2013-11-13i2c: mxs_i2c: Squash endless loopMarek Vasut
The endless waiting for a bit to be set can cause a hang, add a timeout so we prevent such situation. A testcase for such a hang is below. The testcase assumes a device to be present at address 0x50 and a device to NOT be present at address 0x42 . Also note that the "sleep 1" induced delays are imperative for this bug to manifest . i2c read 0x42 0x0.2 0x10 0x42000000 ; sleep 1 ; \ i2c read 0x50 0x0.2 0x10 0x42000000 ; sleep 1 ; \ i2c read 0x42 0x0.2 0x10 0x42000000 The expected result of the above command is: Error reading the chip. Error reading the chip. While without this patch, we observe a hang in the last read from 0x42 precisely when waiting for this bit to be set.

The flag combination "SPI_XFER_BEGIN | SPI_XFER_END" is a common use case of spi_xfer, and it can easily cause an already long line (spi_xfer takes 5 parameters) to go over the 80 character limit. define SPI_XFER_ONCE to be a shorter version of the above flag combination.

2013-11-12spi: omap3: add support for more word lengthsNikita Kiryanov
Current implementation only supports 8 bit word lengths, even though omap3 can handle anything between 4 and 32. Update the spi interface to support changing the SPI word length, and implement it in omap3_spi driver to support the full range of possible word lengths. This implementation is backwards compatible by defaulting to the old behavior of 8 bit word lengths. Also, it required a change to the omap3_spi non static I/O functions, but since they are not used anywhere else, no collateral changes are required.

2013-11-12video: bcm2835: respect the pitch valueAndre Heider
Depending on the firmware's video options [1] the active SDTV or HDTV mode can yield a framebuffer with noncontiguous horizontal lines, giving a messed up display, for both, u-boot and the loaded kernel. Fix this by setting lcd_line_length to the pitch value of the configured framebuffer.

2013-11-12lcd: allow overriding lcd_get_size()Anatolij Gustschin
Remove the redundant lcd_line_length initialisation which sneaked in when an earlier version of the patch of commit 6d330719 has been rebased. Some lcd drivers need to setup lcd_line_length not from the panel_info parameters but by different means. Make the lcd_get_size() weak to allow setting lcd_line_length in a driver specific way.

Resolution consists in adjusting the list of object files in the main branch version. This also applies to two files which are not listed as conflicting but had to be modified: board/compulab/common/Makefile board/udoo/Makefile include/configs/omap4_common.h conflicts are due to the OMAP4 conversion to ti_armv7_common.h on the ARM side, and CONFIG_SYS_HZ removal on the main side. Resolution is to convert as this icludes removal of CONFIG_SYS_HZ. include/configs/pdnb3.h is due to a removal on ARM side. Trivial resolution is to remove the file. Note: 'git show' will also list two files just because they are new: include/configs/am335x_igep0033.h include/configs/omap3_igep00x0.h

2013-11-09malta: add script & instructions to flash U-bootPaul Burton
This patch adds a script which may be used with MIPS Navigator Console and a MIPS Nagivator Probe in order to flash U-boot to a MIPS Malta development board. Please see the newly added doc/README.malta for usage instructions. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
2013-11-09malta: setup PIIX4 interrupt routePaul Burton
Without setting up the PIRQ[A:D] interrupt routes, PCI interrupts will be left disabled. Linux does not set up this routing but relies upon it having been set up by the bootloader, reading back the IRQ lines which the PIRQ[A:D] signals have been routed to. This patch routes PIRQA & PIRQB to IRQ 10, and PIRQC & PIRQD to IRQ 11. This matches the setup used by YAMON. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
2013-11-09malta: store environment in flashPaul Burton
Allow the environment to be stored in the monitor flash of a Malta board. The environment is stored in the final 128KB of the flash, which both leaves the majority of the flash available for U-boot code and also matches the location which YAMON uses. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
2013-11-09malta: enable RTC supportPaul Burton
This is actually required in order for a Linux kernel to boot successfully on a physical Malta board. Without enabling the RTC, a Malta Linux kernel will get stuck in its estimate_frequencies function on boot. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
2013-11-09malta: disable L2 cachesPaul Burton
Malta boards may be used with cores which support L2 caches, however U-boot does not yet support L2 cache for MIPS. Thus for the moment we'll disable L2 caches by setting the L2B bit in Config2. This is specific to MTI/Imagination MIPS cores which is why this is done for the Malta board rather than generically. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
2013-11-09malta: remove cache size definitionsPaul Burton
These will now be detected at runtime, allowing a single U-boot configuration to function correctly with different bitstreams. Without this you may need to re-configure, re-build and re-flash U-boot to your Malta if you flash a new bitstream with a different cache configuration to your old bitstream.

