The Linux coding style guide (Documentation/process/coding-style.rst) clearly says: It's a **mistake** to use typedef for structures and pointers. Besides, using typedef for structures is annoying when you try to make headers self-contained. Let's say you have the following function declaration in a header: void foo(bd_t *bd); This is not self-contained since bd_t is not defined. To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h> #include <asm/u-boot.h> void foo(bd_t *bd); Then, the include direcective pulls in more bloat needlessly. If you use 'struct bd_info' instead, it is enough to put a forward declaration as follows: struct bd_info; void foo(struct bd_info *bd); Right, typedef'ing bd_t is a mistake. I used coccinelle to generate this commit. The semantic patch that makes this change is as follows: <smpl> @@ typedef bd_t; @@ -bd_t +struct bd_info </smpl> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> |

Overview
=========
The P1010RDB-PB is a Freescale Reference Design Board that hosts the P1010 SoC.
P1010RDB-PB is a variation of previous P1010RDB-PA board.
The P1010 is a cost-effective, low-power, highly integrated host processor
based on a Power Architecture e500v2 core (maximum core frequency 1GHz),that
addresses the requirements of several routing, gateways, storage, consumer,
and industrial applications. Applications of interest include the main CPUs and
I/O processors in network attached storage (NAS), the voice over IP (VoIP)
router/gateway, and wireless LAN (WLAN) and industrial controllers.
The P1010RDB-PB board features are as following:
Memory subsystem:
- 1G bytes unbuffered DDR3 SDRAM discrete devices (32-bit bus)
- 32M bytes NOR flash single-chip memory
- 2G bytes NAND flash memory
- 16M bytes SPI memory
- 256K bit M24256 I2C EEPROM
- I2C Board EEPROM 128x8 bit memory
- SD/MMC connector to interface with the SD memory card
Interfaces:
- Three 10/100/1000 BaseT Ethernet ports (One RGMII and two SGMII)
- PCIe 2.0: two x1 mini-PCIe slots
- SATA 2.0: two SATA interfaces
- USB 2.0: one USB interface
- FlexCAN: two FlexCAN interfaces (revision 2.0B)
- UART: one USB-to-Serial interface
- TDM: 2 FXS ports connected via an external SLIC to the TDM interface.
1 FXO port connected via a relay to FXS for switchover to POTS
Board connectors:
- Mini-ITX power supply connector
- JTAG/COP for debugging
POR: support critical POR setting changed via switch on board
PCB: 6-layer routing (4-layer signals, 2-layer power and ground)

SW3[1:8]= 10010000
SW4[1:4]= 1010

P1010RDB-PB boot mode settings via DIP-switch
=============================================
SW4[1:4]= 1111 and SW3[3:4]= 00 for 16bit NOR boot
SW4[1:4]= 1010 and SW3[3:4]= 01 for 8bit NAND boot
SW4[1:4]= 0110 and SW3[3:4]= 00 for SPI boot
SW4[1:4]= 0111 and SW3[3:4]= 10 for SD boot
Note: 1 stands for 'on', 0 stands for 'off'
Switch P1010RDB-PB boot mode via software without setting DIP-switch
====================================================================
=> run boot_bank0 (boot from NOR bank0)
=> run boot_bank1 (boot from NOR bank1)
=> run boot_nand (boot from NAND flash)
=> run boot_spi (boot from SPI flash)
=> run boot_sd (boot from SD card)
Frequency combination support on P1010RDB-PB
=============================================
SW1[4:7] SW5[1] SW5[5:8] SW2[2] Core(MHz) Platform(MHz) DDR(MT/s)
0101 1 1010 0 800 400 800
1001 1 1010 0 800 400 667
1010 1 1100 0 667 333 667
1000 0 1010 0 533 266 667

Setting of pin mux
==================
Since pins multiplexing, TDM and CAN are muxed with SPI flash.
SDHC is muxed with IFC. IFC and SPI flash are enabled by default.
To enable TDM:
=> setenv hwconfig fsl_p1010mux:tdm_can=tdm
=> save;reset
To enable FlexCAN:
=> setenv hwconfig fsl_p1010mux:tdm_can=can
=> save;reset
To enable SDHC in case of NOR/NAND/SPI boot
a) For temporary use case in runtime without reboot system
run 'mux sdhc' in U-Boot to validate SDHC with invalidating IFC.
b) For long-term use case
set 'esdhc' in hwconfig and save it.
To enable IFC in case of SD boot
a) For temporary use case in runtime without reboot system
run 'mux ifc' in U-Boot to validate IFC with invalidating SDHC.
b) For long-term use case
set 'ifc' in hwconfig and save it.
Build images for different boot mode
====================================
First setup cross compile environment on build host
$ export CROSS_COMPILE=<your-compiler-path>/powerpc-linux-gnu-
1. For NOR boot
$ make P1010RDB-PB_NOR
2. For NAND boot
$ make P1010RDB-PB_NAND
3. For SPI boot
$ make P1010RDB-PB_SPIFLASH
4. For SD boot
$ make P1010RDB-PB_SDCARD
