powerpc: 8xx: Set SDMA configuration register correcly

2024-04-18T13:47:46+00:00

SDMA configuration register needs to be set up only once and doesn't
belong to drivers. Also, the value to be used is different on mpc885.

So do the init in cpu_init_f() with 0x40 for mpc885 and 0x1 for others.

watchdog: mpc8xxx: Make it generic

2023-04-06T12:47:47+00:00

mpc8xx, mpc83xx and mpc86xx have similar watchdog with almost same
memory registers.

Refactor the driver to get the register addresses from the
device tree and use the compatible to know the prescale factor.

Calculate the watchdog setup value from the provided timeout.

Don't declare it anymore as an HW_WATCHDOG, u-boot will start
servicing the watchdog early enough.

On mpc8xx the watchdog configuration register is also used for
configuring the bus monitor. So add it as an option to the watchdog
when it is mpc8xx. When watchdog is not selected, leave the
configuration of the initial SYPCR from Kconfig.

cyclic: Use schedule() instead of WATCHDOG_RESET()

2022-09-18T08:26:33+00:00

Globally replace all occurances of WATCHDOG_RESET() with schedule(),
which handles the HW_WATCHDOG functionality and the cyclic
infrastructure.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

powerpc: mpc8xx: cleaning up watchdog

2018-04-06T20:30:37+00:00

In preparation of migration to DM watchdog, clean up a bit.

The 8xx watchdog really is a HW watchdog, so declare it as is
then it goes through Kconfig

And the watchdog reset doesn't mind getting interrupted, so
no need to disable interrupts
