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 which has Freescale P2020 processor. Kernel during booting correctly detects P2020 and prints: [ 0.000000] Hardware name: Turris 1.1 e500v2 0x80211051 Freescale P2020 This patch series depends on another patch series "powerpc/fsl_uli1575: Cleanups": https://lore.kernel.org/linuxppc-dev/20230408132151.8902-1-pali@kernel.org/t/#u (it was split from this one in v5) Changes in v5: * Split fsl_uli1575 patches to separate patch series as this one started to be too big. * Fix commit messages * Reduce includes * Rebase on top of powerpc/next (b0bbe5a2915201e3231e788d716d39dc54493b03) * Test all patches again on CZ.NIC Turris 1.1 board with P2020 processor 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 Link to v1: https://lore.kernel.org/linuxppc-dev/20220819191557.28116-1-pali@kernel.org/ Christophe Leroy (6): powerpc/85xx: Remove DBG() macro 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 (7): 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: mpc85xx_ds: Move i8259 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/platforms/85xx/Kconfig | 22 +++++- arch/powerpc/platforms/85xx/Makefile | 4 +- arch/powerpc/platforms/85xx/mpc85xx.h | 6 ++ arch/powerpc/platforms/85xx/mpc85xx_8259.c | 63 ++++++++++++++++ arch/powerpc/platforms/85xx/mpc85xx_ds.c | 87 +++------------------- arch/powerpc/platforms/85xx/mpc85xx_mds.c | 7 -- arch/powerpc/platforms/85xx/mpc85xx_rdb.c | 63 +++------------- arch/powerpc/platforms/85xx/p2020.c | 81 ++++++++++++++++++++ 9 files changed, 191 insertions(+), 144 deletions(-) create mode 100644 arch/powerpc/platforms/85xx/mpc85xx_8259.c create mode 100644 arch/powerpc/platforms/85xx/p2020.c -- 2.20.1
