cpu: imx: fix the CPU type field width

2024-08-02T18:16:51+00:00

Increase one more bit to cover all CPU types. Otherwise it shows
wrong CPU info on some platforms, such as i.MX8M Plus:

    U-Boot 2024.04+g674440bc73e+p0 (Jun 06 2024 - 10:05:34 +0000)

cpu: imx: fix the CPU frequency in cpu_imx_get_info()

2024-08-02T18:16:51+00:00

The cpu_freq stores the current CPU frequency in Hz.

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

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

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

I'm actually just using it to get cpu clock frequency.

Merge patch series "Clean-up patch set for MbedTLS integration"

2024-05-22T14:55:35+00:00

Raymond Mao  says:

This patch set is picked from the previously posted serie:
"[RFC] Integrate MbedTLS v3.6 LTS with U-Boot"

They are not directly related to MbedTLS integration, but the
prerequisite for a few clean-up, refactoring and minor fixes.

For V2, the linker script patch is dropped and added one patch
to move the snprintf to stdio.h
