[U-Boot] [PATCH] powerpc/85xx: Add basic support for P1023RDS board

Roy Zang tie-fei.zang at freescale.com
Wed Jun 8 06:51:27 CEST 2011


The P1023RDS board is the reference board for the P1023 SoC.

Add support for booting it from NOR or NAND, with fixed 2G of DDR, PCIe,
UART, I2C, etc.

+Overview
+--------
+The P1023 process includes a performance optimized implementation of the
+QorIQ data Path Acceleration Architecture (DPAA).  This architecture
+provides the infrastructure to support simplified sharing of networking
+interfaces and accelerators by multiple CPU cores. P1023 is an e500 based
+dual core SOC.
+
+P1023RDS board is a Low End Dual core platform supporting the P1023
+processor of QorIQ series.
+
+Building U-boot
+---------------
+To build the u-boot for P1023RDS:
+Configure to NOR boot:
+	make P1023RDS_config
+Configure to NAND boot:
+	make P1023RDS_NAND_config
+Build:
+	make
+
+Board Switches
+--------------
+Most switches on the board should not be changed.  The most frequent
+user-settable switches on the board are used to configure
+the flash banks.
+
+J4: all open
+
+Default NOR flash boot switch setting:
+ Sw3[1:8]: off on on off on on off off
+ Sw4[1:8]: off off off on off off off off
+ Sw6[1:8]: off on off on off on on off
+ Sw7[1:8]: off on off off on off off off
+ Sw8[1:8]: on off off off off off off off
+
+For NAND flash boot,set
+Sw4[1:4]: off on on on
+
+The default native ethernet setting is for RGMII mode.
+To use SGMII mode, set
+SW8[1:2]: OFF OFF
+SW7[6:7]: ON ON
+
+Memory Map
+----------
+0x0000_0000	0x7fff_ffff	DDR			2G Cacheable
+0x8000_0000	0xbfff_ffff	PCI Express Mem		1G non-cacheable
+0xc000_0000	0xdfff_ffff	PCI			512M non-cacheable
+0xe100_0000	0xe3ff_ffff	PCI IO range		4M non-cacheable
+
+0xe000_0000	0xe003_ffff	BCSR			256K BCSR
+0xee00_0000	0xefff_ffff	NOR flash		32M NOR flash
+0xff00_0000	0xff3f_ffff	DPAA_QBMAN		4M
+0xff60_0000	0xff7f_ffff	CCSR			2M non-cacheable
+0xffa0_0000	0xffaf_ffff	NAND FLASH		1M non-cacheable
+0xffd0_0000	0xffd0_3fff	L1 for stack		16K Cacheable TLB0
+
+Flashing u-boot Images
+---------------
+To program the image in the boot flash bank:
+NOR flash boot:
+	=> tftp 1000000 u-boot.bin
+	=> protect off all
+	=> erase eff80000 efffffff
+	=> cp.b 1000000 eff80000 80000
+
+NAND flash boot:
+	=> tftp 1000000 u-boot-nand.bin
+	=> nand erase 0 80000
+	=> nand write 1000000 0 80000
+
+Firmware ucode location
+---------------------------------
+Microcode(ucode) to FMAN's IRAM is needed to make FMAN Ethernet work.
+u-boot loads ucode FLASH. The location for ucode:
+NOR Flash: 0xfe000000
+NAND Flash: 0x1f00000
+
+Using the Device Tree Source File
+---------------------------------
+To create the DTB (Device Tree Binary) image file,
+use a command similar to this:
+
+	dtc -b 0 -f -I dts -O dtb p1023rds.dts > p1023rds.dtb
+
+Likely, that .dts file will come from here;
+
+	linux-2.6/arch/powerpc/boot/dts/p1023rds.dts
+or
+	make p1023rds.dtb ARCH=powerpc
+in linux-2.6 directory.
+
+Booting Linux
+-------------
+Place a linux uImage in the TFTP disk area.
+
+	tftp 1000000 uImage
+	tftp 2000000 rootfs.ext2.gz.uboot
+	tftp c00000 p1023rds.dtb
+	bootm 1000000 2000000 c00000
