[PATCH v2 00/20] ARM: K3 updates

[Sascha Hauer <s.hauer@pengutronix.de>]

This series has some updates for the TI K3 architecture.

We add support for bootstrapping boards via USB DFU. This has been sent
earlier, this time booting from eMMC is added as well.

On K3 SoCs we need a bunch of images after the first stage has been
loaded: OP-TEE, ti-dm firmware, TF-A binary and finally a barebox
binary. Until now these are expected as distinct images on the SD cards
FAT partition. This is impractical for booting from eMMC boot partitions
and also DFU boot, so this series adds support for handling a FIP image
containing these binaries.

Also some misc patches like enabling the 32k crystal needed for accurate
RTC frequency

Changes in v2:
- Improve existing FIP code and use it instead of open coding parsing the
  FIP image
- add defconfig file for k3-r5
- Cleanup the board entry functions for the K3 Boards
- Link to v1: https://lore.kernel.org/r/20250205-k3-emmc-v1-0-06679246be41@pengutronix.de
