Re: [U-Boot] [PATCH v4 00/13] Initial Microchip PIC32MZ[DA] Support

2016-01-28 11:00 GMT+01:00 Purna Chandra Mandal purna.mandal@microchip.com:

This patch series adds support for Microchip PIC32MZ[DA] MIPS microcontroller platform. All drivers required to boot from MMC uSD card and network are included in it; clock, pinctrl, gpio, DDR2, serial, SDHCI, ethernet. This series been tested on PIC32MZ[DA] Starter Kit.

This series is generated on u-boot/master branch. A tree with these changes is available at [1].

applied to u-boot-mips, thanks

Changes in v4:

• update kconfig dependency and default selection

• move CMD_MEMTEST, CMD_MEMINFO to defconfig
• increase SYS_MALLOC_F_LEN to 0x600
• use auto-generated defconfig - no hand edit
• remove ofdata_to_platdata, and replace platdata with priv
• replace pic32_ioremap() with ioremap()
• use distro boot commands from config_distro_bootcmd.h
• separate old booting logic as legacy_bootcmd
• merge wrappers with eth operation callbacks
• read phy address from device-tree
• rename functions (e.g. _eth_xyz() with pic32_eth_xyz())

Changes in v2:

• move PIC32 specific headers to arch/mips/mach-pic32/include/mach/
• define register-base as physical address
• drop CONFIG_PIC32_SUPPORTS_FDT_BOOT
• add mpll get clock rate
• add pinconf routine for configuring pin property
• fix missing/corrupted chars during baud rate change
• remove loop until any char is avaialbale in getc()
• move ddr2 initialization from board/microchip/ to drivers/ddr/microchip
• drop board_early_init_f
• use macro LEAF(), END() for lowlevel_init
• move initialization of board_init_f() argument to common start.S
• move initdram() from board/microchip/ to mach-pic32/cpu.c
• remove MIPS virtual address in favor physical one in dts file
• move CONFIG_SYS_TEXT_BASE (from board/*/config.mk) to include/configs/<board>.h
• drop sdhci shared bus configuration (for shared interrupt, clock pins)
• drop shared bus (shared pin selection) configuration.
• replace unbounded loop with wait_for_bit()
• replace register access as readl/writel(base + offset)
• translate (dts provided) physical address to MIPS kseg1 address before use