2013-11-09malta: enable CONFIG_PCNET_79C973, PCNET_HAS_PROM, CONFIG_CMD_DHCPPaul Burton
This model of the pcnet is used in current Malta boards, at least in the Malta-R rev 3. Enable support for it. The Malta also has the ethernet controller PROM containing its MAC address, so enable support for that in order to read that MAC address. DHCP is a very useful feature to have available for many networks, enable support for it also. Signed-off-by: Paul Burton <paul.burton@imgtec.com>

2013-11-09malta: support for coreFPGA6 boardsPaul Burton
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>
2013-11-09malta: setup super I/O UARTsPaul Burton
On a real Malta the Super I/O needs to be configured before we are able to access the UARTs. This patch performs that configuration, setting up the UARTs in the same way that YAMON would. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
2013-11-09qemu-malta: rename to just "malta"Paul Burton

2013-11-09pci.h: allow inclusion in assembly sourcePaul Burton
This patch simply #ifdef's out the C-specific parts of pci.h when it is included by an assembly file. This will allow the macros it contains to be used from assembly source as will be done in a followup commit adding support for more modern MIPS Malta boards. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
2013-11-09pcnet: enable the NOUFLO featurePaul Burton
On relatively slow boards (such as the MIPS Malta with an FPGA core card) it can be extremely common for transmits to underflow - to the point where it appears they simply do not work at all. Setting the NOUFLO bit causes the ethernet controller to not begin transmission on the wire until a transmit start point is reached. Setting that transmit start point to the full packet will cause the controller to only transmit the packet once it has buffered it entirely thus preventing any transmit underflows from occuring and allowing the controller to function on slower boards. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
2013-11-09pcnet: add cache flushing & invalidationPaul Burton
Ensure that the view of memory from the CPU & the ethernet controller is coherent at the various points where they exchange data. This prevents stale data from being transmitted or received, and prevents the driver from getting stuck waiting for the ethernet controller to update descriptors when in reality it has but the old values are being read from cache.

2013-11-09mips32: detect L1 cache sizes if they're not definedPaul Burton
For boards such as the MIPS Malta with an FPGA core card it is desirable to be able to detect the L1 cache sizes at runtime, since they are not dependant upon the board but on the FPGA bitstream in use. This patch performs that detection when the CONFIG_SYS_[DI]CACHE_SIZE macros are not defined by the board configuration. In cases where the sizes are detected this patch also removes the restriction that the I-cache & D-cache line sizes must be the same, as this is not necessarily true. If the cache sizes are defined by a configuration then they will be hardcoded as before, so this patch will not add overhead to such boards. Signed-off-by: Paul Burton <paul.burton@imgtec.com>

2013-11-08netconsole loses 2nd character of inputSuriyan Ramasami
Netconsole loses the second character when used as input by either setenv stdin nc or setenv stdin serial,nc if using CONSOLE_CONSOLE_MUX Before a nc_send_packet() to echo the input, a check is done to see if nc_ether is valid. If its not, it waits for an arp request and then sends the packet (which contains the first character of line to be displayed as output). As part of reaping the arp request, the second character is consumed. We protect this by making the call to NetLoop(NETCONS) between input_recursion.
