Commit Message

Moteen Shah July 17, 2026, 8:35 a.m. UTC 
Add a standalone initramfs-module-netsetup recipe that installs
83-netsetup, an initramfs-framework module that configures the network
interface via DHCP before the NFS root mount. The recipe's RDEPENDS
pulls in CPSW and its dependencies, so the kernel modules and DHCP
client are only included when NFS boot support is needed.

Include initramfs-module-netsetup in packagegroup-ti-core-initramfs
gated on :bsp-next, where AM65_CPSW_NUSS became a loadable module.
TI staging kernels (6.6/6.12/6.18) still have CPSW built-in (=y).

Signed-off-by: Moteen Shah <m-shah@ti.com>
---
Changes in v5:
- Scope CPSW modules and netsetup inclusion to :k3:bsp-next to avoid
  breaking legacy non-K3 platforms building with bsp-next (Denys)
- Restore PACKAGE_ARCH = "${MACHINE_ARCH}" since recipe has
  K3-specific RDEPENDS (Denys)
