* pci: Add general support for execution of video ROMsSimon Glass2014-11-25-1/+279
| | | | | | | | | | | | | | | | | | Some platforms don't have native code for dealing with their video hardware. In some cases they use a binary blob to set it up and perform required actions like setting the video mode. This approach is a hangover from the old PC days where a ROM was provided and executed during startup. Even now, these ROMs are supplied as a way to set up video. It avoids the code for every video chip needing to be provided in the boot loader. But it makes the video much less flexible - e.g. it is not possible to do anything else while the video init is happening (including waiting hundreds of milliseconds for display panels to start up). In any case, to deal with this sad state of affairs, provide an API for execution of x86 video ROMs, either natively or through emulation. Signed-off-by: Simon Glass <sjg@chromium.org>

* pci: Honour pci_skip_dev()Thierry Reding2014-11-23-0/+3
| | | | | | | | | | | | | | When enumerating devices, honour the pci_skip_dev() function. This can be used by PCI controller drivers to restrict which devices will be probed. This is required by the NVIDIA Tegra PCIe controller driver, which will fail with a data abort exception if an access is attempted to a device number larger than 0 outside of bus 0. pci_skip_dev() is therefore implemented to prevent any such accesses.

* linux/kernel.h: sync min, max, min3, max3 macros with LinuxMasahiro Yamada2014-11-23-3/+5
| | | | | | | | | | | | | | | | | | | | U-Boot has never cared about the type when we get max/min of two values, but Linux Kernel does. This commit gets min, max, min3, max3 macros synced with the kernel introducing type checks. Many of references of those macros must be fixed to suppress warnings. We have two options: - Use min, max, min3, max3 only when the arguments have the same type (or add casts to the arguments) - Use min_t/max_t instead with the appropriate type for the first argument Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Pavel Machek <pavel@denx.de> Acked-by: Lukasz Majewski <l.majewski@samsung.com> Tested-by: Lukasz Majewski <l.majewski@samsung.com> [trini: Fixup arch/blackfin/lib/string.c] Signed-off-by: Tom Rini <trini@ti.com>

* 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>

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.

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.

* | pci: clean up some whitespace and formattingAndrew Sharp2012-09-02-70/+91
| | | | | | | | | | | | | | | | | | | | | | I tried to clean up the white space and formatting offenses and inconsistencies in the generic PCI code that obviously has been around for some time. Emphasis on large increases in readability and maintainability and consistency. I omitted the platform/processor specific files in the drivers/pci directory because I wanted to leave those file to those that care more about them. Signed-off-by: Andrew Sharp <andywyse6@gmail.com>
* | pci: fix errant data types and corresponding access functionsAndrew Sharp2012-09-02-10/+12
|/ | | | | | | | In a couple of places, unsigned int and pci_config_*_dword were being used when u16 and _word should be used. Unsigned int was also being used in a couple of places that should be pci_addr_t. Signed-off-by: Andrew Sharp <andywyse6@gmail.com>
* pci: declare pciauto functions in headerLinus Walleij2012-03-30-5/+0
| | | | | | | | | | | The FSL PCI driver uses local prototypes for pciauto_[pre|post]scan_setup_bridge(), this does not seem right, so move them to the <pci.h> file. Fixed a small extern declaration too, this is harmless but distracts the view since all other prototypes are explicitly external. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* pci: move pciauto_config_init() to pci.hLinus Walleij2012-03-04-2/+0
| | | | | | | | | | | | | Fixing build regressions for the Integrator I get find that a few boards try to work around the missing declaration of pciauto_config_init() by declaring it in the local scope. This does not make sense when the sibling functions are in <pci.h> so move the function to the header, ridding the build error in the Integrator and getting rid of the local declarations here and there.
