[U-Boot] [PATCH v3 09/14] board: Add Microchip PIC32MZ[DA]-Starter-Kit board.

Purna Chandra Mandal
2016-01-12T10:18:24Z

This adds support for Microchip PIC32MZ[DA] StarterKit board
based on a PIC32MZ[DA] family of microcontroller.

Signed-off-by: Purna Chandra Mandal <purna.mandal@microchip.com>

---

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.
+
+Visit http://microchip.com for details.
