## Errors
### SWIOTLB Buffer
> OF: reserved mem: failed to allocate memory for node
> …
> Can not allocate SWIOTLB buffer earlier and can't now provide you with the
> DMA bounce buffer
Ensure `start_x=1` is in `config.txt` and `start_file`/`fixup_file` are not
specified.
### U-Boot: Overwrite Reserved Memory
> ** Reading file would overwrite reserved memory **
Set `CONFIG_LMB_MAX_REGIONS=16` in `u-boot/.config`

Subject: [PATCH] ARM: dts: bcm283x: add compatible picked up by U-Boot
Without brcm,bcm2835-pl011 in compatible U-Boot uses the regular PL011
driver which seems to crash when enable_uart=1 is not used. Using
brcm,bcm2835-pl011 works around that and does not affect Linux since its
not using that compatible string.

Subject: [PATCH] drivers: bcm283x: don't explicitly disable init
It seems that the reason why init doesn't succeed is the lack of clock
support in U-Boot. Setting the default clock of 48MHz for the PL011
UARTs makes reinitialization work consistently.
Note that for the first UART the "skip-init" is anyways set in the
device tree. This will only affect probing of UARTs not enabled by
firmware.

Subject: [PATCH] drivers: bcm283x: allow to spawn any PL011 UART
The current code checks pinmux for the first PL011 only. Raspberry Pi 4
has multiple PL011 UARTs. This code prevents probing of other UARTs in
case the first PL011 UART is not active.
Furthermore, U-Boot supports pinmuxing, hence the pins should be muxed
at this point anyway. Drop the check entirly.
This allows to use other UARTs as stdout paths (e.g. stdout-path =
"serial5:115200n8").

Subject: [PATCH] Revert "nvme: Correct the prps per page calculation method"
This reverts commit 859b33c948945f7904f60a2c12a3792d356d51ad.
If there is more than one PRP List the last entry is a pointer to
the next list. From the NVM Express specification:
"The last entry within a memory page, as indicated by the memory page
size in the CC.MPS field, shall be a PRP List pointer if there is more
than a single memory page of data to be transferred."
For the purpose of calculating the number of pages required for PRP
lists we should always assume that the last entry is required for
the next PRP list.

Subject: [PATCH] usb: xhci-brcm: Make driver compatible with downstream device
tree
The downstream device tree uses just "generic-xhci" as compatible
string. Use this string to make U-Boot work with the downstream Kernel.

Subject: [PATCH] nvme: Use pointer for CPU addressed buffers
Pass buffers which use CPU addressing as void pointers. This aligns with
DMA APIs which use void pointers as argument. It will avoid unnecessary
type casts when adding support bus address translations.

Subject: [PATCH] nvme: translate virtual addresses into the bus's address
space
So far we've been content with passing physical/CPU addresses when
configuring memory addresses into NVMe controllers, but not all
platforms have buses with transparent mappings. Specifically the
Raspberry Pi 4 might introduce an offset to memory accesses incoming
from its PCIe port.
Introduce nvme_virt_to_bus() and nvme_bus_to_virt() to cater with these
limitations, and make sure we don't break non DM users.
For devices where PCIe's view of host memory doesn't match the memory
as seen by the CPU.
A similar change has been introduced for XHCI controller with
commit 1a474559d90a ("xhci: translate virtual addresses into the bus's
address space").
