.
Fix both issues by setting a minimum size for the SPL entry, which
exactly matches the logic in the SPL code. Unfortunately, this size must
be provided as a magic number, since none of the relevant config symbols
(SPL_PAD_TO, SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR, and SYS_SPI_U_BOOT_OFFS)
are guaranteed to be defined in all cases.

Adding block storage emulation for NVM XIP flash devices.
Some paltforms such as Corstone-1000 need to see NVM XIP raw flash
as a block storage device with read only capability.
Here NVM flash devices are devices with addressable
memory (e.g: QSPI NOR flash).
The NVM XIP block storage emulation provides the following features:
- Emulate NVM XIP raw flash as a block storage device with read only capability
- Being generic by design and can be used by any platform
- Device tree node
- Platforms can use multiple NVM XIP devices at the same time by defining a
DT node for each one of them
- A generic NVMXIP block driver allowing to read from the XIP flash
- A generic NVMXIP Uclass driver for binding the block device
- A generic NVMXIP QSPI driver
- Implemented on top of memory-mapped IO (using readq macro)
- Enabling NVMXIP in sandbox64
- A sandbox test case
- Enabling NVMXIP in Corstone1000 platform as a use case
For more details please refer to doc/develop/driver-model/nvmxip.rst
The device associated with this driver is the parent of the blk#<id> device
nvmxip_qspi can be reused by other platforms. If the platform
has custom settings to apply before using the flash, then the platform
can provide its own parent driver belonging to UCLASS_NVMXIP and reuse
nvmxip-blk driver. The custom driver can be implemented like nvmxip_qspi in
addition to the platform custom settings.
Platforms can use multiple NVM XIP devices at the same time by defining a
DT node for each one of them.

to understand what's going on
ARM ARM in section D13.2.41 states that FAR_EL2 will contain meanfull
value in case of ESR.EC holds 0x20, 0x21, 0x24, 0x25, 0x22, 0x34 or
0x35. Same applies for EL1.
This patch adds function whivh determine current EL, gets correct FAR
register and prints it on panic.

vexpress64: Enable VIRTIO_MMIO and RTC_PL031 in the base model
The Arm EBBR (Embedded Base Boot Requirements) require that the time
and basic networking EFI interfaces are available and working, so long
as the hardware has an RTC and network interface.
Arm FVPs typically have a memory-mapped PL031 RTC and a VIRTIO_NET
device defined in the device tree, so "imply" these in the Kconfig for
the FVP base model to simplify creating EBBR-compliant firmware.

vexpress64: Use OF_HAS_PRIOR_STAGE for BASE_FVP variant
BASE_FVP now typically uses a devicetree provided by a prior boot stage
(typically Arm TF-A), so imply this option by default when
TARGET_VEXPRESS64_BASE_FVP is selected.
OF_HAS_PRIOR_STAGE selects OF_BOARD so this change is minor, but aligns
TARGET_VEXPRESS64_BASE_FVP with TARGET_VEXPRESS64_BASER_FVP.

arch: mach-k3: j721s2_init: Disable the firewalls
Some firewalls enabled by ROM are still left on. So some
address space is inaccessible to the bootloader. For example,
in OSPI boot mode we get an exception and the system hangs.
Therefore, disable all the firewalls left on by the ROM.

arm64: Use level-2 for largest block mappings when FEAT_HAFDBS is present
In order to make invalidation by VA more efficient, set the largest
block mapping to 2MB, mapping it onto level-2. This has no material
impact on u-boot's runtime performance, and allows a huge speedup
when cleaning the cache.

arm64: Use FEAT_HAFDBS to track dirty pages when available
Some recent arm64 cores have a facility that allows the page
table walker to track the dirty state of a page. This makes it
really efficient to perform CMOs by VA as we only need to look
at dirty pages.

These patches will use bounce buffers when VIRTIO_F_IOMMU_PLATFORM
feature is in a virtio device.
This feature can be tested with qemu with -device virtio-iommu-pci. So
that when a -device virtio-blk-pci with iommu_platform=true, it will
uses the bounce buffer instead.

virtio: Use bounce buffers when VIRTIO_F_IOMMU_PLATFORM is set

When handling virtio descriptors for such a device, use bounce
buffers to ensure that the underlying buffers are always aligned
to and padded to PAGE_SIZE in preparation for platform specific
handling at page granularity.
