Changes in v4:
- create defconfig by 'make savedefconfig'
- drop explicit SYS_BAUDRATE_TABLE in favor of default one
Changes in v3:
- drop SKIP_LOWLEVEL_INIT, GBL_DATA_OFFSET from config header
- move CMD_MEMTEST, CMD_MEMINFO to defconfig
- increase SYS_MALLOC_F_LEN to 0x600
- use auto-generated defconfig - no hand edit
Changes in v2:
- move CONFIG_SYS_TEXT_BASE (from board/*/config.mk) to include/configs/<board>.h

+PIC32MZ[DA] Starter Kit +---------------------------------------- +PIC32MZ[DA] Starter Kit is based on PIC32MZ[DA] family of micro-controller. +This family is powered by MIPS M14KEC 32bit general purpose core and has +advanced microcontroller features and peripherals.
+This processor boots with proprietary stage1 bootloader running from internal +boot-flash. Stage1 bootloader inturns locates and jumps to U-Boot programmed +on internal program-flash. Finally U-Boot loads OS image (along with other +required files for booting) from either uSD card, or ethernet, or from USB +storage.
+To boot Linux following three files are mandatory - uEnv.txt (custom U-Boot +environment file), uImage, *.dtb (platform device-tree-blob file).
+U-Boot jumps to Linux using UHI specification.
