--- Changelog for v4: - rebase to [247aa5a191159ea7e03bf1918e22fbbb784cd410] - fix rebase issues - use spl without SPL_DM - fix some more codingstyle - fix some more typo - add comments about writing sdram controler - keep .noreoder and do not use delay slot
Changelog for v3: - change cpu clock id from CLK_CPU to CLK_CPU_THROT - migrate all APB dev's clock id to CLK_APB - remove uarts' <reg-shift> property to use default value <0> - move /clocks/acc node to /soc/acc - call clk_request() before use a clk - make get_tbclk() return 1/2 clock of cpu - disable debug_uart by default - add ops for cpu_throt_factor clk - declare MSEC_PER_SEC for converting between sec and msec - return a error code when the wdt clock is out of range - minor format and codingstyle fixes - rebase to [9859465bfe838bc8264d45e1a1bed847bba74bad]
Changelog for v2: 1. dtsi: add status disabled for uart0 ~ uart11 remove bootargs from chosen make serial0 alias for uart2 oscillator remove @0 unit-address change uart2 address to kuseg
2. cleanup Kconfig and update defconfig - make these options configurable, disabled by default: CMD_DM DM_ETH DM_GPIO DM_SPI DM_SPI_FLASH DM_RESET PINCONF PINCTRL PINMUX RESET_LSMIPS - make these options configurable, enabled by default: CLK DISPLAY_CPUINFO SYSRESET ROM_EXCEPTION_VECTORS - disabled: CONFIG_ENV_IS_IN_SPI_FLASH
3. fix codingstyle drivers/watchdog/lsmips-wdt.c - priv->base + offset - add comment for default clock value
4. remove address base definition header - remove arch/mips/mach-lsmips/ls1c300/ls1c300.h - clean up files uses this header
5. spl and debug uart - add comment for spl & debug uart pinmuxing - cleanup unused registers base header
6. dtsi - add "loongson,ls1c300-uart" to all uart node
7. board dts - add memory node to board dts, start at 0x80000000, size 64MB
8. Kconfig - make ROM_EXCEPTION_VECTORS user configureable - enable ROM_EXCEPTION_VECTORS in defconfig
9. - seperate sdram_init to sdram_init.S - add macro helpers to do sdram, pll lowlevel init
10. dtsi - move clock nodes to /clocks/xxx
11. - define CONFIG_SKIP_LOWLEVEL_INIT to 1
12. - remove option PINCTRL_LS1C300 from Kconfig
13. - dram_init, use get_ram_size() to detect ram size.
14. clk driver - create custom clock ops for PLL - remove debug code
15. - rebase to 59bffec43a657598b194b9eb30dc01eec06078c7 - remove CONFIG_SYS_MONITOR_BASE from include/configs/
