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-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/ Christophe Leroy (9): powerpc/fsl_uli1575: Misc cleanup powerpc/85xx: Rename setup_arch and pic_init on p1023 powerpc/85xx: Remove DBG() macro powerpc/85xx: Remove #ifdefs CONFIG_PCI in mpc85xx_ds powerpc/85xx: mpc85xx_{ds/rdb} compact the call to mpic_alloc() powerpc/85xx: mpc85xx_{ds/rdb} replace BUG_ON() by WARN_ON() powerpc/85xx: mpc85xx_{ds/rdb} replace prink by pr_xxx macro powerpc/85xx: Remove #ifdefs CONFIG_PPC_I8259 in mpc85xx_ds powerpc/85xx: Remove #ifdef CONFIG_QUICC_ENGINE in mpc85xx_rdb Pali Rohár (8): powerpc/85xx: p2020: Move all P2020 DS machine descriptions to p2020.c powerpc/85xx: p2020: Move all P2020 RDB machine descriptions to p2020.c powerpc/85xx: p2020: Move i8259 code into own function powerpc/85xx: mpc85xx_ds: Move PCI code into own file 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/include/asm/ppc-pci.h | 2 + arch/powerpc/platforms/85xx/Kconfig | 22 +++- arch/powerpc/platforms/85xx/Makefile | 5 +- arch/powerpc/platforms/85xx/mpc85xx.h | 12 ++ arch/powerpc/platforms/85xx/mpc85xx_8259.c | 78 ++++++++++++ arch/powerpc/platforms/85xx/mpc85xx_ds.c | 133 ++------------------- arch/powerpc/platforms/85xx/mpc85xx_mds.c | 7 -- arch/powerpc/platforms/85xx/mpc85xx_rdb.c | 79 ++---------- arch/powerpc/platforms/85xx/mpc85xx_uli.c | 64 ++++++++++ arch/powerpc/platforms/85xx/p1023_rdb.c | 8 +- arch/powerpc/platforms/85xx/p2020.c | 95 +++++++++++++++ arch/powerpc/platforms/fsl_uli1575.c | 6 +- 13 files changed, 301 insertions(+), 212 deletions(-) create mode 100644 arch/powerpc/platforms/85xx/mpc85xx_8259.c create mode 100644 arch/powerpc/platforms/85xx/mpc85xx_uli.c create mode 100644 arch/powerpc/platforms/85xx/p2020.c -- 2.39.1
