board: Rename uclass to sysinfo

2020-11-06T02:18:20+00:00

This uclass is intended to provide a way to obtain information about a
U-Boot board. But the concept of a U-Boot 'board' is the whole system,
not just one circuit board, meaning that 'board' is something of a
misnomer for this uclass.

In addition, the name 'board' is a bit overused in U-Boot and we want to
use the same uclass to provide SMBIOS information.

The obvious name is 'system' but that is so vague as to be meaningless.
Use 'sysinfo' instead, since this uclass is aimed at providing information
on the system.

Rename everything accordingly.

Note: Due to the patch delta caused by the symbol renames, this patch
shows some renamed files as being deleted in one place and created in
another.

timer: Return count from timer_ops.get_count

2020-10-22T13:54:53+00:00

No timer drivers return an error from get_count. Instead of possibly
returning an error, just return the count directly.

common: Move interrupt functions into a new header

2019-12-02T23:25:00+00:00

These functions do not use driver model but are fairly widely used in
U-Boot. But it is not clear that they will use driver model anytime soon,
so we don't want to label them as 'legacy'.

Move them to a new irq_func.h header file. Avoid the name 'irq.h' since it
is widely used in U-Boot already.

timer: Remove DM_FLAG_PRE_RELOC flag in various drivers

2018-11-14T17:16:28+00:00

When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be
bound before relocation. However due to a bug in the DM core,
the flag only takes effect when devices are statically declared
via U_BOOT_DEVICE(). This bug has been fixed recently by commit
"dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in
lists_bind_fdt()", but with the fix, it has a side effect that
all existing drivers that declared DM_FLAG_PRE_RELOC flag will
be bound before relocation now. This may expose potential boot
failure on some boards due to insufficient memory during the
pre-relocation stage.

To mitigate this potential impact, the following changes are
implemented:

- Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver
  only supports configuration from device tree (OF_CONTROL)
- Keep DM_FLAG_PRE_RELOC flag in the driver only if the device
  is statically declared via U_BOOT_DEVICE()
- Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for
  drivers that support both statically declared devices and
  configuration from device tree
