Besides incorporating feedback on v2 (mainly multi-image support), I've also reinstated code paths needed by the sama5d2, whose port I worked a bit on. This patchset applies on top of v2 of "ARM: at91: misc fixes and cleanup", which I sent out an hour ago. As with v2, it leaves the user the option to select OFDEVICE for the first stage. I haven't managed to get a small enough of-based barebox that still works though. The included defconfig uses board code instead, which makes the MMC first stage fit into 49K. Changes since v2 <20190219172150.11901-1-a.fatoum@pengutronix.de>: - addressed Roland's feedback: commits now indicate where they copy code from if any - SoC-specific get_ddram_size and associated #ifdeffery was removed as suggested by Sascha. This series was rebased on-top. - lowlevel_clock was renamed to at91_pmc_ll because I like that name more - removed instances of IS_ENABLED in generic code for multi-image support. One instance could be inferred from function argument, the rest now accepts a flags parameter. - reinstated sama5d2 specific SDRAM and PMC initialization code as well as necessary register offset definitions - added missing Atmel copyright/disclaimer in the evb's lowlevel.c as requested by Roland. Other files have the Atmel copyright, the disclaimer looks compatible with the newly added LICENSES/BSD-1-Clause - removed board code define for multi-image build support as per Sascha's comment - adjusted code to use the new MAX_PBL_IMAGE_SIZE for indicating maximum first stage bootloader size Changes since v1 <20190116174559.17416-1-a.fatoum@pengutronix.de>: - dropped removal of h32mx code, it was just touched by ARM: at91: microchip-kz9477-evb: support first stage boot and might be useful for future ports - dropped removal of sama5d3_matrix.h, already mainline via f722f2a12 ("ARM: at91: delete unused mach/sama5d3_matrix.h") - added commit with BSD-1-Clause license text - split the migration to the at91bootstrap header for SDRAM defines into 3 separate commits for better comprehension as suggested by Sam - arch-prefixed globally visible functions/defines - copied over some helper functions from at91bootstrap for board init, or moved them to headers, so board code can look more like at91bootstrap board code - moved some helper function into headers, so they can be used in multiple boards in future - replaced all __raw_{read,write}T with {read,write}T - added separate entry point for first stage, like am335x does - added build-time size check for first stage - renamed _first_stage suffix to _bootstrap, for symmetry with the other at91sam9261 - compressed the DTB - added infrastructure for future device tree based first stage - added documentation as suggested by Sam - changed NAND partition layout in board code as suggested by Sascha - stylistic fixes here and there Ahmad Fatoum (15): LICENSES: add BSD-1-Clause license ARM: at91: import at91bootstrap's at91_ddrsdrc.h ARM: at91: migrate at91sam9_ddrsdr.h to use at91bootstrap's at91_ddrsdrc.h ARM: at91: replace at91sam9_ddrsdr.h with at91bootstrap's at91_ddrsdrc.h ARM: at91: watchdog: implement at91_wdt_disable ARM: at91: import lowlevel clock initialization from at91bootstrap ARM: at91: import early_udelay from at91bootstrap ARM: at91: import low level DDRAMC initialization code from at91bootstrap ARM: at91: import lowlevel dbgu UART init code from at91bootstrap images: at91: differentiate between first and second stage images ARM: at91: microchip-ksz9477-evb: use compressed DTB ARM: dts: microchip-ksz9477-evb: add dummy first stage device tree ARM: at91: microchip-ksz9477-evb: implement first stage ARM: at91: microchip-ksz9477: provide board code fallback doc: microchip-ksz9477-evb: add documentation .../boards/at91/microchip-ksz9477-evb.rst | 38 +- LICENSES/other/X11 | 28 + LICENSES/preferred/BSD-1-Clause | 15 + arch/arm/boards/at91sam9m10g45ek/lowlevel.c | 2 +- arch/arm/boards/at91sam9m10ihd/lowlevel.c | 2 +- arch/arm/boards/at91sam9n12ek/lowlevel.c | 2 +- arch/arm/boards/at91sam9x5ek/lowlevel.c | 2 +- .../arm/boards/microchip-ksz9477-evb/Makefile | 3 + arch/arm/boards/microchip-ksz9477-evb/board.c | 127 +++++ .../boards/microchip-ksz9477-evb/lowlevel.c | 213 +++++++- arch/arm/boards/pm9g45/lowlevel.c | 3 +- arch/arm/boards/sama5d3_xplained/lowlevel.c | 2 +- arch/arm/boards/sama5d3xek/lowlevel.c | 2 +- arch/arm/boards/sama5d4_xplained/lowlevel.c | 2 +- arch/arm/boards/sama5d4ek/lowlevel.c | 2 +- ...rochip_ksz9477_evb_bootstrap_mmc_defconfig | 24 + arch/arm/dts/Makefile | 4 +- .../at91-microchip-ksz9477-evb-boot-bin.dts | 13 + arch/arm/mach-at91/Kconfig | 17 +- arch/arm/mach-at91/Makefile | 3 + arch/arm/mach-at91/at91_pmc_ll.c | 184 +++++++ arch/arm/mach-at91/at91sam9g45_devices.c | 2 +- arch/arm/mach-at91/at91sam9g45_reset.S | 8 +- arch/arm/mach-at91/at91sam9n12_devices.c | 2 +- arch/arm/mach-at91/at91sam9x5_devices.c | 2 +- arch/arm/mach-at91/ddramc.c | 507 ++++++++++++++++++ arch/arm/mach-at91/early_udelay.c | 56 ++ arch/arm/mach-at91/include/mach/at91_dbgu.h | 57 +- .../arm/mach-at91/include/mach/at91_ddrsdrc.h | 332 ++++++++++++ arch/arm/mach-at91/include/mach/at91_pmc.h | 32 +- arch/arm/mach-at91/include/mach/at91_pmc_ll.h | 89 +++ arch/arm/mach-at91/include/mach/at91_wdt.h | 16 + .../mach-at91/include/mach/at91sam9_ddrsdr.h | 138 +---- arch/arm/mach-at91/include/mach/ddramc.h | 36 ++ .../arm/mach-at91/include/mach/early_udelay.h | 14 + arch/arm/mach-at91/include/mach/sama5d3.h | 1 + arch/arm/mach-at91/sama5d3_devices.c | 2 +- arch/arm/mach-at91/sama5d4_devices.c | 2 +- images/Makefile.at91 | 17 +- 39 files changed, 1835 insertions(+), 166 deletions(-) create mode 100644 LICENSES/other/X11 create mode 100644 LICENSES/preferred/BSD-1-Clause create mode 100644 arch/arm/boards/microchip-ksz9477-evb/board.c create mode 100644 arch/arm/configs/microchip_ksz9477_evb_bootstrap_mmc_defconfig create mode 100644 arch/arm/dts/at91-microchip-ksz9477-evb-boot-bin.dts create mode 100644 arch/arm/mach-at91/at91_pmc_ll.c create mode 100644 arch/arm/mach-at91/ddramc.c create mode 100644 arch/arm/mach-at91/early_udelay.c create mode 100644 arch/arm/mach-at91/include/mach/at91_ddrsdrc.h create mode 100644 arch/arm/mach-at91/include/mach/at91_pmc_ll.h create mode 100644 arch/arm/mach-at91/include/mach/ddramc.h create mode 100644 arch/arm/mach-at91/include/mach/early_udelay.h -- 2.20.1 _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
