2015-03-30imgtec/pistachio: Bring uart driver to modern standardsPatrick Georgi
The console interface changed in upstream, and the driver didn't reflect that yet. This wasn't obvious because the driver wasn't compiled at all.

2015-03-27soc/imgtec/pistachio: Add IMGTEC SPI controller driverIonela Voinescu
The Serial Peripheral Flash Interface (SPFI) block allows communication with various devices over the SPI bus. It uses a configurable transaction interface and it clocks the bus according to the configured command, address, gap (aka dummy) and data lengths. This controller requires the SPI_ATOMIC_SEQUENCING flag set (write and read done in the same transaction) as it cannot directly control CS and will assert/de-assert CS at the beginning/end of a transaction itself. Note that the size of any transfer cannot be greater than 64KB - 1, as this is configured in a 16-bit field. The SOC has 2 SPFI interfaces each of them providing 5 slave select lines. SPFI 0 supports single and dual modes, SPFI 1 supports single, dual and quad modes. For SPFI interface 0: - The block needs the system PLL and the following top level SPI clock registers to be set: - CR_cr_top_spi0clkinternal_CTRL[2:0] with division value - CR_MIPS_CLOCK_GATE[19]: bit cr_top_SPI0CLKOUT_MIPS set - CR_cr_top_SPI0CLKOUT_CTRL[6:0] with division value - The following MFIO configuration parameters are also required: Signal name Pad name MFIO mode spim0_d0_txd MFIO_MIPS_10 0 spim0_d1_rxd MFIO_MIPS_9 0 spim0_mclk MFIO_MIPS_8 0 spim0_cs0 MFIO_MIPS_2 1 spim0_cs1 MFIO_MIPS_1 1 spim0_cs2 MFIO_MIPS_55 1 MFIO_MIPS_28 1 spim0_cs3 MFIO_MIPS_56 1 MFIO_MIPS_29 1 spim0_cs4 MFIO_MIPS_57 1 MFIO_MIMPS_30 1 For SPFI interface 1: - The block needs the system PLL and the following top level SPI clock registers to be set: - CR_cr_top_spi1clkinternal_CTRL[2:0] with division value - CR_MIPS_CLOCK_GATE[20]: bit cr_top_SPI1CLKOUT_MIPS set - CR_cr_top_SPI1CLKOUT_CTRL[6:0] with division value - The following MFIO configuration parameters are also required: Signal name Pad name MFIO mode spim1_d0_txd MFIO_MIPS_5 0 spim1_d1_rxd MFIO_MIPS_4 0 spim1_mclk MFIO_MIPS_3 0 spim1_d2 MFIO_MIPS_6 0 spim1_d3 MFIO_MIPS_7 0 spim1_cs0 MFIO_MIPS_0 0 spim1_cs1 MFIO_MIPS_1 0 MFIO_MIPS_58 1 spim1_cs2 MFIO_MIPS_2 0 MFIO_MIPS_55 2 MFIO_MIPS_31 1 spim1_cs3 MFIO_MIPS_56 2 spim1_cs4 MFIO_MIPS_57 2 BUG=chrome-os-partner:31438, chrome-os-partner:32441 TEST=Tested as bare-metal driver on Pistachio FPGA Change-Id: I3b3e4475976e6fba58cef93b12d997ec5cb26341 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Original-Commit-Id: 621849942e27f7d6cf2c8ade7f2c4d18d2318b91 Original-Change-Id: Ib257eb6236bd2895281175871b4ab979660f1239 Original-Signed-off-by: Ionela Voinescu <ionela.voinescu@imgtec.com> Original-Reviewed-on: https://chromium-review.googlesource.com/217320 Original-Reviewed-by: Vadim Bendebury <vbendeb@chromium.org> Reviewed-on: http://review.coreboot.org/9049 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>

2015-03-23mips: fix bootblock stack definitionsVadim Bendebury
Bootblock stack on Danube should be SRAM and defined separately from the rest of the coreboot stack. The actual coreboot stack will be defined later. The top of the stack should be above the bottom, as the stack grows towards lower addresses. BUG=chrome-os-partner:31438 TEST=ran bootblock on simulator under codescape, observed stack properly initialized.
