* i2c: mxs_i2c: Squash endless loopMarek Vasut2013-11-13-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* spi: omap3: add support for more word lengthsNikita Kiryanov2013-11-12-24/+82
| | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | 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.

| * malta: setup PIIX4 interrupt routePaul Burton2013-11-09-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | 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>

| * malta: disable L2 cachesPaul Burton2013-11-09-0/+7
| | | | | | | | | | | | | | | | | | | | 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.

| * malta: support for coreFPGA6 boardsPaul Burton2013-11-09-16/+594
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * pcnet: enable the NOUFLO featurePaul Burton2013-11-09-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * pcnet: add cache flushing & invalidationPaul Burton2013-11-09-0/+16
| | | | | | | | | | | | | | | | | | | | | | 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.

| * mips32: detect L1 cache sizes if they're not definedPaul Burton2013-11-09-19/+150
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

This in turn means that the Stack Pointer (SP) register is not set as it is in every other mode of operation, but instead is only zeroed out. To prevent U-Boot SPL from crashing in this obscure JTAG mode, configure the SP to point at the CONFIG_SYS_INIT_SP_ADDR if the SP is zeroed out. Note that in case the SP is already configured, we must preserve that exact SP value and must not modify it. This is important since in every other mode but the JTAG mode, the SPL returns into the BootROM and BootROM in turn loads U-Boot itself. If the SP were to be corrupted, the BootROM won't be able to continue it's operation after returned from SPL and the system would crash. Finally, add the JTAG mode switch identifier, so it's not recognised as Unknown mode.
