2015-07-31powerpc/mpc85xx: SECURE BOOT- NAND secure boot target for P3041Aneesh Bansal
Secure Boot Target is added for NAND for P3041. For mpc85xx SoCs, the core begins execution from address 0xFFFFFFFC. In case of secure boot, this default address maps to Boot ROM. The Boot ROM code requires that the bootloader(U-boot) must lie in 0 to 3.5G address space i.e. 0x0 - 0xDFFFFFFF. In case of NAND Secure Boot, CONFIG_SYS_RAMBOOT is enabled and CPC is configured as SRAM. U-Boot binary will be located on SRAM configured at address 0xBFF00000. In the U-Boot code, TLB entries are created to map the virtual address 0xFFF00000 to physical address 0xBFF00000 of CPC configured as SRAM.

2014-11-21fdt: Allow ft_board_setup() to report failureSimon Glass
This function can fail if the device tree runs out of space. Rather than silently booting with an incomplete device tree, allow the failure to be detected. Unfortunately this involves changing a lot of places in the code. I have not changed behvaiour to return an error where one is not currently returned, to avoid unexpected breakage. Eventually it would be nice to allow boards to register functions to be called to update the device tree. This would avoid all the many functions to do this. However it's not clear yet if this should be done using driver model or with a linker list. This work is left for later.

This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.

Fix PHY addresses for QSGMII Riser Card working in SGMII mode on board P3041/P5020/P4080/P5040/B4860. QSGMII Riser Card can work in SGMII mode, but having the different PHY addresses. So the following steps should be done: 1. Confirm whether QSGMII Riser Card is used. 2. If yes, set the proper PHY address. Generally, the function is_qsgmii_riser_card() is for step 1, and set_sgmii_phy() for step 2. However, there are still some special situations, take P5040 and B4860 as examples, the PHY addresses need to be changed when serdes protocol is changed, so it is necessary to confirm the protocol before setting PHY addresses.

Most 85xx boards can be built as a 32-bit or a 36-bit. Current code sometimes displays which of these is actually built, but it's inconsistent. This is especially problematic since the "default" build for a given 85xx board can be either one, so if you don't see a message, you can't always know which size is being used. Not only that, but each board includes code that displays the message, so there is duplication.

Add support for RGMII, SGMII, and XAUI (10Gb) Ethernet on P3041DS & P5020DS ("Hydra"). The lane_to_slot[] array is initialized dynamically, since board switches can be used to control the muxing of SERDES lanes to slots. The BRDCFG1 PIXIS register is used to route the MII bus to the appropriate slot. The SERDES configuration is queried to help determine the routing between MACs and slot/phy combination. If a XAUI card is inserted, muxing for that card is enabled and never turned off. The PHY address for the 10G XAUI card depends on the slot in which it's inserted. If it's in slot 1, the address is 4. If it's in slot 2, the address is 0. Update the MDIO routing in the P3041DS and P5020DS device trees based on the board-level muxing. The SERDES configuration determines which SGMII/XGMII boards are located in which slots, and so the MDIO bus needs to be muxed correctly whenever talking to a PHY connected to any Fman MAC. The Fman Ethernet nodes in the device tree also need to be routed to the correct PHYs. Removed CONFIG_SYS_FMAN_FW as its not used anywhere.

Add support for RGMII, SGMII, and XAUI (10Gb) Ethernet on P4080DS. The board supports add-on cards for SGMII and XAUI functionality. Which slots on the board these cards are in is a function of the SERDES option selected and muxes on the board. Additionally because of the high-configurablity which MDIO bus one is connected to is "selected" via an FPGA register. We create dummy MDIO bus for the phy layer and hide the mux manipulation in this dummy layer. Add fman fdt helper function in board common code it'll be used by several freescale boards that do various muxing of the MDIO signals based on which controller/interface one is trying to talk to.
