Upstream has integrated the Realtek target into the generic MIPS initialization and so MACH_REALTEK_RTL has gained some new features. Especially: - CONFIG_MACH_GENERIC_CORE generates central modules - board-realtek module adds device specific extensions The current downstream initialization works well and upgrading to kernel 6.12 is not the right time to harmonize this. Modify the MACH definitions to the current needs.

Subject: [PATCH] realtek: Create 4 different Realtek Platforms
|
|
|
|
Creates RTL83XX as a basic kernel config parameter for the
|
|
RTL838X, RTL839x, RTL930X and RTL931X platforms with respective
|
|
configurations for the SoCs, which are introduced in addition.
