From mboxrd@z Thu Jan 1 00:00:00 1970 From: Weijie Gao Date: Tue, 21 Jan 2020 16:17:54 +0800 Subject: [PATCH v3 00/20] Refactor the architecture parts of mt7628 Message-ID: <1579594674-6665-1-git-send-email-weijie.gao@mediatek.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de This patch series are divided into two parts: The main part is to rewrite the whole architecture code of mt7628: * Lock parts of the d-cache for initial stack so the rest of the code can be reimplemented in C. * Memory controller & DDR initialization have been fully written to support detecting DDR size automatically. * DDR calibration has also been reimplemented with a clear logic. * Implemented a new sysreset driver to take advantage of the reset controller so we can drop the use of syscon-based sysreset to reduce size. The second part is to add SPL support for mt7628: * With SPL enabled we can build the ROM-bootable and RAM-bootable binary simultaneously, and we can drop RAM boot related configs and defconfig files. * Generate compressed u-boot.bin image for SPL to reduce size of final combined binary. * Enable DM support for SPL for a more flexible device probing. * Add a demo board (mt7628_rfb) aims at router application. Changes since v2: * Dropped a patch which removes unused parts of mt7628a.dtsi * Move lzma decompression support to common spl_nor.c * Move u-boot,dm-pre-reloc to u-boot-mt7628.dtsi Makefile | 22 ++ arch/mips/Kconfig | 66 ++++ arch/mips/cpu/start.S | 16 +- arch/mips/cpu/u-boot-spl.lds | 4 +- arch/mips/dts/Makefile | 1 + arch/mips/dts/mediatek,mt7628-rfb.dts | 67 ++++ arch/mips/dts/mt7628-u-boot.dtsi | 56 +++ arch/mips/dts/mt7628a.dtsi | 17 +- arch/mips/include/asm/global_data.h | 3 + arch/mips/include/asm/u-boot-mips.h | 2 + arch/mips/lib/bootm.c | 3 + arch/mips/lib/traps.c | 19 + arch/mips/mach-mtmips/Kconfig | 132 +++---- arch/mips/mach-mtmips/Makefile | 8 +- arch/mips/mach-mtmips/cpu.c | 58 +--- arch/mips/mach-mtmips/ddr_cal.c | 211 +++++++++++ arch/mips/mach-mtmips/ddr_calibrate.c | 309 ----------------- arch/mips/mach-mtmips/ddr_init.c | 194 +++++++++++ arch/mips/mach-mtmips/include/mach/ddr.h | 52 +++ arch/mips/mach-mtmips/include/mach/mc.h | 180 ++++++++++ arch/mips/mach-mtmips/include/mach/serial.h | 13 + arch/mips/mach-mtmips/lowlevel_init.S | 328 ------------------ arch/mips/mach-mtmips/mt7628/Makefile | 6 + arch/mips/mach-mtmips/mt7628/ddr.c | 173 +++++++++ arch/mips/mach-mtmips/mt7628/init.c | 109 ++++++ arch/mips/mach-mtmips/mt7628/lowlevel_init.S | 161 +++++++++ arch/mips/mach-mtmips/mt7628/mt7628.h | 104 ++++++ arch/mips/mach-mtmips/mt7628/serial.c | 34 ++ arch/mips/mach-mtmips/mt76xx.h | 32 -- arch/mips/mach-mtmips/spl.c | 44 +++ board/gardena/smart-gateway-mt7688/board.c | 2 + board/mediatek/mt7628/Kconfig | 12 + board/mediatek/mt7628/MAINTAINERS | 7 + board/mediatek/mt7628/Makefile | 3 + board/mediatek/mt7628/board.c | 8 + common/spl/spl_nor.c | 59 +++- ...gardena-smart-gateway-mt7688-ram_defconfig | 74 ---- .../gardena-smart-gateway-mt7688_defconfig | 16 +- configs/linkit-smart-7688-ram_defconfig | 65 ---- configs/linkit-smart-7688_defconfig | 16 +- configs/mt7628_rfb_defconfig | 46 +++ drivers/sysreset/Kconfig | 6 + drivers/sysreset/Makefile | 1 + drivers/sysreset/sysreset_resetctl.c | 48 +++ .../configs/gardena-smart-gateway-mt7688.h | 20 +- include/configs/linkit-smart-7688.h | 21 +- include/configs/mt7628.h | 55 +++ lib/Kconfig | 5 + lib/Makefile | 1 + tools/binman/README.entries | 15 + tools/binman/etype/u_boot_lzma_img.py | 28 ++ 51 files changed, 1952 insertions(+), 980 deletions(-) create mode 100644 arch/mips/dts/mediatek,mt7628-rfb.dts create mode 100644 arch/mips/dts/mt7628-u-boot.dtsi create mode 100644 arch/mips/mach-mtmips/ddr_cal.c delete mode 100644 arch/mips/mach-mtmips/ddr_calibrate.c create mode 100644 arch/mips/mach-mtmips/ddr_init.c create mode 100644 arch/mips/mach-mtmips/include/mach/ddr.h create mode 100644 arch/mips/mach-mtmips/include/mach/mc.h create mode 100644 arch/mips/mach-mtmips/include/mach/serial.h delete mode 100644 arch/mips/mach-mtmips/lowlevel_init.S create mode 100644 arch/mips/mach-mtmips/mt7628/Makefile create mode 100644 arch/mips/mach-mtmips/mt7628/ddr.c create mode 100644 arch/mips/mach-mtmips/mt7628/init.c create mode 100644 arch/mips/mach-mtmips/mt7628/lowlevel_init.S create mode 100644 arch/mips/mach-mtmips/mt7628/mt7628.h create mode 100644 arch/mips/mach-mtmips/mt7628/serial.c delete mode 100644 arch/mips/mach-mtmips/mt76xx.h create mode 100644 arch/mips/mach-mtmips/spl.c create mode 100644 board/mediatek/mt7628/Kconfig create mode 100644 board/mediatek/mt7628/MAINTAINERS create mode 100644 board/mediatek/mt7628/Makefile create mode 100644 board/mediatek/mt7628/board.c delete mode 100644 configs/gardena-smart-gateway-mt7688-ram_defconfig delete mode 100644 configs/linkit-smart-7688-ram_defconfig create mode 100644 configs/mt7628_rfb_defconfig create mode 100644 drivers/sysreset/sysreset_resetctl.c create mode 100644 include/configs/mt7628.h create mode 100644 tools/binman/etype/u_boot_lzma_img.py -- 2.17.1
