* malta: support for coreFPGA6 boardsPaul Burton2013-11-09-0/+126
| | | | | | | | | | | | | | | | | | | | | This patch adds support for running on Malta boards using coreFPGA6 core cards, including support for the msc01 system controller used with them. The system controller is detected at runtime allowing one U-boot binary to run on a Malta with either. Due to the PCI I/O base differing between Maltas using gt64120 & msc01 system controllers, the UART setup is modified slightly. A second UART is added so that there is one pointing at the correct address for each system controller. The Malta board then defines its own default_serial_console function to select the correct one at runtime. The incorrect UART will simply not function. Tested on: - A coreFPGA6 Malta running interAptiv and proAptiv bitstreams, both with and without an L2 cache. - QEMU. Signed-off-by: Paul Burton <paul.burton@imgtec.com>

| | | | | | | | | | | | | | | | | | | configuration space. Previously, the address of a requested capability is define like that "#define PCI_DCR 0x78" But, the addresses of capabilities is different with regard to PCIe revs. So this method is not flexible. Now a function to get the address of a requested capability is added and used. It can get the address dynamically by capability ID. The step of this function: 1. Read Status register in PCIe configuration space to confirm that Capabilities List is valid. 2. Find the address of Capabilities Pointer Register. 3. Find the address of requested capability from the first capability. Signed-off-by: Zhao Qiang <B45475@freescale.com>

* powerpc/pcie: add PCIe version 3.x supportZang Roy-R619112013-08-09-6/+14
| | | | | | | | | | | | | | | | | | | | | | | | | T4240 PCIe IP is version 3.0 and has some update comparing previous QorIQ products. 1. Move Freescale specific register define to arch/powerpc/include/asm/fsl_pci.h and update the register offset define for T4240. 2. add the status/control register define use status/control register to judge the link status 3. The original code uses 'Programming Interface' field to judge if PCIE is EP or RC mode, however, T4240 does not support this functionality. According to PCIE specification, 'Header Type' offset 0x0e is used to indicate header type, so for PCIE controller, the patch changes code to use 'Header Type' field to identify if the PCIE is RC or EP mode.

* powerpc/boot: Change the macro of Boot from SRIO and PCIE master moduleLiu Gang2013-06-20-3/+3
| | | | | | | | | | | | | | | | | Currently, the macro "CONFIG_SYS_FSL_SRIO_PCIE_BOOT_MASTER" can enable the master module of Boot from SRIO and PCIE on a platform. But this is not a silicon feature, it's just a specific booting mode based on the SRIO and PCIE interfaces. So it's inappropriate to put the macro into the file arch/powerpc/include/asm/config_mpc85xx.h. Change the macro "CONFIG_SYS_FSL_SRIO_PCIE_BOOT_MASTER" to "CONFIG_SRIO_PCIE_BOOT_MASTER", remove them from arch/powerpc/include/asm/config_mpc85xx.h file, and add those macros in configuration header file of each board which can support the master module of Boot from SRIO and PCIE.

| | | | | | | | | | | | Due to SerDes configuration error, if we set the PCI-e controller link width as x8 in RCW and add a narrower width(such as x4, x2 or x1) PCI-e device to PCI-e slot, it fails to train down to the PCI-e device's link width. According to p4080ds errata PCIe-A003, we reset the PCI-e controller link width to x4 in u-boot. Then it can train down to x2 or x1 width to make the PCI-e link between RC and EP.

| | | | | | | | | | | | | | | | | Currently, the SRIO and PCIE boot master module will be compiled into the u-boot image if the macro "CONFIG_FSL_CORENET" has been defined. And this macro has been included by all the corenet architecture platform boards. But in fact, it's uncertain whether all corenet platform boards support this feature. So it may be better to get rid of the macro "CONFIG_FSL_CORENET", and add a special macro for every board which can support the feature. This special macro will be defined in the header file "arch/powerpc/include/asm/config_mpc85xx.h". It will decide if the SRIO and PCIE boot master module should be compiled into the board u-boot image.

The processor booting from PCIE can do without flash for u-boot image. The image can be fetched from another processor's memory space by PCIE link connected between them. The processor booting from PCIE is slave, the processor booting from normal flash memory space is master, and it can help slave to boot from master's memory space. When boot from PCIE, slave's core should be in holdoff after powered on for some specific requirements. Master will release the slave's core at the right time by PCIE interface. Environment and requirement: master: 1. NOR flash for its own u-boot image, ucode and ENV space. 2. Slave's u-boot image is in master NOR flash. 3. Normally boot from local NOR flash. 4. Configure PCIE system if needed. slave: 1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV. 2. Boot location should be set to one PCIE interface by RCW. 3. RCW should configure the SerDes, PCIE interfaces correctly. 4. Must set all the cores in holdoff by RCW. 5. Must be powered on before master's boot. For the master module, need to finish these processes: 1. Initialize the PCIE port and address space. 2. Set inbound PCIE windows covered slave's u-boot image stored in master's NOR flash. 3. Set outbound windows in order to configure slave's registers for the core's releasing. 4. Should set the environment variable "bootmaster" to "PCIE1", "PCIE2" or "PCIE3" using the following command: setenv bootmaster PCIE1 saveenv Signed-off-by: Liu Gang <Gang.Liu@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>

* pci: move pcidelay code to new location just before PCI bus scanAnatolij Gustschin2011-10-15-13/+17
| | | | | | | | | | | | | | | | | | | | PCI cards might need some time after reset to respond. On some boards (mpc5200 or mpc8260 based) the PCI bus reset is deasserted at pci_init_board() time, so we currently can not use available "pcidelay" option for waiting before PCI bus scan since this waiting takes place before calling pci_init_board(). By moving the pcidelay code to the new location using of the "pcidelay" option is possible on mpc5200 or mpc8260 based boards, too. Since pci_hose_scan() could be called multiple times, restrict the function to wait only during its first call and to ignore pcidelay for any further call (as pointed out by Matthias).

