sandbox: Drop video-sync in serial driver

2024-07-31T14:56:06+00:00

With sandbox, when U-Boot is waiting for input it syncs the video
display, since presumably the user has finished typing.

Now that cyclic is used for video syncing, we can drop this. Cyclic
will automatically call the video_idle() function when idle.

Merge patch series "mediatek: cumulative trivial fix for OF_UPSTREAM support"

2024-07-08T17:56:59+00:00

Christian Marangi  says:

This is an initial series that have all the initial trivial
fixes required for usage of OF_UPSTREAM for the mediatek SoC

This also contains the pcie-gen3 driver and the required tphy
support driver to make it work.

Subsequent series will follow with conversion of the mtk-clk
to permit usage of OF_UPSTREAM and upstream clk ID.

MT7981, MT7986 and MT7988 migration to upstream clock ID
is complete and working on MT7623.

Series CI tested with PR: https://github.com/u-boot/u-boot/pull/590

serial: mediatek: add special handling for highspeed and linux compat

2024-07-08T17:45:50+00:00

Upstream linux serial driver use a different logic to setup serial regs.

They have 2 interval:
- < 115200 we use lowspeed regs and 16 * baud
- >= 115200 we use highspeed

We currently use force_highspeed property to force usage of highspeed
regs even with low baud rate.

Add special handling if the upstream compatible is used where we just
apply the same interval with anything >= 115200 in highspeed simulating
force_highspeed.

Merge patch series "xtensa: Enable qemu-xtensa board"

2024-07-04T22:11:08+00:00

Jiaxun Yang  says:

Hi all,

This series enabled qemu-xtensa board.

For dc232b CPU it needs to be built with toolchain[1].

This is a side product of me investigating architectures
physical address != virtual address in U-Boot. Now we can
get it covered under CI and regular tests.

VirtIO devices are not working as expected, due to U-Boot's
assumption on VA == PA everywhere, I'm going to get this fixed
later.

My Xtensa knowledge is pretty limited, Xtensa people please
feel free to point out if I got anything wrong.

Thanks

drivers: serial: Add xtensa semihosting driver

2024-07-04T22:08:37+00:00

Add xtensa semihosting driver.

It can't use regular semihosting driver as Xtensa's has it's own
semihosting ABI.
