* fdt: Allow ft_board_setup() to report failureSimon Glass2014-11-21-1/+3
| | | | | | | | | | | | | | | | | | 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.

* net: Merge asm/fsl_enet.h into fsl_mdio.hClaudiu Manoil2014-09-08-1/+0
| | | | | | | | | | | | | | | fsl_enet.h defines the mapping of the usual MII management registers, which are included in the MDIO register block common to Freescale ethernet controllers. So it shouldn't depend on the CPU architecture but it should be actually part of the arch independent fsl_mdio.h. To remove the arch dependency, merge the content of asm/fsl_enet.h into fsl_mdio.h. Some files (like fm_eth.h) were simply including fsl_enet.h only for phy.h. These were updated to include phy.h instead. Signed-off-by: Claudiu Manoil <claudiu.manoil@freescale.com>

* fsl: Change fsl_phy_enet_if to phy_interface_tAndy Fleming2011-04-20-1/+2
| | | | | | | | | | | | The fsl_phy_enet_if enum was, essentially, the phy_interface_t enum. This meant that drivers which used fsl_phy_enet_if to deal with PHY interfaces would have to convert between the two (or we would have to have them mirror each other, and deal with the ensuing maintenance headache). Instead, we switch all clients of fsl_phy_enet_if over to phy_interface_t, which should become the standard, anyway.

* tsec: Convert tsec to use PHY LibAndy Fleming2011-04-20-0/+7
| | | | | | | | | | | | | This converts tsec to use the new PHY Lib. All of the old PHY support is ripped out. The old MDIO driver is split off, and placed in fsl_mdio.c. The initialization is modified to initialize the MDIO driver as well. The powerpc config file is modified to configure PHYLIB if TSEC_ENET is configured.

| | | | | | | | | | | fdt_fixup_esdhc() will either disable or enable eSDHC nodes, and also will fixup clock-frequency property. Plus, since DR USB and eSDHC are mutually exclusive, we should only configure the eSDHC if asked through hwconfig.

* mpc83xx: Add PCI-E support for MPC837XEMDS boardsAnton Vorontsov2009-01-21-4/+2
| | | | | | | | | | | MPC837XEMDS boards can support PCI-E via "PCI-E riser card". The card provides two PCI-E (x2) ports. Though, only one port can be used in x2 mode. Two ports can function simultaneously in x1 mode. PCI-E x1/x2 modes can be switched via "pex_x2" environment variable.

* mpc83xx: fix PCI scan hang on the standalone MPC837xE-MDS boardsAnton Vorontsov2008-10-21-0/+41
| | | | | | | | | | | | | | | | | | | | | | | The MPC837xE-MDS board's CPLD can auto-detect if the board is on the PIB, standalone or acting as a PCI agent. User's Guide says: - When the CPLD recognizes its location on the PIB it automatically configures RCW to the PCI Host. - If the CPLD fails to recognize its location then it is automatically configured as an Agent and the PCI is configured to an external arbiter. This sounds good. Though in the standalone setup the CPLD sets PCI_HOST flag (it's ok, we can't act as PCI agents since we receive CLKIN, not PCICLK), but the CPLD doesn't set the ARBITER_ENABLE flag, and without any arbiter bad things will happen (here the board hangs during any config space reads). In this situation we must disable the PCI. And in case of anybody really want to use an external arbiter, we provide "pci_external_aribter" environment variable.

* mpc83xx: fix serdes setup for the MPC8378E boardsAnton Vorontsov2008-10-21-1/+1
| | | | | | | | | | | | | | | | | | | | | | MPC837xE specs says that SerDes1 has: — Two lanes running x1 SGMII at 1.25 Gbps; — Two lanes running x1 SATA at 1.5 or 3.0 Gbps. And for SerDes2: — Two lanes running x1 PCI Express at 2.5 Gbps; — One lane running x2 PCI Express at 2.5 Gbps; — Two lanes running x1 SATA at 1.5 or 3.0 Gbps. The spec also explicitly states that PEX options are not valid for the SD1. Nevertheless MPC8378 RDB and MDS boards configure the SD1 for PEX, which is wrong to do.

* Change initdram() return type to phys_size_tBecky Bruce2008-06-12-1/+1
| | | | | | | | | | | | | | | | | | | This patch changes the return type of initdram() from long int to phys_size_t. This is required for a couple of reasons: long int limits the amount of dram to 2GB, and u-boot in general is moving over to phys_size_t to represent the size of physical memory. phys_size_t is defined as an unsigned long on almost all current platforms. This patch *only* changes the return type of the initdram function (in include/common.h, as well as in each board's implementation of initdram). It does not actually modify the code inside the function on any of the platforms; platforms which wish to support more than 2GB of DRAM will need to modify their initdram() function code. Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc MPC8641HPCN. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
