| |
This patch series unifies all P2020 boards and machine descriptions into one generic unified P2020 machine description. With this generic machine description, kernel can boot on any P2020-based board with correct DTS file.
Tested on CZ.NIC Turris 1.1 board with has Freescale P2020 processor. Kernel during booting correctly detects P2020 and prints: [ 0.000000] Using Freescale P2020 machine description
Changes in v4: * Added several preparatory cleanup patchs * Minimised churn by not duplicating helpers at the first place * Split main patch in two * Dropped patchs 1 and 2 * Untested beyond basic build test
Changes in v3: * Use 'if (IS_ENABLED(CONFIG_PPC_I8259))' instead of '#ifdef CONFIG_PPC_I8259' * Simplify p2020_probe() * Patches generated by -M and -C git options
Link to v2: https://lore.kernel.org/linuxppc-dev/20221224211425.14983-1-pali@kernel.org/
Changes in v2: * Added patch "p2020: Move i8259 code into own function" (separated from the next one) * Renamed CONFIG_P2020 to CONFIG_PPC_P2020 * Fixed descriptions
