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 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-p...@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 Link to v1: https://lore.kernel.org/linuxppc-dev/20220819191557.28116-1-p...@kernel.org/ Pali Rohár (8): powerpc/85xx: Mark mpc85xx_rdb_pic_init() as static powerpc/85xx: Mark mpc85xx_ds_pic_init() as static powerpc/85xx: p2020: Move all P2020 machine descriptions to p2020.c powerpc/85xx: p2020: Move i8259 code into own function powerpc/85xx: p2020: Unify .setup_arch and .init_IRQ callbacks powerpc/85xx: p2020: Define just one machine description powerpc/85xx: p2020: Enable boards by new config option CONFIG_PPC_P2020 powerpc: dts: turris1x.dts: Remove "fsl,P2020RDB-PC" compatible string arch/powerpc/boot/dts/turris1x.dts | 2 +- arch/powerpc/platforms/85xx/Kconfig | 22 ++- arch/powerpc/platforms/85xx/Makefile | 1 + arch/powerpc/platforms/85xx/mpc85xx_ds.c | 25 +--- arch/powerpc/platforms/85xx/mpc85xx_rdb.c | 46 +----- .../platforms/85xx/{mpc85xx_ds.c => p2020.c} | 135 ++++++------------ 6 files changed, 68 insertions(+), 163 deletions(-) copy arch/powerpc/platforms/85xx/{mpc85xx_ds.c => p2020.c} (52%) -- 2.20.1
