From mboxrd@z Thu Jan 1 00:00:00 1970 From: Wills Wang Date: Sun, 17 Jan 2016 02:13:46 +0800 Subject: [U-Boot] [PATCH v7 0/7] add support for atheros ath79 based SOCs Message-ID: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de These series of patch add support for atheros ath79 based SOCs in u-boot, at the present moment it's just available for ar933x and qca953x chip. This patch serises is based on mips_io_v4 branch on u-boot-mips repository [1] and tested on ar933x and qca953x board. [1] http://git.denx.de/?p=u-boot/u-boot-mips.git;a=shortlog;h=refs/heads/mips_io_v4 Changes in v7: - Use setbits_32 - Fix include path for SoC specific headers - Use CKSEGxADDR instead of KSEGxADDR for ar933x - Use CKSEGxADDR instead of KSEGxADDR for qca953x - remove map_physmem for debug port - Define spi_cs_activate/spi_cs_deactivate - Rename MHZ to ATH79_SPI_MHZ - Use clrsetbits_32 - Use KSEG1 address for debug port in ap121 - Use KSEG1 address for debug port in ap143 Changes in v6: - Move ar933x as separate patch - Add get_bootstrap in reset.c - Use map_physmem instead of KSEG1ADDR - Add arch_cpu_init for detect SOC type for early - Remove board.c - Define magic value in ddr.c - Remove wait loop in putc and getc - Use map_physmem instead of KSEG1ADDR - Add rrw_delay in ath79_spi_priv for more accurate timing - Remove ath79_spi_delay - Calculate delay in ath79_spi_set_speed - Convert SZ_XXX into hex in ap121.h - Remove useless CONFIG_SYS_INIT_SP_OFFSET in ap121.h - Add board_early_init_f for DDR and pin initialization - Select UART and SPI in ap121_defconfig Changes in v5: - Add independent Kconfig - Use SRAM for initial stack - Move DDR initialization into board_early_init_f - Convert DDR tap tunning code to C - Save SOC's version into arch_global_data - remove ar933x_serial_platdata - Import document "qca,ar9330-uart.txt" from kernel - Add support for debug UART - remove ar933x_spi_platdata - Import document "spi-ath79.txt" from kernel - Add delay for bitbang operation - Move CONFIG_SYS_TEXT_BASE into ap121.h, and remove config.mk - Remove useless README file - Remove useless checkboard function Changes in v4: - Use global_data to save CPU/DDR/AHB clock - Use arch_global_data to save SOC's type, revison and id - Auto calculate baudrate for serial driver - Move pinctrl code in serial driver into arch/mips/mach-ath79 - Use get_serial_clock to serial clock source - Use get_bus_freq instead of hardcode in SPI driver Changes in v3: - Move SoC specific header files into arch/mips/mach-ath79/include/mach - Optimize assembly code - Same code style convertion - Convert serial driver to driver model - Convert spi driver to driver model - Add support for device tree Changes in v2: - Move all SoC specific header files into arch/mips/include/asm/arch-ath79 - Check SOC type and extract common code into arch/mips/mach-ath79 - Move serial driver code into drivers/serial - Add a compatible spi driver - Add a reference board implemention Wills Wang (7): mips: add base support for QCA/Atheros ath79 SOCs mips: ath79: add support for AR933x SOCs mips: ath79: add support for QCA953x SOCs mips: ath79: add serial driver for ar933x SOC mips: ath79: add spi driver mips: ath79: add AP121 reference board mips: ath79: add AP143 reference board arch/mips/Kconfig | 6 + arch/mips/Makefile | 1 + arch/mips/dts/Makefile | 3 +- arch/mips/dts/ap121.dts | 43 + arch/mips/dts/ap143.dts | 43 + arch/mips/dts/ar933x.dtsi | 70 ++ arch/mips/dts/qca953x.dtsi | 72 ++ arch/mips/include/asm/global_data.h | 6 + arch/mips/mach-ath79/Kconfig | 46 + arch/mips/mach-ath79/Makefile | 10 + arch/mips/mach-ath79/ar933x/Makefile | 7 + arch/mips/mach-ath79/ar933x/clk.c | 89 ++ arch/mips/mach-ath79/ar933x/ddr.c | 316 ++++++ arch/mips/mach-ath79/ar933x/lowlevel_init.S | 279 +++++ arch/mips/mach-ath79/cpu.c | 203 ++++ arch/mips/mach-ath79/dram.c | 16 + arch/mips/mach-ath79/include/mach/ar71xx_regs.h | 1187 ++++++++++++++++++++ arch/mips/mach-ath79/include/mach/ath79.h | 143 +++ arch/mips/mach-ath79/include/mach/ddr.h | 13 + arch/mips/mach-ath79/include/mach/reset.h | 14 + arch/mips/mach-ath79/qca953x/Makefile | 7 + arch/mips/mach-ath79/qca953x/clk.c | 111 ++ arch/mips/mach-ath79/qca953x/ddr.c | 462 ++++++++ arch/mips/mach-ath79/qca953x/lowlevel_init.S | 185 +++ arch/mips/mach-ath79/reset.c | 71 ++ board/ath79/ap121/Kconfig | 9 + board/ath79/ap121/MAINTAINERS | 6 + board/ath79/ap121/Makefile | 5 + board/ath79/ap121/ap121.c | 47 + board/ath79/ap143/Kconfig | 9 + board/ath79/ap143/MAINTAINERS | 6 + board/ath79/ap143/Makefile | 5 + board/ath79/ap143/ap143.c | 63 ++ configs/ap121_defconfig | 42 + configs/ap143_defconfig | 43 + .../serial/qca,ar9330-uart.txt | 24 + doc/device-tree-bindings/spi/spi-ath79.txt | 19 + drivers/serial/Kconfig | 17 + drivers/serial/Makefile | 1 + drivers/serial/serial_ar933x.c | 254 +++++ drivers/spi/Kconfig | 8 + drivers/spi/Makefile | 1 + drivers/spi/ath79_spi.c | 237 ++++ include/configs/ap121.h | 87 ++ include/configs/ap143.h | 91 ++ 45 files changed, 4376 insertions(+), 1 deletion(-) create mode 100644 arch/mips/dts/ap121.dts create mode 100644 arch/mips/dts/ap143.dts create mode 100644 arch/mips/dts/ar933x.dtsi create mode 100644 arch/mips/dts/qca953x.dtsi create mode 100644 arch/mips/mach-ath79/Kconfig create mode 100644 arch/mips/mach-ath79/Makefile create mode 100644 arch/mips/mach-ath79/ar933x/Makefile create mode 100644 arch/mips/mach-ath79/ar933x/clk.c create mode 100644 arch/mips/mach-ath79/ar933x/ddr.c create mode 100644 arch/mips/mach-ath79/ar933x/lowlevel_init.S create mode 100644 arch/mips/mach-ath79/cpu.c create mode 100644 arch/mips/mach-ath79/dram.c create mode 100644 arch/mips/mach-ath79/include/mach/ar71xx_regs.h create mode 100644 arch/mips/mach-ath79/include/mach/ath79.h create mode 100644 arch/mips/mach-ath79/include/mach/ddr.h create mode 100644 arch/mips/mach-ath79/include/mach/reset.h create mode 100644 arch/mips/mach-ath79/qca953x/Makefile create mode 100644 arch/mips/mach-ath79/qca953x/clk.c create mode 100644 arch/mips/mach-ath79/qca953x/ddr.c create mode 100644 arch/mips/mach-ath79/qca953x/lowlevel_init.S create mode 100644 arch/mips/mach-ath79/reset.c create mode 100644 board/ath79/ap121/Kconfig create mode 100644 board/ath79/ap121/MAINTAINERS create mode 100644 board/ath79/ap121/Makefile create mode 100644 board/ath79/ap121/ap121.c create mode 100644 board/ath79/ap143/Kconfig create mode 100644 board/ath79/ap143/MAINTAINERS create mode 100644 board/ath79/ap143/Makefile create mode 100644 board/ath79/ap143/ap143.c create mode 100644 configs/ap121_defconfig create mode 100644 configs/ap143_defconfig create mode 100644 doc/device-tree-bindings/serial/qca,ar9330-uart.txt create mode 100644 doc/device-tree-bindings/spi/spi-ath79.txt create mode 100644 drivers/serial/serial_ar933x.c create mode 100644 drivers/spi/ath79_spi.c create mode 100644 include/configs/ap121.h create mode 100644 include/configs/ap143.h -- 1.9.1