* fsl_pci: Update PCIe boot ouputPeter Tyser2011-01-14-18/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change does the following: - Adds printing of negotiated link width. This information can be useful when debugging PCIe issues. - Makes it optional for boards to implement board_serdes_name(). Previously boards that did not implement it would print unsightly output such as "PCIE1: Connected to <NULL>..." - Rewords the PCIe boot output to reduce line length and to make it clear that the "base address XYZ" value refers to the base address of the internal processor PCIe registers and not a standard PCI BAR value. - Changes "PCIE" output to the standard "PCIe" Before change: PCIE1: connected to <NULL> as Root Complex (base addr ef008000) 01:00.0 - 10b5:8518 - Bridge device 02:01.0 - 10b5:8518 - Bridge device 02:02.0 - 10b5:8518 - Bridge device 02:03.0 - 10b5:8518 - Bridge device PCIE1: Bus 00 - 05 PCIE2: connected to <NULL> as Endpoint (base addr ef009000) PCIE2: Bus 06 - 06 After change: PCIe1: Root Complex of PEX8518 Switch, x4, regs @ 0xef008000 01:00.0 - 10b5:8518 - Bridge device 02:01.0 - 10b5:8518 - Bridge device 02:02.0 - 10b5:8518 - Bridge device 02:03.0 - 10b5:8518 - Bridge device PCIe1: Bus 00 - 05 PCIe2: Endpoint of VPX Fabric A, x2, regs @ 0xef009000 PCIe2: Bus 06 - 06 Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* powerpc/fsl-pci: Add generic code to setup PCIe controllersKumar Gala2011-01-14-0/+148
| | | | | | | | | | | | | | | | | | Since all the PCIe controllers are connected over SERDES on the SoCs we can utilize is_serdes_configured() to determine if a controller is enabled. After which we can setup the ATMUs and LAWs for the controller in a common fashion and allow board code to specify what the controller is connected to for reporting reasons. We also provide a per controller (rather than all) for some systems that may have special requirements. Finally, we refactor the code used by the P1022DS to utilize the new generic code.

* powerpc/fsl-pci: Determine pci_controller based on cfg addr for dts fixupKumar Gala2011-01-14-1/+16
| | | | | | | | | | | | | | Previously we passed in a specifically named struct pci_controller to determine if we had setup the particular PCI bus. Now we can search for the struct so we dont have to depend on the name or the struct being statically allocated. Introduced new find_hose_by_cfg_addr() to get back a pci_controller struct back by searching for it means we can do things like dynamically allocate them or not have to expose the static structures to all users.

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
* pci: Use intelligent indentation for CONFIG_PCI_SCAN_SHOWPeter Tyser2010-11-14-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When CONFIG_PCI_SCAN_SHOW is defined U-Boot prints out PCI devices as they are found during bootup, eg: PCIE1: connected as Root Complex 01:00.0 - 10b5:8518 - Bridge device 02:01.0 - 10b5:8518 - Bridge device 03:00.0 - 10b5:8112 - Bridge device 04:01.0 - 8086:1010 - Network controller 04:01.1 - 8086:1010 - Network controller 02:02.0 - 10b5:8518 - Bridge device 02:03.0 - 10b5:8518 - Bridge device 06:00.0 - 10b5:8518 - Bridge device 07:00.0 - 10b5:8518 - Bridge device 08:00.0 - 1957:0040 - Processor 07:01.0 - 10b5:8518 - Bridge device 09:00.0 - 10b5:8112 - Bridge device 07:02.0 - 10b5:8518 - Bridge device PCIE1: Bus 00 - 0b PCIE2: connected as Root Complex 0d:00.0 - 1957:0040 - Processor PCIE2: Bus 0c - 0d This information is useful, but its difficult to determine the PCI bus topology. To things clearer, we can use indention to make it more obvious how the PCI bus is organized. For the example above, the updated output with this change is: PCIE1: connected as Root Complex 01:00.0 - 10b5:8518 - Bridge device 02:01.0 - 10b5:8518 - Bridge device 03:00.0 - 10b5:8112 - Bridge device 04:01.0 - 8086:1010 - Network controller 04:01.1 - 8086:1010 - Network controller 02:02.0 - 10b5:8518 - Bridge device 02:03.0 - 10b5:8518 - Bridge device 06:00.0 - 10b5:8518 - Bridge device 07:00.0 - 10b5:8518 - Bridge device 08:00.0 - 1957:0040 - Processor 07:01.0 - 10b5:8518 - Bridge device 09:00.0 - 10b5:8112 - Bridge device 07:02.0 - 10b5:8518 - Bridge device PCIE1: Bus 00 - 0b PCIE2: connected as Root Complex 0d:00.0 - 1957:0040 - Processor PCIE2: Bus 0c - 0d In the examples above, an MPC8640 is connected to a PEX8518 PCIe switch (01:00 and 02:0x), which is connected to another PEX8518 PCIe switch (06:00 and 07:0x), which then connects to a MPC8572 processor (08:00). Also, the MPC8640's PEX8518 PCIe switch is connected to a PCI ethernet card (04:01) via a PEX8112 PCIe-to-PCI bridge (03:00). Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
